I had the same problem with my Chihuahua mix. My veterinarian told me that I can give her a bath every day if I want or as often as I can and that should help. I thought it wasn't good to give dogs baths too often, but she assured me that it would be fine and quite healthy for her and would definitely help with her shedding. So I tried it and it really helped! Now not only has her shedding improved, but she always looks so pretty!!
