So we tried switching our puppy's dog food to Blue Buffalo, (we did it very very slowly) but right away he had severe diarrhea and we called the vet and they said it might be just the food not reacting well to his body. It's a very very rich food!

Well we bought a 30 lb bag of this food!! It's opened and in an air tight plastic container. I tried contacting out local Humane Society, but they can't take it because the bag is opened.

Any other ideas of what I should do with it??

It would break my heart to throw out all of this perfectly good food! Plus its pretty high quality (the bag was $60!!)

I'm not looking to get money back from it, I just don't want it to be wasted.

Any ideas?
