Look for symptoms of demodectic mange. Demodectic mange is characterized by thinning of the fur on a small piece of skin that can be scabbed. The scabies can be limited to one part or spread throughout the body. Demodectic mange is not contagious and cannot move into the human body.
- Demodectic mange, also known as a demodex or “red scab,” is commonly caused by mites that move from mother to child during the first few days of life. The mites are present in all dogs and usually will not cause problems.
- Scabies arise when the mite population breeds in dogs whose immune system is as undeveloped as puppies under the age of 18 months, older dogs and dogs with weak immune systems.
- When the mites are concentrated in one or two separate parts of the skin, this condition is known as a local demodectic mange that appears as a scaly, balding patch, usually on a dog’s face. Local demodectic mange is most common in puppies and usually disappears by itself without treatment.
- When the scabies appear in large areas or on the whole body of the dog, the mange is known as general or even demodectic mange. This type of scabies makes skin bald and scaly, which can be very itchy. When the dog scratches, the wound can form. The wound is susceptible to bacterial infections that smell unpleasant. Demodectic mange commonly occurs in dogs with weak immune systems and will require treatment.
- The most resistant demodectic mice are known as demodectic pododermatitis, which only appears on the legs and is accompanied by bacterial infections. This type of scabies is difficult to diagnose or treat.
