Winnie has a very sensitive stomach and has gone through a lot of different types of puppy food before we finally found something that worked for her. I was just wondering if there is any place that I can donate the puppy food that she is unable to eat? I have some unopened stuff as well as giant bags that are opened but basically none of it has been used. I dont know if there are any rules or regulations in regards to this. Any help would be great, I just hate to waste so much food. I really wish they gave out sample sizes at stores to get before you purchase a whole bag, ugh.
