its been ongoing since we got her, well it is sort of an intermittent problem. It comes and goes. I dont think it has ever been cleared up entirely..... I will try the vinegar / water rinse. I have been feeding her the same food but its 3 different kinds, buffalo blue -fish and sweet pototoes, buffalo blue- lamb and rice, natures recipe - chicken and rice. I sort of mix them a little bit. This is what they were feeding when I got her. One of the dogs in the foster situation had all fish diet, and they mixed some in with hers too. they said it made for better digestion and smaller poops. Her Treats are Newman's Own, Talk to Me- cheese flavor, and Milk Bone for small dogs.
