Wt to do if my shihtzu hav hair fall

Hi Keerthi. 1. Check for the lesions (bacterial/fungal) on the body. If so, a proper treatment would be required. 2. Make sure you are providing a well balanced diet. 3. It can also be seasonal. Try combing your pets hair coat thrice in a week. Use a non medicated shampoo if no infections are seen on the body.
