Flea allergy dermatitis (FMD) is one of the most common skin conditions in dogs and cats, accounting for tens of thousands of veterinarian visits each year.
Whether you’re currently dealing with a flea infestation or not, it’s important to familiarize yourself with FAD. Knowing the basics of this conditions, such as the signs and symptoms, will allow you to make smarter decisions regarding your pet’s health.
Flea allergy dermatitis: The Scoop
So, what exactly is flea allergy dermatitis (FAD)? In short, it’s an allergic skin sensitivity to flea saliva. When a flea finds a host, it will bite into the flesh to draw blood. Pets that are allergic to fleabites have the condition FAD.
The fact is that all pets are irritated by fleas, but only some pets are allergic to them. If your pet doesn’t exhibit any symptoms after being bitten by a flea, then they don’t have FAD.
Why Fleabites Cause Allergic Reactions
Fleabites oftentimes cause allergic reactions in pets and humans due to their saliva. Fleas draw blood by piercing their host’s skin with a hollow syringe-like needle. During this process, some of the flea’s saliva enters the host’s body, at which point it may cause an allergic reaction.
Not-So-Fun Fact: Scientists have identified 15 different allergens in the flea’s saliva. And it only takes a single one of these allergens to trigger a reaction. This is why FAD is such a common and widespread condition in pets.
