Tylan Powder (med. from the Vet) is what was TJ's magic cure!
While we were doing the 'strict' diet to see if it was food related...
IVD - Duck and Potato (I hate the ingreds. and crap they put in here) so after the first bag was finished I switch to Natural Balance - Duck and Potato.
BUT, the real cure for TJ was the Tylan Powder prescribed by my Vet.
NO MORE TUMMY TROUBLES for TJ and he can eat whatever
