External Dog Skin Parasite Diseases
Table of Contents
Dog parasite skin infections or problems are commonly caused by canine fleas, dog mange, ticks and ear mites. Fleas are the most common type of parasite found in dogs and cause irritation due to biting or flea allergy dermatitis. Even if you can't see them, fleas are often the cause. Ticks are the second leading cause and can carry the infectious organism that causes lyme disease, Ehrlichiosis and rocky mountain fever among others. They are picked up in fields and wooded areas. Tick related diseases are dependent on how quickly a tick was removed, and the type of tick, as not all ticks carry lyme disease. Mites are closely related to ticks, and are the cause of mange after they burrow into the skin. Lice is from coming in contact with another animal that has lice.

Parasite symptoms in general include itch, scratching, chewing the skin or excessive licking. Diagnosis is based on the location of the dog skin problem on the body, skin symptoms and skin and ear wax texts. Treatment involves immediately addressing any dog skin symptoms, removing the parasite from the dog's body, and then implementing some type of long term prevention plan.
In order to prevent canine parasite problems from returning, a dogs environment should be cleaned thoroughly by vacuuming the area, disinfection and washing all of the dog's items. There are symptoms, diagnostic approaches and treatment options that are unique to each parasite which are described below.

The primary symptom of dog skin parasite problems is usually itch and any skin damage caused by a dog scratching, licking or biting the skin (referred to as a secondary symptom). Skin will usually appear red and inflamed. If you look closely, you may be able to see the actual parasite. Exact symptoms depend on the type of parasite.
While some dog parasite skin problems can be diagnosed based on the symptoms, often trial and error helps to solve the problem, with a dogs response to treatment indicating the cause of any dog skin conditions and other related symptoms.
We don’t want to discourage you from going to the vet, but you can often determine if your dog has fleas, lice, or ticks just by looking at his skin and looking for the symptoms described above. If you discover that your pet has one of these dog skin parasite, you can often treat them yourself at home. Vets can diagnose most dog skin parasites simply by looking at them. For conditions such as the mange, a skin scraping test is performed to determine the type of mange and the appropriate treatment. Vets will diagnose ear mites by taking a swab from your dog’s ear and looking at it under a microscope. The vet can see the mites moving around under the scope.
