OK, Malone REALLY loves these nasty dried animal parts, but I think they REALLY stink!!! We've tried hooves (Ucccck!); pig ears (the smoked ones aren't AS bad, but it still made my kitchen smell like a barnyard); a snout; a bull stick (ewwwwww!). I wish so much(!) that rawhide was a safe thing because it's the only thing that doesn't stink to high heavens. We will give him a pig ear just before we leave so that he isn't as anxious.
