Do Yorkshire Terriers get fleas, and what are the breed‑specific concerns?

Understanding Fleas and Their Lifecycle

What Are Fleas?

Fleas are small, wing‑less insects belonging to the order Siphonaptera. Adult fleas measure 1–4 mm, possess laterally compressed bodies, and feed exclusively on the blood of mammals and birds. Their mouthparts are adapted for piercing skin and sucking blood, which can cause irritation, anemia, and transmit pathogens.

The life cycle consists of four stages: egg, larva, pupa, and adult. Female fleas lay 20–50 eggs daily on the host; eggs fall into the environment, where they hatch into worm‑like larvae within 2–5 days. Larvae feed on organic debris, including adult flea feces, and spin silken cocoons as they develop into pupae. Under favorable conditions, pupae emerge as adults in 5–10 days, but can remain dormant for weeks or months if temperature and humidity are low.

Key characteristics relevant to small breed dogs such as Yorkshire Terriers:

Rapid reproductive rate: a single adult female can generate thousands of offspring in a few weeks.
Preference for warm, sheltered areas: fur folds, bedding, and carpets provide ideal development sites.
Sensitivity of small dogs: limited body mass makes them more prone to anemia from blood loss.
Potential for allergic dermatitis: some dogs develop hypersensitivity to flea saliva, leading to intense itching and secondary skin infections.

Understanding flea biology is essential for implementing effective control measures, especially for breeds with fine coats and higher susceptibility to skin irritation.

The Flea Life Cycle

Yorkshire Terriers are susceptible to flea infestations, and effective control depends on knowing the flea’s developmental sequence. The life cycle comprises four stages: egg, larva, pupa, and adult. Each stage occurs under specific environmental conditions that influence how quickly a population can expand.

Egg – Female fleas lay 20‑50 eggs on the host’s skin; eggs fall off into the environment within hours. Eggs hatch in 2‑5 days when temperature exceeds 10 °C (50 °F) and humidity is above 50 %.
Larva – Worm‑like larvae feed on organic debris, adult flea feces, and skin cells. Development lasts 5‑11 days, requiring warm, dark, and humid surroundings.
Pupa – Larvae spin silk cocoons and enter a dormant stage. Pupae can remain sealed for weeks to months, emerging only when vibrations, carbon‑dioxide, or heat signal a host’s presence.
Adult – Emergent fleas seek a warm‑blooded host within 24 hours. After a blood meal, the female begins egg production within 24‑36 hours, restarting the cycle.

The entire cycle can be completed in as little as three weeks under optimal conditions, allowing a small initial infestation to become severe rapidly. Because Yorkshire Terriers have fine, short coats, fleas are easily detected, but the breed’s tendency toward skin sensitivities can exacerbate irritation once adult fleas begin feeding. Interrupting any stage—through regular vacuuming, washing bedding at high temperatures, applying environmental insecticides, and maintaining topical or oral preventatives—reduces the likelihood of a sustained infestation. Understanding each phase enables targeted interventions that protect the breed’s health and comfort.

Common Flea Habitats

Yorkshire Terriers spend much of their time indoors, yet fleas thrive in environments that provide shelter, warmth, and access to a blood meal. Recognizing where fleas establish colonies helps owners prevent infestations before they affect their small companions.

Fleas commonly occupy:

Carpeted areas – fibers retain humidity and protect eggs and larvae from disturbance.
Pet bedding and blankets – frequent use creates a warm microclimate ideal for development.
Upholstered furniture – seams and cushions hide immature stages, especially in rooms where the dog sleeps.
Cracks in flooring or baseboards – dark, protected spaces allow larvae to pupate undisturbed.
Outdoor grass and leaf litter – shaded, moist patches near the home serve as entry points for adult fleas.

Because Yorkshire Terriers are small and often rest close to owners, any flea presence in these habitats quickly translates to bites on the dog. Regular vacuuming of carpets and upholstery, frequent laundering of bedding at high temperatures, and prompt treatment of outdoor zones reduce the risk of a colony establishing. Continuous monitoring of these environments is essential for maintaining a flea‑free setting for this breed.

Yorkie-Specific Concerns Regarding Fleas

The Yorkie Coat: A Flea Haven?

Yorkshire Terriers possess a fine, silky double coat that sheds minimally. The outer layer consists of straight, glossy hairs, while the undercoat is sparse and soft. This structure creates fewer niches for flea eggs and larvae compared to dense, wiry coats, reducing the likelihood of a heavy infestation.

Despite the coat’s low density, Yorkies are not immune to fleas. Their small size and close skin contact with the hair surface allow adult fleas to attach easily. The breed’s tendency to maintain a warm micro‑environment during indoor living further encourages flea activity.

Key factors influencing flea risk in Yorkie coats:

Minimal undercoat limits hidden egg deposition.
Smooth hair surface permits easier detection of adult fleas during grooming.
Short hair length reduces moisture retention, a condition fleas favor.
Frequent grooming sessions increase early identification of infestations.

Effective management combines regular grooming with targeted parasite control. Brushing several times a week removes loose hairs and reveals early flea presence. Veterinary‑approved topical or oral preventatives, applied according to the product’s schedule, maintain a flea‑free status. Environmental measures—frequent vacuuming, washing bedding at high temperatures, and limiting outdoor exposure to infested areas—complement the breed‑specific coat advantages and minimize flea burden.

Skin Sensitivity in Yorkshire Terriers

Yorkshire Terriers possess a fine, silky coat that offers limited protection against external irritants. Their skin is prone to inflammation, especially when exposed to flea bites, which can trigger flea‑allergy dermatitis (FAD). FAD manifests as intense itching, redness, and secondary infections, often escalating quickly in this breed due to their heightened sensitivity.

The breed’s small size and low body fat contribute to rapid heat loss, making their skin more vulnerable to dryness and cracking. Environmental factors such as low humidity, harsh shampoos, and frequent bathing can exacerbate these conditions, reducing the natural barrier function and facilitating parasite attachment.

Effective management focuses on prevention and gentle care:

Use veterinary‑approved, low‑pesticide flea preventatives designed for small breeds.
Choose hypoallergenic shampoos without sulfates or fragrance additives; limit baths to once a month unless a medical condition requires more frequent washing.
Apply a moisturizer or barrier cream containing ceramides after bathing to restore lipid balance.
Inspect the coat daily for signs of flea activity, especially around the neck, tail base, and behind the ears.
Maintain a clean living environment: vacuum regularly, wash bedding in hot water, and treat indoor spaces with flea‑control sprays that are safe for pets.

Dietary support can reinforce skin health. Foods enriched with omega‑3 fatty acids, vitamin E, and zinc help reduce inflammation and improve coat quality. Supplements should be introduced under veterinary supervision to avoid excess intake.

Regular veterinary examinations enable early detection of allergic reactions and allow timely adjustments to flea‑control protocols. Monitoring skin condition, recording any flare‑ups, and adjusting preventive measures accordingly are essential for keeping Yorkshire Terriers comfortable and free from flea‑related complications.

Allergic Reactions to Flea Bites

Yorkshire Terriers frequently develop flea‑induced allergic dermatitis because their skin is thin and prone to irritation. The immune system of many individuals overreacts to proteins in flea saliva, producing a rapid, localized response.

Typical manifestations include:

Intense itching concentrated around the neck, base of the tail, and lower back.
Red, raised papules or hives that may merge into larger inflamed patches.
Hair loss and secondary bacterial infection from excessive scratching.
Scabs or crusted lesions that appear within 24 hours of a bite.

The breed’s small size amplifies the impact of a modest flea load; a few bites can trigger a severe reaction. Genetic predisposition toward atopic skin conditions further increases sensitivity. Owners often observe that symptoms worsen during warm months when flea activity peaks.

Diagnostic confirmation relies on:

Physical examination of characteristic lesions.
Flea combing to detect live parasites or recent flea debris.
Intradermal allergy testing or serum IgE assays to identify flea saliva as the allergen.

Effective management combines immediate symptom control with long‑term flea prevention:

Antihistamines or corticosteroids prescribed by a veterinarian to reduce inflammation.
Topical or oral flea‑killing products applied consistently according to label directions.
Regular washing of bedding and grooming tools to eliminate residual flea allergens.
Environmental treatments, such as insecticide‑treated sprays, in areas where the dog spends time.

Because Yorkshire Terriers are especially vulnerable, proactive flea control is essential. Failure to maintain a strict regimen often results in recurrent allergic flare‑ups, chronic skin damage, and reduced quality of life.

Identifying Fleas on Your Yorkshire Terrier

Visual Inspection Techniques

Visual inspection remains the most immediate method for confirming flea presence on Yorkshire Terriers. Their fine, silky coat requires systematic examination because fleas often hide near the skin surface and can be overlooked in dense fur.

Begin by securing the dog in a calm position, using a gentle restraint if necessary. Conduct the assessment under bright, natural light or a high‑intensity lamp; shadows obscure small insects and their droppings. Run a fine‑toothed flea comb from the base of the skull down the neck, across the shoulders, and along the back. The comb’s teeth separate the hair, exposing adult fleas, nymphs, or flea dirt (dark specks that turn reddish when moistened with saline).

Focus on the following regions, where Yorkshire Terriers are most vulnerable:

Neck and collar line: Warm, moist skin encourages flea development.
Around the ears: Thin skin and limited hair density provide easy access.
Armpits and groin folds: Humidity creates a favorable microenvironment.
Tail base and hindquarters: Frequent grooming by the owner often neglects these spots.

Observe the skin for redness, small bite marks, or localized inflammation. Flea dirt appears as tiny black particles; a saline test (adding a drop of saline solution) can confirm its nature—fleas excrete digested blood, which turns reddish under the solution.

If a flea is detected, note its stage (adult or immature) and count the number of individuals. This information guides treatment intensity and informs whether an environmental control program is required. For Yorkshire Terriers, the thin coat offers limited protection against flea penetration, making early visual detection critical to prevent secondary skin infections and allergic reactions that are more common in this breed.

«Flea Dirt» Detection

Yorkshire Terriers are prone to flea infestations, and early identification of flea presence relies on recognizing flea dirt—tiny black specks that are digested blood. Detecting flea dirt allows owners to intervene before a full‑blown infestation develops, which is critical for this breed because their fine, silky coat can conceal adult fleas and their skin is sensitive to allergic reactions.

Flea dirt appears as 0.5‑mm dark particles that resemble pepper. When moistened with water or saline, the particles turn reddish, confirming the presence of blood. The following procedure maximizes detection accuracy for Yorkshire Terriers:

Visual inspection: Part the hair on the neck, back, and tail base; examine the skin for specks.
Moistening test: Place a small amount of water on a suspected speck; observe color change to reddish within seconds.
Sticky tape method: Press clear adhesive tape onto the area, then view the tape under a light source; flea dirt will be visible as dark spots.
Fine‑tooth comb: Run a flea comb through the coat, especially along the spine and hindquarters; collect any debris on a white surface and apply the moistening test.

Breed‑specific considerations include:

Coat texture: The soft, low‑shedding coat can trap flea dirt, making it harder to spot without systematic inspection.
Skin sensitivity: Yorkshire Terriers often develop flea allergy dermatitis; even minimal flea dirt can trigger intense itching and secondary infections.
Size: Their small body mass means that a few adult fleas can cause a proportionally larger blood loss, increasing the risk of anemia.

Regular weekly checks using the steps above, combined with routine preventive treatments, reduce the likelihood of severe flea‑related complications in Yorkshire Terriers.

Behavioral Signs of Fleas

Yorkshire Terriers often exhibit distinct behaviors when afflicted by fleas. Persistent scratching, especially around the neck, ears, and tail base, signals a reaction to bites. Frequent licking or chewing of the same areas accompanies the itch and may lead to hair loss. Restlessness during rest periods, manifested by frequent repositioning or an inability to settle, reflects discomfort. Sudden changes in activity level, such as reduced playfulness or reluctance to exercise, often correlate with irritation and possible secondary skin infection.

Key behavioral indicators include:

Repetitive scratching or pawing at specific body regions.
Excessive licking or mouthing of fur and skin.
Increased agitation while lying down or sleeping.
Visible signs of irritation, such as redness, scabs, or small bite marks.
Diminished enthusiasm for walks, training, or social interaction.

Yorkshire Terriers’ fine, single‑coated fur and delicate skin amplify these signs. Their small stature limits the amount of fur available to conceal fleas, making early detection essential. Prompt observation of the listed behaviors enables timely intervention, reducing the risk of anemia, allergic dermatitis, and secondary infections that disproportionately affect this breed.

Preventing Fleas in Yorkshire Terriers

Topical and Oral Preventatives

Yorkshire Terriers are prone to flea infestations because their short, fine coats provide limited protection. Effective control relies on both topical and oral preventatives, each with breed‑specific considerations.

Topical treatments are applied directly to the skin, usually between the shoulder blades. They spread across the surface through the animal’s natural oil secretions. For Yorkshire Terriers, the small body size demands precise dosing; a product formulated for dogs under 10 lb is required to avoid overdose. Many spot‑on solutions contain pyrethrins or imidacloprid, which are safe for the breed when used according to label instructions. However, the breed’s sensitive skin can react to alcohol‑based carriers; products with a hypoallergenic base reduce the risk of dermatitis.

Oral preventatives are administered as chewable tablets or flavored pills. They work systemically, killing fleas after ingestion. The active ingredients typically include afoxolaner, fluralaner, or spinosad. Yorkshire Terriers tolerate these compounds well at the low dose prescribed for dogs weighing 5–10 lb. Daily or monthly dosing schedules maintain constant blood levels, preventing flea development before eggs are laid. Food‑related timing is important: tablets should be given with a meal to ensure optimal absorption.

Key points for selecting and using preventatives with Yorkshire Terriers:

Choose formulations labeled for dogs under 10 lb; avoid “large‑dog” concentrations.
Verify that the product is free of harsh solvents or fragrances that may irritate delicate skin.
Follow the exact interval recommended on the label—typically 30 days for oral agents, 4 weeks for most spot‑ons.
Monitor the dog for signs of adverse reactions (redness, itching, vomiting) after the first application; discontinue and consult a veterinarian if symptoms appear.
Combine preventive measures with regular grooming and environmental control (vacuuming, washing bedding) to break the flea life cycle.

When used correctly, topical and oral preventatives provide complementary protection, minimizing the likelihood of flea infestations while respecting the Yorkshire Terrier’s unique physiological traits.

Environmental Control Measures

Yorkshire Terriers are particularly vulnerable to flea infestations because their fine coat can hide parasites and their delicate skin reacts quickly to irritation. Effective environmental control reduces the likelihood of bites and the subsequent allergic dermatitis that often affects this breed.

Regular cleaning of the home environment is essential. Vacuum carpets, rugs, and upholstery at least twice weekly, discarding the bag or emptying the canister immediately to prevent re‑infestation. Wash all pet bedding, blankets, and removable covers in hot water (≥ 60 °C) weekly. Replace or clean pet‑specific toys and grooming tools after each use.

Control outdoor areas where fleas thrive. Keep grass trimmed and remove leaf litter to limit humid microhabitats. Apply a pet‑safe insect growth regulator to perimeters, following label directions. Restrict the dog’s access to areas frequented by wildlife such as rodents or birds, which can serve as flea reservoirs.

Implement chemical and non‑chemical barriers inside the house. Use a residual, low‑toxicity flea spray on baseboards, under furniture, and in cracks where adult fleas hide. Consider diatomaceous earth on carpets and pet zones, ensuring it remains dry to retain efficacy. Rotate products with different active ingredients to prevent resistance.

Monitor and document findings. Keep a log of cleaning schedules, treatment applications, and any flea sightings. Early detection allows prompt escalation of control measures before an infestation becomes severe.

By maintaining a consistently clean environment, limiting exposure to external flea sources, and applying targeted treatments, owners can significantly lower the risk of flea‑related problems for Yorkshire Terriers.

Regular Grooming Practices

Yorkshire Terriers possess a fine, silky coat that can trap flea debris and moisture if not maintained. Frequent brushing removes loose hair, distributes natural oils, and allows early detection of parasites. A soft‑bristle brush followed by a fine‑toothed comb should be used at least once daily, focusing on the back, tail, and behind the ears where fleas often hide.

Bathing with a veterinarian‑approved flea shampoo every three to four weeks reduces adult flea populations and soothes irritated skin. After each bath, thoroughly dry the coat to prevent fungal growth, which Yorkshire Terriers are predisposed to due to their dense fur.

Nail trimming, ear cleaning, and dental care are integral to overall health and support flea management. Trim nails weekly to avoid breakage, clean ears with a cotton ball dampened with a gentle cleanser to remove wax and debris, and brush teeth several times a week to reduce bacterial buildup that can exacerbate skin issues.

A practical grooming routine:

Brush: soft‑bristle brush + fine‑toothed comb, daily
Inspect: skin, neck, and tail base for flea movement or bite marks during brushing
Bathe: flea‑specific shampoo, every 3–4 weeks, followed by complete drying
Trim nails: weekly, ensuring no over‑cutting
Clean ears: twice weekly, using a vet‑recommended solution
Brush teeth: 2–3 times weekly with a canine toothbrush

Consistent grooming diminishes flea habitats, supports early parasite detection, and addresses Yorkshire Terrier‑specific sensitivities such as skin irritation and coat matting.

Treating Flea Infestations in Yorkshire Terriers

Veterinary-Prescribed Treatments

Yorkshire Terriers are prone to flea infestations because their short coats and active lifestyle provide ample opportunity for exposure. Veterinary‑prescribed treatments address both immediate eradication and long‑term prevention, taking the breed’s small size and sensitive skin into account.

Prescription‑only oral medications such as nitenpyram, spinosad, afoxolaner, and milbemycin oxime are effective within hours and are dosed according to body weight. For Yorkshire Terriers, the dosage range is narrow; veterinarians calculate the exact milligram amount to avoid overdose. Oral options are preferred when topical applications risk irritation on the delicate dermis.

Topical spot‑on products containing selamectin, fipronil, or imidacloprid provide a 30‑day barrier against adult fleas and emerging larvae. Veterinarians recommend applying the solution directly to the skin at the base of the neck, where the dog cannot lick it off. Small‑breed formulations contain reduced concentrations to match the Yorkie’s lower body mass.

Prescription collars, such as those delivering imidacloprid and flumethrin, release active ingredients continuously for up to eight months. Collars are useful for households with multiple pets, but veterinarians advise monitoring for any signs of skin irritation, especially around the neck area.

Key considerations for Yorkshire Terriers include:

Weight‑based dosing: precise calculations prevent toxicity.
Skin sensitivity: choose hypoallergenic formulations; avoid products with high alcohol content.
Concurrent conditions: dogs with hypothyroidism or atopic dermatitis may require adjusted treatment intervals.
Drug interactions: inform the veterinarian of any existing medications, including heartworm preventatives, to avoid adverse reactions.

Veterinarians typically schedule a follow‑up examination two weeks after initiating treatment to assess efficacy and adjust the regimen if necessary. Regular flea‑preventive administration, combined with environmental control measures such as washing bedding and treating the home environment, ensures sustained protection for Yorkshire Terriers.

Over-the-Counter Solutions

Yorkshire Terriers, despite their diminutive size and fine coat, are susceptible to flea infestations. Their skin is thin and prone to irritation, making careful product selection essential.

Common over‑the‑counter options include:

Topical spot‑on treatments – applied to the neck area; provide month‑long protection; formulations with fipronil or imidacloprid are widely used.
Oral chewable tablets – contain nitenpyram or spinosad; deliver rapid kill within hours; dosage must be calculated per pound of body weight.
Flea collars – release low‑dose insecticides such as flumethrin; effective for up to eight weeks; ensure collar fits snugly without restricting movement.
Shampoos and sprays – contain pyrethrins or neem oil; useful for immediate relief; require thorough rinsing to avoid residue buildup.

Breed‑specific concerns dictate avoidance of products containing pyrethroids, which can cause neurotoxicity in small, sensitive dogs. Formulations with high alcohol content or strong fragrances may exacerbate dermatitis. Dosage calculations should reference the dog’s weight, not its age, because Yorkshire Terriers often weigh less than five pounds.

When selecting an OTC flea remedy, verify that the label lists a weight range encompassing the pet’s current mass. Apply or administer exactly as directed; do not exceed the recommended frequency. Observe the animal for signs of itching, redness, vomiting, or lethargy after treatment; discontinue use and seek veterinary advice if adverse reactions appear.

Addressing Environmental Contamination

Yorkshire Terriers are highly susceptible to flea infestations because their fine coat and active lifestyle increase exposure to contaminated environments. Effective control begins with eliminating sources of infestation in the home and surrounding areas.

Regular cleaning of flooring, upholstery, and bedding removes flea eggs and larvae that accumulate in dust and debris. Vacuuming should be performed daily; dispose of the vacuum bag or empty the canister immediately to prevent re‑infestation. Wash all fabrics in hot water (minimum 130 °F) at least once a week.

Chemical and biological treatments must be selected with the breed’s small size and sensitive skin in mind. Use products labeled for small dogs, apply according to manufacturer instructions, and avoid contact with eyes and mucous membranes. For outdoor spaces, apply environmentally safe insect growth regulators to grass, mulch, and pet‑frequented zones; repeat applications according to the product’s residual period.

Key practices for minimizing environmental contamination:

Keep grass trimmed and remove leaf litter where fleas develop.
Restrict the dog’s access to untreated wildlife habitats.
Store pet medications in sealed containers away from food preparation areas.
Rotate spot‑treatments with non‑chemical options such as diatomaceous earth on carpets and in cracks.

Monitoring the environment includes inspecting the dog’s coat after walks, checking for flea dirt on bedding, and using a flea comb weekly. Prompt detection allows immediate intervention, reducing the likelihood of a full‑scale infestation and protecting the breed’s health.

Long-Term Management and Prevention

Year-Round Flea Control

Yorkshire Terriers are prone to flea infestations throughout the year, making continuous preventive measures essential. Fleas thrive in warm indoor environments, even when outdoor temperatures drop, so seasonal gaps in treatment leave the breed vulnerable to bites, skin irritation, and secondary infections.

Key components of an effective year‑round program include:

Veterinary‑approved topical or oral preventatives applied monthly, selected for the dog’s weight and health status.
Environmental control: regular vacuuming, washing of bedding at high temperatures, and use of insecticidal sprays or foggers in living areas.
Routine inspections: weekly combing with a fine‑toothed flea comb to detect early infestations, focusing on the neck, tail base, and behind the ears where Yorkies often hide parasites.
Health monitoring: tracking skin condition, scratching frequency, and any signs of anemia, which can develop rapidly in small breeds.

Consistency in administration, combined with diligent household hygiene, reduces the risk of flea‑borne diseases and minimizes the need for reactive treatments that may stress a Yorkshire Terrier’s delicate skin.

Consulting Your Veterinarian

Veterinarians provide the most reliable assessment of flea risk for Yorkshire Terriers, whose delicate skin and fine coat require specialized care. A professional examination confirms the presence of parasites, identifies secondary skin irritations, and evaluates any underlying health conditions that may increase susceptibility.

During the appointment, request the following information:

Recommended flea‑prevention products formulated for small‑breed dogs, including dosage calculations based on the Terrier’s weight.
Guidance on safe bathing frequencies and appropriate shampoos that will not strip the coat’s natural oils.
Assessment of potential allergic reactions unique to the breed, such as hypersensitivity to common insecticides.
A schedule for routine re‑examinations to monitor effectiveness and adjust treatment as the dog ages.

Bring a detailed record of the Terrier’s diet, recent medications, and any observed scratching or skin changes. This enables the veterinarian to tailor a prevention plan that minimizes adverse reactions while maintaining optimal coat health.

Follow the prescribed regimen precisely, and report any unexpected symptoms—such as excessive redness, hair loss, or lethargy—promptly. Continuous veterinary oversight ensures that flea control remains effective and that breed‑specific concerns are addressed before they develop into more serious health issues.

Monitoring for Reinfestation

Yorkshire Terriers can host flea infestations, and their small size, fine coat, and sensitive skin create distinct monitoring challenges. Continuous observation after treatment prevents a second wave that can exacerbate itching, dermatitis, and secondary infections.

Effective reinfestation surveillance includes:

Daily visual checks of the coat, especially behind the ears, at the neck base, and near the tail. Flea dirt appears as tiny black specks; a wet‑to‑dry swipe on a white surface confirms presence.
Weekly tactile examinations: run fingers through the fur to feel for live fleas or movement. The breed’s short hair makes detection easier than in long‑haired dogs.
Routine assessment of scratching behavior. An increase in pawing at the face or frequent licking of the skin often precedes visible fleas.
Environmental inspections twice a month. Scan bedding, carpet seams, and furniture cracks for adult fleas or eggs, focusing on areas where the terrier rests.
Record‑keeping of any findings. A simple log noting date, location, and observed signs assists in identifying patterns and evaluating the efficacy of preventive products.

Professional guidance should be sought if any signs appear within two weeks of completing an initial treatment. Veterinarians may recommend a follow‑up topical or oral preventive, adjusted for the breed’s sensitivity to certain chemicals. Maintaining the outlined schedule reduces the likelihood of a resurgence and supports the terrier’s overall health.
