I hate to "push" this nutritionist I'm using, but she apparently does work wonders w/ allergy dogs (and cats). She worked miracles w/ my Marcel's ibd/ibs, that is for sure. I'll link you to the "illnesses page" and you can click from there. I highly recommend her, BEST money I ever spent on Marcel...after hundreds at the vet, argh!
