lets see... as I dig into my feeble mind to try and remember....
Since he was rescued in December....
Innova
Wellness (I think)
Blackwood (he did well on this but I wasn't comfortable with the extra fillers, etc...)
Canidae
His reactions to the foods are loose poops... he does well for a few weeks (though poops are never rock solid, so to speak) and then it's back to yellow/orange loose, runny poops. The only food he did well on was Blackwood's lamb/rice.... and of all listed that is the only lamb/rice tried.
Riley has been eating rice made with chicken broth for the past couple days....
I hope this extra info helps.
