Does Your Dog Have Flea Bite Dermatitis?

Although there are many advances in dog health care, flea bite dermatitis is still a common problem. In fact, it is the most common dermatology disease in the domestic dog. In the summer, the disease is more prevalent, and warm climates can help the infestation to persist all year through.

Why does this happen?

When flea bites, it injects the saliva that has many compounds that are similar to histamine, like enzymes, polypeptides and amino acids that may cause reactions. At the first times, the reactions can happen as soon as 15 minutes or delayed until 48 hours later. Biologically speaking, when injected with saliva, dog’s blood increases in IgE and IgG antiflea antibodies. With continuous exposure, the levels of these compounds decrease greatly and stop the skin from having reactions, or have reactions much later at a small degree. Simply put, this means the development of immunologic tolerance.

Does your dog have it?

Symptoms of flea bite dermatitis vary much, and depend on the flea exposure, the duration of the disease, if your dog has any other skin disease or not, the level of hypersensitivity of the dog, and the effects of medical treatment at the infected time. The most common signs including occasional scratching.

The pruritus from this dermatitis can be intense and spread all over the body. There will probably be papulocrustous lesions over the lower back, end of the tail, the inner thighs and posteriors. There are some dogs that will be more sensitive in the flanks, caudal, medial thighs, ventral abdomen, lower back , neck, and ears. Once infected, the dog will be very restless and uncomfortable. He would probably spend most of his time scratching, licking, rubbing chewing and nibbling his skin. More than often, the hair or fur on his skin are stained brown from all the licking and can be broken off. Other symptoms include erythema, inflamed skin, scaling and papules with the reddish brown crust. The first areas to be infected are the rump and the end of the tail.

In extreme cases, extensive areas of erythema and even mental trauma symptoms can be found. When the disease becomes chronic, severe seborrhea and hyperpigmentation can develop.
