You’ll want to crate your puppy when you’re not at home to keep him out of trouble and make him feel safe while you’re away. Your Dog Carrier or crate should be tall enough so that your dogs’ back touches the top. It should be long enough that he doesn’t have to curl up to sleep. According to Dr. Nick Dodman, a Veternarian, larger dog carriers or crates do not seem to provide the same security. You want your pet to feel safe and secure while you’re not at home or while he is traveling in the car with you. If your crate is too big for your young puppy, fill the extra space with a box until your puppy grows. Remember, “Bigger is not always better.”
