Shannon, you have my sympathy as finding compatible food for the bully
is equal to having a pt-time job and sometimes, a full time gig! The protein
thing is confusing just like fats but lots of bullies do well w/the NVI Lamb.
Many bullies are allergic to salmon (chicken is also a big reaction) however,
those same bullies can very often do fine on raw salmon or chicken that is
w/out toxic preservatives & chemical additives. If the salmon makes him
vomit, I'd stop immediately instead of slow transition and just give lamb. It
will take about a month for old food to clear from his gut so don't panic yet.
Slippery Elm, found online or health food stores, is a natural herb that coats
the gut/intestines thereby soothing, calming & HEALING the gut, great stuff!
For people too, wonderful to keep handy for any tummy upset. I'd cut all treats
right now until you see how this food works or not. Good luck and let us know.
