We just adopted the one ig in July and she was crate trained then.But she doesnt really use it now.We have two open crates in the house that they can sleep or hide in if needed and they do use them on occasion.Especially if they have bones and want to hide.
I dont know if I can get him to make them sleep at night in the crates.That is going to be very hard to hear them whine and its so cold and they love to curl up under the blanket right next to him.
But i know when he goes Im going to be paying the price.
