Great fit
Flavor Name: Peanut Butter, Size: X-Large
My dog has a very powerful jaw. Only a few things that he cannot destroy.
We have had the peanut butter flavor that still looks the same that it did a year and a half ago. It is his version of a binky. He may leave it alone for days or weeks but every so often he needs to have his teeth and gums itched.
Very few remnants of the bone left around.

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! 🐶

My puppy loves it
Color: Teething Stick
It's cute and a good size for my chihuahua puppy. It seems to be slightly tearing at the seam in the middle, but hopefully it will hold up.
