here is another thing to consider -- has your dog had bile acids done or blood work recently? because many yorkies have liver issues so any internal or external med gets into the blood stream and can affect them if they have a liver issue as the liver problem makes it harder to detox the body of the toxin so just a thought this could be a sign that your dog does not have 100% liver function. My dog has mvd so we have to be very careful of any meds due to this so just a thought to look into it the next time you do blood work if you have not had recently |
