I'm sure the vet will have better ideas for you after observing her and getting her bloodwork back. I wanted to mention that I noticed in your post in general discussion that you feed them Eukenuba. Eukenuba isn't a quality dog food. I'm not saying this is causing the problem, but I'm sure it isn't helping either. There's a sticky at the top of the page with a list of good dog foods that don't contain a lot of fillers and other things that aren't good for your babies. Check it out.
You might ask the vet to advise you of the best way to switch thier food, so as not to cause G.I. upset.
I hope Jade is feeling better ASAP!!!
