thanks so much for all the information. i will look into the dog food you mentioned. and i will take a harder look around his eyes and nose. i dont know what other test i should ask my vet to run. we tested for cushings, his liver and thyroid. he acts like his usual yorkie self. do you have any thoughts on this? it was my vet who thought i could try adding fish supplement. so i started adding the supp to his food a couple weeks back. do you think that really does anything? i would love to see your yorkie. about sunscreen, should i get regular sunscreen for humans?
