Stinky ears in dogs are caused by not paying attention to ear canal cleaning, foreign matter or water entering the ear canal but not being cleaned in time, or caused by infections such as parasites and trichocystis. Therefore, it is a very important job to help Samoyed clean the ear canal in time and keep the ear canal hygienic. Your dog's ear canal itself is a place where oil, dirt, and moisture can easily accumulate. Long hair often covers the ear canal, causing poor air circulation in the dog's ear canal, and it is also easy for dirt and moisture to accumulate, leading to infection and inflammation.
