Winter is coming on here in central Iowa and at some point we're going to have to put a bed in his crate so he will stay warm during the night; we keep the house at 58F during the night.
He was being a pest earlier so I decided to perform a social experiment with him, lock him in his crate with a polar fleece blanket, to see what his reaction would be. He did good, he spent a few minutes rearranging the blanket and proceeded to go to sleep. This is good because I was concerned about him shredding his new dog bed that I'll be making for him; basic polar fleece with polyfill inside to give him a couple of inches between him and the metal floor of the crate.
In case your worried about his being isolated during the day while in his crate, don't I'm a full five feet away from his crate working on the computer plus he won't be in there for long, during the day he spends anywhere from five minutes to four hours in there all depending on what errands I have to run.
I just wanted to see what his reaction was to the blanket, it took Angel a good five years before she would tolerate anything in her crate other than her food bowl, we'd give her a blanket and in the morning find it outside of her crate and her sleeping on her back legs straight up in the air! Now she sleeps on a polar fleece dog bed I made for her, again with the legs straight up in the air.
