I'm concerned with my pup's sleeping patterns too. When we first got Wall-E at 11 weeks, he would sit quiety in his bed all day and sleep all the time... we didn't know if that was normal or if he was depressed from being taken away from his mother
and sibling... but now he is more active. The only thing is that I think he sleeps during the day while we are at work and is up ALL night wanting to play, but since we're sleeping he just sits quietly in his pen. I'm a little worried...
Anyway, are you home all day with your pup? Or is he home alone?
