When he was a pup he was on ol roy. I was to young at the time to buy anything or know there was even a bad or good dog food when I got old enough I switched him to chicken soup, then anther brand that i dont remember it was super high in chondroitin and glucosamine, but that didn't go well, then he was on EVO then I switched him to Blue, because he started getting diarrhea, then back to EVO because I realized he wasn't doing good because he doesn't do well with fish and I was feeding him the Salmon and herring EVO, then we were on EVO red meat after the blue and I just switched him t TOTW, because EVO was getting to expensive, so he has had a variation' of food, but not to much for being 17. This wasn't all back to back it was years in between.
He has had all kinds of pain meds for his arthritis and been on a bunch of different chondroitin and glucosimine some that were made for horses and such.
