Bella, our 18 month old yellow Lab, ADORES seedless watermelon. It's her favorite hot weather treat! The silly thing will sit there whining and pacing until you hold a wedge of watermelon for her to dig into. She got the idea really fast to only eat the red part. I'm amazed at how exact she can chew all of the red but never any of the white or the green rind.

Oddly enough she loves bananas too! LOL (she's a Labrador so I guess nothing is "odd" to eat for her )
