Treatment for canine otitis externa:

1. Before the treatment of acutely ill dogs, the external auditory canal should be blocked with absorbent cotton balls, then Zhou Tong’s coat should be cut off, and the external auditory canal should be washed with normal saline, 0.1% bromogeramine or 3% hydrogen peroxide solution.

2. For suppurative otitis externa, after cleaning according to the above method, rub the ear canal with antibiotic ointment. In severe cases, wash 1-2 times a day, and then apply ointment.

3. For dogs with obvious systemic symptoms, antibiotics can be used for systemic treatment.

4. Outer ear drainage should be performed for sick dogs with deformed ear shells or long tumors.

Features of canine otitis externa:

1. In the early stage, the external auditory canal was flushed, edematous, and itchy, and a light yellow serous secretion flowed out from the ear canal, staining the hair of the lower part of the ear.

2. Sick dogs are restless, often shaking their heads, or dawdling and scratching their ears. As the disease progresses, local swelling intensifies, or pustules appear, and brown-black foul-smelling purulent secretions flow out, which often leads to hair loss or dermatitis at the base of the ears. Sick dogs have hearing loss.

3. When it becomes chronic, it is good and sometimes bad. Repeated attacks can cause tissue thickening in the ear canal, and even tumors, resulting in thickening of the skin of the pinna, deformation of the pinna, and hearing impairment.
