I've been feeding my dogs Chicken Soup for the Dog Lovers Soul since I discovered it in 2006, Its always been great for my dogs, between my Dobes, my greyhound, the beagle, the min pin and all the foster dogs its always been fantastic. My dogs have always had beautiful thick shiny coats and bright eyes and clean teeth. My Greyhound has had some food allergy issues, but the large breed formula usually treats her well, especially since I combine it with 2 tablespoons of whole fat yogurt and fish oil.... But Maybe May, she's been having a tough time with her food. We've used the Nutro Natural Choice Sensitive Stomach and it was the worst diarrhea I've ever seen a pup have, We tried Halo Puppy Formula and she refused to eat it, and of course Chicken soup for puppies, and for large breed puppies... She loves the Large Breed food, but her poops are very soft. I'm just trying to figure out a great Sensitive Stomach food that isn't ridiculously expensive, and is going to give her the vitamins and nutrition she needs while having limited ingredients for her tummy. Any suggestions??
