I have a new whippet pup who is now 12 weeks old. She used to use a soft crate to sleep in when we first bought her home however has now outgrown this. I am seeking advice on soft crate v wire crate and also what size so I will not have to purchase another when she is fully grown. We currently have her in an open pillow type bedding and she seemed to settle more when she had a roof over her head in the soft crate although she does sleep inside the house anyway. Any advice please.
