Canine sarcoptic mange, commonly called scabies, is caused by a parasitic mite. These microscopic mites can infect other animals, but they prefer dogs of all breeds and ages. Their presence causes skin problems.
-
Location
-
Sarcoptic mange most commonly occurs on the dog's elbows, ears, armpits, chest, abdomen and hocks. If not treated, it can spread over the dog's entire body.
Itching
-
The primary symptom is severe itching. Dogs with this infestation will scratch until they have open sores, and they bite and chew on themselves. Infections can occur from the severe scratching, with ulcers and drainage.
Other Signs
-
The dog usually loses hair in the affected areas. Small red bumps typically form that develop yellow crusts.
Progressive Symptoms
-
If the disease is not treated at this point, the dog's skin might darken in the affected areas, and become thick and wrinkled. He develops chronic skin lesions, and his lymph nodes also might swell.
Temperature Affects
-
With sarcoptic mange, the dog's itching is worse in warm weather, or when he sits near a heat vent or stove.
