My baby is 9 weeks old. I got him 9 days ago and he was eating Diamond Puppy Food. I heard that this was not a good food so a couple of days after I got him, I switched him to Natural Balance. For the first 2 or 3 days I mixed some of his old food with his new food and now I'm giving only his new food. He has been eating and drinking really well and seems to have a lot of energy but for the last 3 to 4 days he has been pooping 6 or 7 times a day. It is not watery but is really soft and yellow in color. Is this normal? Do I need to change his food again? Does he need to see a vet? Please help!!
