This is probably caused by an allergic reaction. first of all make sure you de-flea Fenton regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or cyclosporin in order to stop the allergy.

It can be behavioral but it is likely due to an allergy. The area is red and inflamed and may be infected. An allergies to fleas or something in the environment such as grasses and pollen can cause this. I would see your vet about medication toc clear it and stop the cycle
