But without their own space, puppies lose their sense of self. Everything becomes about you. And woe to you and your home if you happen to leave your dog alone.
There is, however, a way you can bend the rules a little - to at least get in your cuddle time, which is vital to puppy and human alike.
"What I would do is I'd have the puppy in the crate overnight and then wake up early in the morning and then take the puppy out to go potty," Kover says. "And then snuggle with the puppy in the bed. So you still have that snuggle time. Because that's important, too."
There are a few other reasons why puppies should get used to a crate early on. For one thing, there's safety.
"You need to use caution that you don't roll over and squish them because they are so tiny," Sonja Olson, an emergency clinician at BluePearl Veterinary Partners, tells The Dodo.
