my yorkie was about 3 yo when she started having a similar problem, first was told not too worry, then that it was allergies. she eventually was treated for thyroid and was put on a home cooked diet. i choose to believe she found some level of comfort. She tried Atopica, which didn't really work. I don't believe it helps the immune system bit rather supresses it. Atopica is the canine version of what they give humans after an organ transplant to prevent rejection (by suppressing their immune system) Actually the canine version wasn't avaiable in canada at the time so i actually had to buy humane medicine at shoppers drug mart for my dog. i wish you all the best and hope you have a better outcome |
