I recently got a pomapoo who is now 5 months. He came from the breeder on Purina Puppy Chow and I have been trying to gradually wean him off of that and onto Wellness Toy Puppy formula but he picks out the puppy chow and eats that. His big brother, my 3yr old, 96 lb lab, eats Kirklands, lamb and rice and the little guy really fights to get at the Kirkland food. I am thinking about switching to an ALS formula that they can both eat. The little guy seems to have a sensitive stomach. He gets diarrhea pretty easily. It would be easier if they both ate the same thing and if it were a quality food. I am not sure if ALS are right for tiny toy dogs (2.3lb). Any suggestions would be appreciated.
