I also use Blue Buffalo Wilderness Puppy for my Miniature Rat-Jack-Chi (maybe, not exactly sure what he is, but he looks like a mix of these 3 breeds (Miniature Rat Terrier, short-legged Jack Russell, possibly Deer Chihuahua) somehow), currently mixed with Vet’s Choice Holistic Health Extension Original. I have already purchased his next food batch – Dr. Tim’s Kinesis Grain Free (15 lbs) and Nutrisca Chicken and Chickpea (also Grain Free) – 4 lbs.
Like everyone said, if you rotate the food brands, and also vary the proteins within a brand, your dog should be fine. Every few months is what I will be doing – basically when my batch is up, my dog gets a new mix of 2 different brands.
