Hershey - the KONG destroyer - just got herself a nice big deer antler to play with. In 20 minutes, she was eating tiny pieces of it, scraping them off with her teeth. Is this normal? She hasn't broke a chunk off or anything, and there's nothing she could choke on.... Are they meant to be eaten?
A couple of Holistic type pet stores here also as well as a chain called Red Bandanna. There are several places online where you can order; just google and you should be able to find them. I like to buy them locally as we are picky about the size and shape.
