I’m not sure the Purina would really help anything (It’s an awful food in my opinion)… I would put him back on the Fromms. The Fromms is at least a much better kibble and then add in a probiotic. I use the Mercola one’s but if price is an issue for you the Swanson one’s would definitely be cheaper per dose.
I heard you say he doesn’t like to eat sometimes, Hound Dog Mom suggested Trippet for my puppy when he was a picky eater. A couple spoonfuls and he was chowing down!
Vets really aren’t all that great when it comes to the nutritional requirements of a dog. If all else fails and you can’t get the yeast under control think about raw. I’ve heard many stories where feeding raw helped allergies, smelly dogs, yeasty dogs, ear infections, ect. Not that it fixes all problems but I believe what I read was that kibble is full of carbs that contribute to feeding the yeast.
