        PERFECT FOR MY PUP
        Color: Beau - The Teddy Bear​, Size: One Size
        I purchased this toy for my two month old golden retriever pup! To be honest, I originally purchased based on looks (I thought it matched my 'vibe' well) but it has ended up being one of my pups favorite toys!! I also purchased the rabbit! She absolutely loves chewing and snuggling with these toys. They have held up well throughout the shark phase of puppyhood LOL! Would definitely purchase again!

        My dog loves them!
        Color: Bear Bunny Elephant without Basket, Size: One Size, Color: Bear Bunny Elephant without Basket, Size: One Size
        I got these for my dog’s birthday. He absolutely loved them! I’ve been trying to stay away from synthetic fabrics and I was so happy to find these well made dog toys. They don’t really squeak but are heavy and sturdy feeling. They are also a pretty decent size so that they suitable for my 80lb pitbull. They are not machine washable. Overall I would recommend.

        NOT durable (tested by a french bulldog who is not a super chewer)
        Color: Beau - The Teddy Bear​, Size: One Size
        This bear came apart in less than 2 minutes (french bull dog, playing by himself, and not a super chewer) - so I would not consider it durable; and this isn't a fluke, as it's the second one we've tried. We purchased it because we have a Pet Passion Plush Rabbit - which has proven to be durable and has stayed together beautifully - so we do recommend the rabbit. Same dog, same play behavior with both - so it appears the bear is not crafted the same as the rabbit.
