What has made my dogs skin and coat beautiful is a daily combination of 1/2 tsp of ACV mixed in some plain organic yogurt. I use "nancy"s". My big dog- black lab mix has yeast issues in his ears and paws and it has cured this problem but also improved his coat as well as the coat of my other dog. I see huge skin improvemnets. It took about a month to see the difference as I think it changed the PH of his gut thus working it's way out to the skin. I got a little lax on the routine and right away notice the old problems back. Needless to say I am going to do this everyday from now on. One more thing- my dog with the yeast problem has been allergy tested and has a dairy allergy- I figured I would take a chance with the organic yogurt and I have seen NO ill effects- it is full of all the good bacteria- not sure if that made the difference or what.
