I know this sounds crazy but Lucy has had a complete personality change after being spayed. Is this normal? At first I thought it was from being so confined for a week and she was feeling better after the surgery and infection but her behavior just gets worst. She is not listening, acting very hyper, and even barking in her crate which she never did before. She always settled down when she was in her crate and never even whined. Is there a hormone change causing this and will it go away? Today was horrible with her either in her crate barking and whining or running and jumping out of control. I hope this is a short term side affect from being spayed.
