Lucia,
I know nothing about large breed puppy food but I’d choose a food from HDM’s list and feed it. Add a probiotic. Do a very slow transition over a week. Keep him on this food for a couple months, at least. If you want to try another food, repeat.
Ashlee,
somewhere in this thread is a link to the list of approved large breed puppy foods. HoundDpgMom compiled the list; she has bloodhounds too. You’d do well to feed a food from this list. I have a hound named Boone too! He’s the pbgv in my photo here!
