Symptoms of canine mange disease:

1. The skin will start to become red and small red boils will appear, which will then turn into blisters. When the blisters burst, a thick yellow oil will flow out. Exudate, which dries to form a fish-like scab.

2. Hair loss occurs on the eyelids and legs, the skin becomes thickened and red with bran-like scales, and then the skin turns reddish-brown.

3. The affected area is getting larger and larger, and the skin begins to bleed.

The reasons why dogs get canine mites:

1. Bathing dogs too frequently causes their stratum corneum to become thinner and the skin lacks moisture, which reduces the skin barrier. Caused by functional decline.

2. Puppies with weak immune systems, or dogs with reduced body resistance due to malnutrition, are more likely to develop canine mite disease.

3. If the dog lives in a humid environment with poor sanitary conditions, it is easy for mites, fungi, bacteria and other organisms to breed in this environment.
