I have one dog that requires extra enzymes or he has gas. If enzymes helped some, he may need a higher dose of them. If it is the canned food and you think it’s worse on Merrick, move on to a different one. Try going a few days without the canned and see if that helps. Kibble and canned foods, both, do not have enzymes in them, unless the kibble has them added back, because the way they are processed destroys the enzymes, and some dogs just do not produce enough on their own. It certainly can change over time, but no guarantees.
