Not my husky's favorite
Size: Large
No bounce, it's too hard and heavy. My husky only uses it once in a while, it is not his favorite thing to chew on.

Better Than Most, But Still No Match for My Super Chewer
This is a decent chew. It’s made of a softer rubber material and has little to no odor, which I appreciate. It’s been about a week, and while it’s still technically in one piece, it’s starting to show some cracks and tiny puncture holes. Now, keep in mind, my 100-lb pit mix Scooby Doo is a full on chew and destroy hound. If it can be chewed, he’ll find a way to shred it to bits. This toy held up longer than a lot of others but still didn’t make the “indestructible” cut in our house. He likes it, but it’s not his top pick, probably why it’s still alive. Overall, it’s a good toy for the price. Probably not for extreme power chewers like Scoob, but it’ll hold up fine for most dogs and give you a little peace and quiet for a while. Do give it a try, Scooby Doo is a chewer in a class of his own, the fact that this has held up past a one 15 minute session is amazing in itself.

Multifunctional dog toy, fetch, chew, dental health
This toy feels like soft rubber, unlike the super hard plastic Size wise, it would be a good toy to toss and play fetch with. My Aussiedoodle took to it right away. It has numerous nubs that are great for dental health. I use it, as well as other toys with nubs, to offer to my pups with a bit of smeared on it, to help with their dental health. 🤗 Thank you so much for taking the time to read this review, have a FANTASTIC day!!😊 5★

Not for aggressive chewers.
Size: Large
Our dog is a 50lb Pit mix. This toy lasted about a week before he took a hole knuckle off. Happy he did not swallow it.
