Today’s Pet meds Spotlight is on Flea Allergy Dermatitis, (Hot Spots) is a skin disease (dermatitis) caused by your pet’s allergic reaction to fleas. Pets will usually have inflamed skin, hot, red, and itchy. Often the skin becomes smelly because yeast and bacteria grow well on unhealthy, inflamed skin. When your pet scratches, the bacteria are rubbed deep into the skin and hot spots develop. Hot spots are just infected sores.
Pets with flea allergy dermatitis are so sensitive they can develop hot spots if bitten just twice a month by fleas. Your pet is having an allergic reaction to flea saliva, feces and exoskeleton.
Treated early enough, it can be handled topically, but in most cases an oral medication is prescribed in addition to topical treatment.
