I am fighting liver damage..call your vet and ask just to be safe!! if any toxins have gotten into your babies system, you need to get some milk thistle in her/his system to cleanese it, I have my 9 year old on it and a liver repair diet trying to save his liver and life, don't know what damaged his liver, but know that paint will damage a liver of a little yorkie, so read up on every website you can, and stay away from the liquid tick and flea crap you put on the back of dogs, it is poison that builds up in the blood system and damages the liver, use the pill form that guards against heartworm, flea and tick. Hope this helps... Write me at colorirstkim at hot mail dot com if you need me.. I am a yorkie nut...
