My almost 8 week old puppy sleeps constantly! I know that puppies are babies and that they need a LOT of sleep. I'm just frequently surprised by how pooped she is after virtually no exercise or activity. Even first thing in the morning when she should have (or so I thought) pent up energy to burn, she still gets out of her crate, gets some water, has a pee and then sleeps around for ages. She is basically always laying down or sleeping. She'll play when we play with her, and once or twice a day she'll get pretty wound up (running, biting) for about 10 minutes. But other than that she's snoozing. Yes, I am a paranoid puppy mom! I know that! I'm sure this is perfectly normal, I just want to hear it from other people. Worst case scenario I'll just mention it to one of the vets at work and see if they have any concerns.
