In the US, I suggest getting probiotics online from Swansons, I have no idea if they ship to Canada. But any from the health food store for humans will do. Sometimes they are touted as a digestive aid, so that would be where to look in any pharmacy type store. You can also try plain yogurt, though it doesn’t have very many strains, and the more strains the better. Look in the dairy case for kefir, it’s loaded with probiotics too. You can give about 1/4 cup daily.
