My dog is crated as well...
the rescue place we got him from crated him for like, 8hrs a day, so he was used to it (as terrible as that sounds)
My puppy does just fine in his crate...he barks right when you leave him, but only for a minute, and then sleeps all day, lol
we just cant trust him to be alone and hurt himself, or destroy the house...
plus, he wont play by himself anyways...or at least he wont eat kongs or anything...i cant really tell if he plays with toys
We did just get an outdoor kennel for him, which is a pretty good size for him...the neighbors donated it to us (yay for free stuff) after both their hunting doggies died.
Could you get an outdoor kennel?
