If you're looking for a quick snack but you can't find a real dog on the shelf, there are plenty of creative ways to add a bite-size puppy to your dog's diet. One of the most popular options is canned dogs; your dog can take a little food and chew on it and get as much nutrition as they want. You can also try the "chewable dog" formula, which uses only the food you choose. As long as your dog consumes the food, they'll need to keep on eating it. But if you have a stubborn child, or don't want to spend time trying to teach a puppy to eat human food, there are lots of "diet choices" around for little humans who want to go on a dog's diet. Puppies Are Different When you look at a puppy, it's important not to confuse "dog" breeds with "puppy." Puppies differ from adult dogs a lot. Puppies will look the same but have different behaviors, such as biting, self-humping and even rolling on their stomachs or lolling on the table.
