I was at the vets this morning and we were talking about diet, I told him that I give Blitz a teaspoon of probiotic yougert everyday and he told me that dairy is not good for dogs and I should instead give her this (Prostora) as it a beneficial bacteria for dogs and contains no dairy. My vet is a friend of mine and has never sold me something just to sell it, but my only concern is this is a manufactured product as apposed to organic yougert that I have been using. Has anyone used this before or have any thoughts on the no dairy thing....
