Our Pup's New Favorite!
Style: Rabbit
This is my 2 year old Golden Retriever's new favorite toy! She was confused, at first, with why the carrot was lumpy, but when she discovered some little bunny ears poking out of the hole, she got excited and got to work. She loves pulling out her "babies," and any other smaller toys we put in there for her. The bunnies have become a favorite toy on their own, too, and she carries them around, and loves to hand them to us and look expectantly while we admire her "baby." <3 She's still young, so has pulled at the carrot quite a bit, but hasn't destroyed it. I'm pleasantly surprised by the durability so far!
