I just posted a question about our younger dog and his dislike of crate bedding. This post is also about crates, but about our older dog. He's eight, and he's never been a big fan of our younger dog, who is 3. For the past few months, when I tell them to go to bed, the older one has been following the younger one into his crate. Then they both just sit there and look at me. I don't know if they really want to sleep together, or if one has secret plans to murder the other. Any thoughts about this behavior?
