I have a 10 year old yorkie. I give him a teaspoon of kefir and plain yogurt with his meal. I also give him prozyme enzyme and Mercola’s probiotic. I give him the enzyme and probiotic 3 times a week. He gets the kefir every night(he loves it yuck) Am I doing too much? I am out of prozyme any ideas for digestive enzyme? He doesn’t do well on Mercola’s. Thank you.
