Put your aggressive Chewer dog to the test!
Color: A Red, Size: For Larege Dogs
A very tough toy to stand up to my aggressive chewer lab! It's a great value! The squeak is not annoying, and she's got to clamp down hard on it. It's a nice throw toy! It bounces once or twice but it still brings out the pup in our Dog! Not too small a nice size for a Lab or retriever

A Hardy Toy for Chewers
Color: Bule Octopus, Size: For Larege Dogs, Color: Bule Octopus, Size: For Larege Dogs
I must say I was very surprised with the durability of this toy. We've had it for 3 days and not one puncture hole. My rescue is a destroy chewer that doesn't care for Hardy chew toys unless it squeaks. While the squeaker isn't the best, he still loves it. We put peanut butter in the grooves for him and he goes to town. Will purchase again should he ever destroys it, worth the price!

Durable toy for a great price! Will buy again.
Color: A Red, Size: For Larege Dogs, Color: A Red, Size: For Larege Dogs
Great toy, heavy, good size, and durable for active chewers. My two dogs like to play tug a war a lot and this toy has held up fantastically! Afterwards they tend to chew toys to pieces but this one has stood the test of time so far. Great buy!

Very tough & VERY heavy
Color: A Red, Size: For Larege Dogs
My dog is a half black lab/half pittie & a very aggressive chewer she goes through toy bones very quickly, to the point they're so slivered up within 2 days, sometimes slightly longer, I have to get rid of them, they never last long, except for whole antlers and some split antlers. Although she rarely touches the whole antlers . Anyways, this is a great tough toy for strong large breeds. It squeaks in the center if you squeeze hard enough but the toy/bone was a bit too heavy for my girl. I got her the next smaller one and she still plays with the big heavier one more than the one that fits her perfectly so go figure. It's a great product and definitely recommend for heavy chewers. I only took a star off because of the weight I was extremely surprised by how heavy it was, but that's not necessarily a bad thing depending on the dog, this size is just not for my dog. I think I've had it about a month and she does play with it, not as much as her other toys, but it's still in amazing shape even with her heavy chewing.
