Companion Dog Flea Allergy Dermatitis

Flea allergy dermatitis is the most common skin disease in dogs, causing intense pruritus from hypersensitivity to flea saliva.

Key Facts

Even a single flea bite can trigger severe reactions in allergic dogs
Affected dogs experience intense itching, self-trauma, and secondary infections
Strict flea control is essential and must include treatment of the environment
Modern systemic flea preventatives are highly effective and safe

Welfare Considerations

Flea allergy dermatitis causes relentless itching that severely impacts quality of life. Affected dogs scratch, bite, and lick until they create open wounds that become infected. The chronic nature of untreated allergy means weeks or months of intense discomfort. Many owners do not recognize the flea allergy basis of their dog's skin disease, delaying effective treatment and prolonging suffering.

What You Can Do

Use veterinary-recommended flea prevention year-round for allergic dogs
Treat all pets in the household plus the home environment for fleas
Seek veterinary diagnosis if your dog has unexplained skin disease
Provide immediate treatment when flea allergy signs appear
