Sarcoptic Mange and Old Dog's
Overview - Sarcoptic mange commonly know as scabies, is caused by an external parasite that burrows deep into the skin. It is contagious to other pets and occurs in many different animals. It causes intense itchiness, especially affecting the ear margins, elbows, and face. People can pick up this disease from their pet and show symptoms of itching, but it goes away by itself in a short time and does not require treatment in most cases.
It is important to note that the diagnosis of this skin condition, like most skin conditions, can not be made just by looking at a pet. Diagnostic tests are mandatory to arrive at a correct diagnosis and achieve a satisfactory outcome to therapy. Stating that an animal looks "mangey" is not the same thing as making a positive diagnosis of mange. Pets that have Ringworm , Demodex. and allergies can look like they have Sarcoptic mange.
Parasite target - these mites like to tunnel in the upper layers of the skin
Symptoms - The constant scratching results in hair loss and damage to the skin by self-mutilation. Although the lesions start on the thinly haired areas such as the ears, muzzle and around the eyes, if let go the condition can spread over the entire body. Serum ( the clear component of blood) seeps out of the tunnels to the surface of the skin and causes thick scabs to form.
Treatment - Ivermectin is the treatment of choice for sarcoptic mange. It is usually administered in two doses, two weeks apart. The dog may also require antibiotics and medicated baths for skin infections and itch relief. The family should be cautious about handling the dog, since sarcoptic mange is contagious.
Prevention - Good nutrition and plenty of play and exercise are always important to maintain the proper balance to fight off disease. All pets in a household that has a pet diagnosed with this disease should also be treated.
