How safe is rawhide? I bought some at the Petco clearance bin to see if Nebo would eat it or not (Smokey and Reggie have never really liked it) One is a bigger dental bone, and I have a package of smaller cheese flavorted twists. He *loves* those cheesy ones....it's very nice because it keeps him occupied for a long time, lol. I haven't let him chew on them alone, just giving him one in the kitchen while I do other things. I swear I have heard that rawhide can be dangerous, so I'd like to know if you guys have any info on this. Thanks.
