Best chew toy we have ever purchased.
Flavor Name: Classic, Size: Large
My moderately active 80lb Lab - Pit mix has been steadily working on this bone for over a year. He doesnt chew it every day but he does regularly chew it for 30 or more minutes at a time. He has only been chewing on the smooth end, and the only wear it shows is a slight thinning and some grooved tooth marks. It has not had any chunks come off, and has never developed any sharp edges that make it hard to play with.
It has never smelled or gotten slimy. It has never triggered resource guarding with him, but he likes it enough that presenting it to him will often get him to settle down and chew when he is in a rambunctious mood. Its size and shape allows him to hold the textured Y end with his paws while chewing on the smooth end.
All in all a fantastic toy!

Happy Doggo
Flavor Name: Beef, Size: Small
He immediately loved it. He doesn't take to bones quickly, but this one caught his eye. He's a 35 lb shepherd mix, and loves antlers, and chews pretty hard. I love that it doesn't smell, and havne't seen or noticed flakes. Overall would recommend.

Excellent product, highly recommend
Flavor Name: Classic, Size: Large, Flavor Name: Classic, Size: Large
So glad I came across this brand that uses actual edible material instead of the plastic nylon! All of our dogs love the nylon chew toys, but it's so bad for them to eat the little plastic bits! I got the large one & it is VERY large! I actually wish they had a medium one, one in-between the large & small ones as an option. But our dogs still love the large one, just harder for them to carry around & boy is it loud each time it gets dropped on the hardwood floor. It's big enough both the pups can chew on it together at the same time & do just that. We've had it for a couple months now & they don't chew on it everyday, but a few times a week I'd say & it's a tad bit softer than the nylon chews, but I'd say it's held up very well!
