Dog likes it, but is very hard material around smaller dogs when he is playing and running
Color: Blue
My 22lb dog loves this chew. We have owned it just for one day. He immediately loved it and he races through the house holding it in his mouth like a grand prize. I have concerns to the hardness of the ends of it, the material is very hard, and the tail comes to an end shape that could hurt other pets in a multidog home if it hit or stuck in them. I have two smaller chihuahua dogs, one who has lost an eye so this is something to be careful about with other dogs running with this toy. This may not affect a one dog home. Best to observe the dog while playing with it around others.

Strong and holds up to aggressive chewing
Color: Blue, Color: Blue
This was a fast favorite for our extremely aggressive chewer ('indestructible' toys are typically destroyed within hours)... this has survived about a week and still going strong.

My dog is a very aggressive chewer.
Color: Blue
My dog is an aggressive chewer and this lasted about 3 weeks before he started to get into the plastic and I had to throw away. It lasted longer than other chew toys so it was good. However the tail makes it easier for him to chew off into pieces. He gets nervous and needs to chew on something. I find the hard cheese sticks a better option for his nervousness.

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! 🐶

LOVE this tough toy! My teething puppy is still enjoying it!
Color: Hedgehog
LOVE the hedgehog! Very tough! My dachshund has not been able to chew off any of the 'nubs', and does she try! lol The only thing is, the first thing she did was chew off the nose, but I discarded it and watched her closely to make sure she didn't chew off any more, and no, its still being chewed on. Wish I could find more toys like this one!!
