Yup - some Pet Talkers thought I was crazy when I asked if their dog wanted my watermelon rind at the dog park. Many had never even heard of dogs liking them ... and it was about 50/50. Some dogs feigned interest until the realized what it was then left it on the floor, others just wolfed them down like they were meat! A good example pair - Cinder and Smokey. Smokey scarfed his down, Cinder just gave hers a cursory nibble and set it down.
