Dog loves it! For tough chewers for sure
Size: Medium/Large, Color: Dog Ness Monster - Large, Size: Medium/Large, Color: Dog Ness Monster - Large
Dog absolutely loves it, he’s super rough on all of his toys they usually last about 10 minutes bore they are torn to shreds. It’s lasting through his chewing so I’m happy. It’s also super cute.

Cute toy, dog really likes it. I had my doubts when I pulled it out, and honestly so did she, but the soft part bounces, so that got her going. We've had it for about a week. My dog is ~70 lbs and a moderate chewer, and this monster still gets regular play and is holding up well.

Great toys for aggressive chewers
Size: Medium/Large, Color: Turkey Day Drumstick - Large
These are great toys they last a while they are destroyed after a while but both dogs are aggressive chewers but they last about a year and a half. And they are go to toys they have one that is a shark mouth and they love it I have bought 4. (two of them the pups lost ).

Durable and Fun, Just Gets a Bit Rough
Size: Medium/Large, Color: Chopper - Large
This is a really good toy overall, especially if you have dogs that love to chew. My dogs were immediately into it—they play with it nonstop, toss it around, and stay entertained for a while, which I love. It definitely holds up better than most toys we’ve tried. The only reason I’m giving it 4 stars instead of 5 is because over time it does start to fray a bit and gets a little rough, especially with heavy chewing. It’s not completely indestructible, but it still lasts longer than a lot of other toys. Overall, still a great buy and I would recommend it if your dogs need something tough but fun!
