I'm a big promoter of natural foods. I got started on it because one of my dogs has a corn/by-product allergy and stuck with it because I was impressed with the difference I saw in the dogs' coat/shedding/pooping. I run a small pit bull rescue and try to feed the dogs the best food that I can afford. I tried BB lamb & rice because a) it seemed like a good food and b) it was on sale. The dogs eat all of it enthusiastically, but then again, anyone who knows pit bulls knows that they will eat just about anything (my game-bred foster female eats bugs). Their coats are still sleek and shiny and they shed very little. However, they have been having the worst gas I have ever encountered. I know bull-dogs are prone to flatulence, but I swear I can SEE the gas clouds! Also, my 2 year-old 65lb male has been experiencing some vomiting and loose stools. I suspect it may be a reaction to the lamb since previously the foods I was feeding were chicken, duck or venison protein based, but I am not going to blame BB since I don't know for sure. I believe that BB is good enough to give it a shot, and if it works, stick with it. If it doesn't work for your dog, try something else. I work at a large chain pet store and we offer a 100% satisfaction guarantee on pet food... if the dog doesn't like it or doesn't do well on it, take it back and try something else.
