When Frankie started getting too agressive over the pillows and covers, we decided to make him sleep in the kennel. But he seems to like the kennel a thousand times better than the bed! ((I've climbed in there before and it was very nice lol)) Hes got 2 pillows, a fluffy seude bed with a soft comforter on top of that, and a blankie too. We also put a blanket over the kennel on cold nights It doesn't have to be a bad thing to kennel a dog at night, especially if your starting to have agression problems.
