Perfect for petite pooches!
Color: Blue, Size: Small（6Pack）
Perfect size for a petite pooch! My pooch loves the donut and the fish bones. Cute colors. She’s 9lbs and these are just the right size for her and appear durable. Easy to clean and just soft/hard enough to prevent tooth chips and to keep engaged.

Puppy loves the toy! Great deal and product.
Color: Pink, Size: Small（6Pack）
Say hi to Daisy- a13 week year old pit. She absolutely loves the toys! She was using another chew toy and DESTROYED it so I needed a quick replacement. They’re very durable; however, she chipped one of the bones so I don’t anticipate it having TOO long of a life. For the price, it’s great and I recommend for any chewers you might have.

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.
