We went to a local dog Barkery on Saturday. Turns out, there is a new owner. SHE's A SHELTIE LADY!!! She has four of them. So, of course, she was in love with Cooper and Rocket. She had purchased several antlers to sell at the shop. We bought some. She said, "Tell me how the dogs like them because mine don't like them." Well, our shelties don't seem to know what to do with them either. BUT- the cats LOVE them. They knock those things all over the floor for hours. So, the Super Shelties official opinion on antlers is that they are terrible chew toys- but make EXCELLENT cat toys. LOL!!!
