yes it will grow back but can take time. I think took my boy a few months to grow back. Just keep it clean if it exposed , not alot you can really do to it. the only thing I noticed was when it was just starting to grow back my boy started chewing on it and kind of keeping it from growing. I had to keep on him and we used alot of bitter apple spray and had to distract him from it so It could come in. So just watch him.
