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.

Theething toys for puppies
Color: Yellow, Size: X-Small（9Pack）
Good selection of teething toys! One squeaking ball, 4 different 'bone' type chews and a ring with a cloth attached. Lightweight, durable and sturdy. The Squeakys doesn't last long in this house but the ball is still intact,so far!! I definitely recommend these. Great value too!!
