Hi Brian, the problem we had with my two boys was not colitis, but my vet here in Italy (he is professor at the University of Perugia told us that he had been working on a research showing that any pet food formula that includes meat obtained by intensive farming, contains a residue that can really harm pets. If you have the possibility, try and feed your dog with homemade puppy recipes for a few days, if this is the case, you should see improvements within a week. Good luck!
