She walks right into her crate, before I've even had the chance to put down a blanket for her. Great, I think, she's OK with the crate. Once she comes out, I put down the blanket. She goes right in and promptly piddles on it.
Oh well, she'll learn. : )
ETA: Just put down towel and she promptly went in and peed again (with no warning sign). I think she might get a plain hard surface to sleep on for a bit.
She also appears to be a treat whore. I gave her a small treat when she went in to the crate and she promptly got really excited about the crate, going in and sniffing for more.
