Canine Allergies 101 - Fleas

Since it is Summer, let's start with flea allergies. Flea allergies are usually seasonal, except in warmer climates, or where fleas have gotten into the house.

Typically, though not always, skin lesions are distributed along the back, and down the back legs and tail; sometimes around the neck as well. Flea allergy can be one of the itchiest diseases found in dogs. Contrary to common thought, the lack of finding a flea on the dog is often a red flag for flea allergies. A dog with flea allergies starts scratching and biting as soon as the flea bites - so either the flea gets destroyed, or finds a more hospitable host. Either way, you will rarely find a flea on a flea allergic animal unless they are really inundated. If you see any fleas on your other pets, and none on the affected one, then flea allergy is definitely part of the problem.

Fortunately, flea allergy is one of the easiest conditions to treat today. Whether you see fleas or not, with an itchy pet, the first thing I ALWAYS do is start a good flea prevention program. Even if fleas are not the whole problem, they often contribute to it. My preferences for flea control are Frontline or Advantage. I've not been very impressed by other commercial flea protection. And while "natural" remedies work well enough for the average dog, I wouldn't count on them for the 100% control you need for a flea allergic dog.
