Squash LOVES bananas. If he's buzzing around being annoying and I don't have or don't want to give him a bully stick or recreational bone, I give him a banana with the peel on and it keeps him busy for awhile.
Kabota is neutral on bananas, but he loves watermelons. I knew he and my MIL had something special when I found out she was sharing her watermelon with him. (She won't share watermelon with her children.)
