So I'm leaving on vacation on Thursday and my cousin is going to be dogsitting. They have enough food to last through Saturday, so I want to make sure I get another bag before hand, naturally. I have been to all the PetSmart's and PetCo's in our county and I can not find their food. I have always fed them Nature's Recipe Easy to Digest Fish and Potato. Well, they all have the Nature's Recipe Easy to Digest, but it's the Chicken, Rice, and Barley flavor. I really have no choice but to buy the Chicken flavor, but what concerns me is Chip and Smokey have really sensitive stomachs and I don't want them sick while I'm gone. Would it hurt them to change flavors or will they be okay? I do have some anti-diarrhea medicine that my cousin can give them just in case. Any ideas? Suggestions? I have to buy them a new bag tomorrow afternoon.
