Dog -shaped mites are also called canine hair follicle disease or canine lipid mites. Creep mites are mostly parasitic in the ear canal, eye, mouth, and four inner hair follicles of the dogs, and a small part of the sebaceous glands will be parasitic. Inside. Itching of the sick dog is a more common and refractory skin disease.

1. Pathogen

Creep mites are a small parasitic mite. Female is 0.25-0.30 mm long and 0.045 mm wide. The male is 0.22-0.25 mm long and about 0.045 mm wide. The shape of the worm can be divided into three parts: head, chest, and abdomen. The mouth is composed of a pair of whiskers, a pair of thorns, and a lower panel. Close lines. The germ hole of the male is opened on the back. The female reproductive hole is on the abdomen. The eggs are shuttle-shaped, about 0.07-0.09 mm long. The history of development includes 4 stages of eggs, larvae, nymph, and adults.

2. Cause

Skin disease caused by creep mite disease. There are very few creep mites on dogs as normal. When mites are overly proliferated, creep diseases with clinical symptoms will occur. Dogs with young systemic creep diseases generally have a hereditary tendency. Adult creep diseases are usually related to potential diseases (such as Kuchin's disease, hypothyroidism), immunotherapy caused by immunosuppressive drugs or cancer.
