My dog has fleas and the drops aren't working; what should I do? - briefly
If topical flea medication is ineffective, have a veterinarian prescribe an oral or injectable product and simultaneously treat the home with a vet‑approved spray or fogger. Seek veterinary consultation promptly to confirm the infestation and receive a tailored treatment plan.
My dog has fleas and the drops aren't working; what should I do? - in detail
Fleas can survive on a dog despite the use of topical insecticides, especially if the product is applied incorrectly, the dosage is insufficient, or the parasite has developed resistance. Address the problem systematically to eliminate the infestation and prevent recurrence.
First, verify that the treatment was applied according to the manufacturer’s instructions: correct dosage for the dog’s weight, application to the skin at the base of the neck, and a clean, dry area. If any step was missed, re‑apply the product after bathing and drying the coat.
Second, assess the environment. Flea eggs, larvae, and pupae reside in bedding, carpets, and upholstery. Effective control requires:
- Cleaning – vacuum all carpeted areas, rugs, and upholstery daily for at least two weeks; discard the vacuum bag or clean the canister after each session.
- Washing – launder all bedding, blankets, and removable covers in hot water (≥ 60 °C) and dry on high heat.
- Insecticidal treatment – apply a household flea spray or fogger that contains an insect growth regulator (IGR) such as methoprene or pyriproxyfen to interrupt the life cycle. Follow label directions and ensure proper ventilation.
Third, consider alternative or adjunctive medical options. Oral flea medications (e.g., afoxolaner, fluralaner, or nitenpyram) provide rapid knock‑down and sustained protection for up to several weeks. Prescription‑only products may be necessary if resistance is suspected. Consult a veterinarian to select a suitable systemic treatment and to rule out underlying health issues that could impair the efficacy of topicals.
Fourth, maintain preventive measures after the infestation clears. Use a monthly preventive (topical, oral, or collar) that is appropriate for the dog’s size, age, and health status. Regular grooming and inspection of the coat can catch early signs of re‑infestation.
If the dog continues to show signs of fleas after implementing these steps, schedule a veterinary examination. The veterinarian may perform a flea count, test for resistance, and prescribe a combination therapy tailored to the specific situation.
