    Good quality.
    Color: Pink, Size: Small（6Pack）
    The new toy poodle puppy loved all the toys. Perfect size for a very small dog.

    Love them
    Color: Pink, Size: Small（6Pack）
    Both of my dogs love chewing on this toy. In fact, I had to order a second one because they kept fighting over the first! It has definitely been a big hit with both of them. I have a Boston Terrier mix and Shitzu.

    Cute but not for a strong chewer
    Color: Pink, Size: Small（6Pack）, Color: Pink, Size: Small（6Pack）
    My puppy loves all of these toys, as those one of my older dogs. They are adorable and a good size for a small medium puppy. I recommend them, but they can chew some of the small pieces/nubs/ends so just be careful.

    Perfect for Aggressive Chewers
    Color: Blue-Green-Orange
    I've been looking for toys my German Shepherd puppies can't tear apart or chew into little bits within minutes. These are tough enough to stand up to them and have the added benefit of helping their teeth with the little surface nubs. This is the second set I've purchased - not because the puppies destroyed them, but because they needed a set for inside as well as outside. I HIGHLY recommend these toys if your dog is a destruction machine!!

    Durable, sensory texture
    Color: Blue-Green-Orange
    These are fantastic. They are durable and high quality. My dog loves the sensory texture and they satisfy his aggressive chewing. I've bought other high-end, popular brands and he chewed through it in less than two hours. I would definitely buy these again (if I even had to)!
