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.

From Puppy Teething to Adult Favorite – 7 Years Later
Color: Teething Stick, Color: Teething Stick
This has been one of the best toys I’ve ever bought! My dog has loved the Pupstages Cool Teething Stick since she was a tiny puppy, and now at 7 years old, it’s still one of her absolute favorites. It’s been amazing for soothing teething when she was little, and now she still enjoys chewing on it and carrying it around. It’s held up surprisingly well over the years, especially considering how much use it’s gotten. I also love that you can cool it for extra relief—it really helped during those puppy stages. If you’re looking for a toy that lasts and actually becomes a long-term favorite, this is definitely it. Highly recommend for both puppies and even older dogs who still love a good chew! 🐶
