Sam and I have a Jack Russel/Beagle mix. He's crate trained and we live in an apartment, he doesn't bark. He's a very smart dog, and we got him when he was 9 weeks old.

He won't be much bigger than about 20 lbs, and that suits us.

Crate training is a big one. It's a little frustrating at first for the first few weeks, but afterwards, its like their little home and as long as you keep it clean, comfortable and have toys in there for him/her, it won't mind going in there at all.

Dexter sleeps through the night in his crate, stays in there 8 hours a day when we're gone, rarely does he have accidents in it and when we're home, we give him lots of attention.

My experience anyway....
