What to do if a dog is infested with fleas? - briefly
Start a veterinarian‑approved flea control—apply a prescribed oral or topical medication and give the dog a medicated bath to eliminate current pests. Then wash all bedding, vacuum the house thoroughly, and continue the treatment as directed to interrupt the flea life cycle.
What to do if a dog is infested with fleas? - in detail
A dog suffering from a flea infestation requires a coordinated approach that addresses the animal, its environment, and future protection.
First, isolate the pet to prevent further spread. Bathe the dog with a flea‑killing shampoo, following the product’s instructions for water temperature, dilution, and contact time. After the bath, apply a veterinary‑approved topical or oral adulticide, ensuring the correct dosage based on weight. Use a comb with fine teeth to remove dead insects and eggs from the coat; repeat the combing daily for at least one week.
Second, treat the living space. Wash all bedding, blankets, and removable fabrics in hot water (minimum 60 °C) and dry on high heat. Vacuum carpets, rugs, and upholstery thoroughly, then discard the vacuum bag or clean the canister. Apply a household flea spray or fogger that contains insect growth regulators (IGRs) such as methoprene or pyriproxyfen; follow label directions for room size and ventilation. Repeat environmental treatment after seven days to target newly hatched larvae.
Third, address outdoor areas where the dog spends time. Trim grass and vegetation to reduce humidity, which favors flea development. Scatter a pet‑safe outdoor larvicide or use a dust containing IGRs in shaded, high‑traffic zones. If the dog frequently visits other homes, request that those environments be treated similarly.
Fourth, implement a preventive regimen. Administer a monthly oral or topical flea preventer recommended by a veterinarian. Rotate products if resistance becomes a concern, but maintain consistent timing to keep the parasite cycle broken. Regular grooming with a flea‑comb can detect early reinfestations.
Finally, monitor the dog’s health. Observe for signs of irritation, anemia, or allergic reactions. If excessive scratching, hair loss, or lethargy develop, seek veterinary care promptly; additional treatments such as corticosteroids or antibiotics may be necessary.
