Sorry to hijack an old thread, but I thought I'd add my 2c worth. I've have a 3 year old kelpie girl that has been to the vet with colitis / upset stomach almost every month since I got her about 6 months ago. We have tried feeding her just about everything, raw meaty bones, doggie chicken rolls, several dry foods but nothing helped her until I tried yogurt plus, she loves it and hasn't had an upset stomach since. Not sure how the yogurt culture survives the heat treatment, had wondered that myself.
