I just have a couple questions
when she had the kibble did she choke while eating it
When you fed her was it gone in 10 or 15 min.
Also Important to feed a quality food not something from the grocery store but a pet shop. We can give you some ideas on quality food if you think that might be the problem. If you do change food be sure to do it gradually by adding a little of the new each day and taking away some of the old until it is all new.
A thin yorkie always (one where you can feel their ribs)always makes me think of liver shunt and maybe should be tested for it. Your vet will give you more information and tell you if he thinks that could be the problem. If you google 'liver shunt' you can read about it and I think get info by a 'liver shunt in yorkshire terrier' google also. She could be just so full of energy or have a thyroid problem.
Good Luck and keep us updated. Joan |
