I have a 4 year old Jack Russell Terrier who recently had surgery because of a diaphragmatic hernia and the vet told us to keep her in a crate for 2 weeks at least so that she doesn't accidently pull the stitches out. It's been a few days, and by now, the stitches arn't tender and she feels fine.

When I left the house to go for a walk, she somehow burst out of the cage. Thankfully, she didn't do any damage to her stitches.

She cries and tries to escape from the crate whenever she is left in the room alone. She feels better and doesn't understand why she must stay in her crate all day. What can I do to make her happier, but still keep her out of trouble?
