Hi-
A great resource for me when I was having smiler issues was http://www.dogaware.com. They have some wonderful advise for digestive disorders. It turns out that mine had both giardia and coccidia and have struggled with loose stools off and on since.
Have you tried to feed them small meals of boiled chicken or burger with overcooked rice and pumpkin yet? I usually try that for a couple of meals and then add back n kibble to rest their bellies a bit.
I rotate between Vetri-Pro BD, Perfect Form and Gastriplex to help with their loose stools. Check out that site. I believe it could have some beneficial advise. Good luck, you have your hands full!
