Has anyone had a problem with their Yorkie itching or scratching themselves more than normal? Our little Yorkie seems to itch alot during the evening hours into the early morning. We have tried several shampoo's and conditioners and am now using a hypoallergenic shampoo called "efa HyLyt".It does not seem to have help too much. I have read in various books not to use oil on her and have been told by our vet not to use human shampoo. Her skin looks fine, she does not have any bald spots and changing foods did not seem to make a difference. Does anyone have any recommendations?
