Brodie had a crate up until she was about a year old, it was her den and 'safe area' and she used to love going into it if she wanted some space. She was crated whenever she was left alone (which was never for very long) and at night, so I knew she was safe and would come to no harm, plus there was no chance of her chewing things she wasn't meant to
. Once she grew older she stopped using it so much and preferred to sleep on the sofa, so we decided to get rid of it - however I know of plenty of dogs who still use and love their crates, no matter their age
