Thanks for all of the replies. No, we don't crate him at night (we tried the first night, and he barked and whined, then the other 2 barked--whew). He lays right on one of the beds or on the floor with Abbey and Kito. It's just when I need to go somewhere, and I don't want him running around the house. Kito and Abbey have a HUGE pen in the basement, carpeted and everything--they love it--they don't even come out when we come home!! We tried keeping him in there, but it's too big, he had accidents, and stuff got eaten, a big gross mess!!
He went in willingly today, because he could see the kong, and we've been feeding him near it. We're also trying not to get him out while he is whining or crying.
Rachel, I will pm you, it sounds like a good thing to read!!
