I have a beautiful 18 week old puppy that I am currently feeding Wellness puppy food to. I like his coat, and he his gaining weight nicely. My question is on his poop. When I take him out to relieve himself, he'll poop once. It's not a lot and is moist but firm so to speak. He'll then poop again before we come back inside, this time it's a little more loose. He'll then poop for a third time like if he's bored. This time it's like soft ice cream (Not to disgust those of you reading this.) Should I change his puppy food? Has anyone had this type of problem before? Is it something I should even address? Any suggestions?
