Hi all! One of my clients has 2 yorkies, brother and sister. The girl has doubled her weight in the last 6 months from 3 lbs to almost 6 lbs. We had her checked at my vet's office along with the yearly shots etc. and had her thyroid levels checked which was expensive ($160) and came back normal. She eats very little and my vet didn't have any ideas.
Any thoughts? Thanks in advance.
