My vet said that most yogurts and probiotics for humans do not contain Enterococcus faecium, which is one of the main ingredients in probiotics made specifically for animals. She said that E. faecium is what makes the probiotic beneficial for dogs, yogurt is just a treat. There are some makers of human probiotics that put E. faecium in them, I think most of them you have to order online.
