Symptoms of Demodex in dogs

Symptoms can be divided into two types. One is the scaly type, which mainly causes hair loss and bald spots in and around the eyelids, forehead, lips, lower neck, elbows, between toes, etc., with clear boundaries, accompanied by mild skin flushing and bran-like flakes. The skin becomes rough and cracked, and some people have small boils. The skin turns grayish white, but the affected area does not itch.

The other type is the pustular type. After being infected with Demodex, small red papules usually appear on the inner thigh and lower abdomen. After a few days, it turns into a small abscess. In severe cases, a large area of ​​red and white small protrusions appears on the inner side of the lower abdomen and thigh, and there is a special odor. At this time, the dog showed restlessness and felt itchy. When a large number of Demodex mites are parasitized, it can lead to systemic skin infection, body hair loss, ulcers formed after pustules rupture, and secondary bacterial infection, systemic symptoms, and death of pets in severe condition.

Symptoms of dog ear itch mite

It is parasitic on the outer ears of dogs and is highly contagious through contact. It can cause a large amount of ear fat secretion and lymph fluid leakage, and Purulence often ensues. If pets feel itchy, they will scratch their ears with their paws from time to time. In addition, they may also show symptoms such as shaking their heads constantly, scratching their ears, chirping, rubbing their ears on objects, and even causing bleeding in the external auditory canal.

Brown-black secretions and epidermal hyperplasia appear in the ear canal. The pet has obvious ear pain and tenderness. He refuses to check the ear, and sometimes makes rotational movements to the side with more serious lesions. When secondary bacterial infection occurs, it can cause suppurative otitis externa and otitis media. Deep invasion can cause encephalitis and cranial nerve symptoms.
