What is this? 😍 #parasite #vetlife #medvet #vettech #dog #bulldogpuppy #frenchie #demodex #microscope #veterinary #veterinarymedicine Demodectic mange, this mite is shaped like a cigar with eight legs. Dogs that are sensitive to the demodectic mites may develop a few (less than 5) isolated lesions (localized mange) or they may have generalized mange, in which case, there are more than 5 lesions involving the entire body or region of the body. Most lesions in either form develop after four months of age.
The lesions and signs of demodectic mange usually involve hair loss; crusty, red skin; and at times, a greasy or moist appearance. The mites prefer to live in the hair follicles, so in most cases, hair loss is the first noted sign. Usually, hair loss begins around the muzzle, eyes, and other areas on the head. The lesions may or may not itch. In localized mange, a few circular crusty areas will be noted, most frequently on the head and forelegs of young dogs 3-6 months of age. Most of these lesions will self heal as the puppies become older and develop their own immunity. Persistent lesions will need treatment that will be described later. In cases in which the whole body is involved (generalized mange), there will be areas of hair loss over the entire coat, including the head, neck, abdomen, legs, and feet. The skin along the head, side, and back will be crusty and oftentimes inflamed. It will often crack and ooze a clear fluid. Hair will be scant, but the skin itself will often be oily to the touch. There is usually a secondary bacterial infection. Some animals can become quite ill and develop a fever, lose their appetite, and become lethargic. Patients with generalized demodectic mange need immediate vigorous treatment.
