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.

Maybe not for super aggressive chewers
Color: A Violet, Size: For Larege Dogs, Color: A Violet, Size: For Larege Dogs
I had high hopes for this toy, I was so excited about it. I have aggressive chewers, two Malinois/Dutch Shepard mixes and a Pit. The Shepard's chewed pieces off of it in literally 5 minutes. At the ends there is a small lip and that's where they started chewing pieces off. I had ordered a second one before I gave them this one (early Christmas present) because when I received it I noticed it felt very sturdy and durable. They do like it so since they already chewed this one I'm going to see if I can shave that lip off and maybe they won't get anymore pieces off. That'll decide if I return the one that arrives tomorrow. Maybe not good for super aggressive chewers. It's very thick and seems well made. Might just be better for other dogs.

Fantastic for rough chewing
Color: Bule 0, Size: For Larege Dogs
Our big boy is rough with his toys and always seems to disintegrate his toys in seconds. I had seen this with hoping this will be the toy he doesn’t destroy. On day 2 now with the toy and he’s obsessed, even feel asleep with the toy in his mouth and still in one piece. Highly recommended for tough chewers.

Good but not for my dog
Color: A Red, Size: For Larege Dogs
Dog loves it but already falling apart. Can't seem to find a truly safe dog toy that won't come apart with my aggressive chewer. Had to toss it before pieces got ingested. But great toy in the begining. Just not safe for pit/staff type dog that destroy and chew.
