What brand food to you feed your dogs? Gracie started out on Iam's Active Puppy, switched her to Wellness Core - gave her awful gas and then we switched her to Solid Gold. They have changed the formula on it also. She has had gas with that and full anal glands. My vet said to switch again and said that gas was not a good sign. She recommended Merrick, Nature's Variety, California Natural and Taste of the Wild. I know you can't just change over night. I was almost out of Solid Gold so I had to buy a small bag. I went to one pet food place and they had some samples for me to try. There are so many different types of flavors for each. I think Gracie will eat just about anything! I don't know how to try things out with the small little bags! I don't want to upset her little wild Indian tummy! :)
