Durable chew toy.
Color: Blue
My dog loves these. She chews on them a lot. She seems to like the different shapes. She is part Pit and an aggressive chewer. These chew toys last a long time. And I love the three pack so if we lose one, we always have a spare.

Decent durability for the price
Color: Blue
Bought a bunch of these for a dog shelter and have to say - decent for the price of you have aggressive chewers. All of the toys are still going 6+ months later, even with the strongest jawed pitty mix. Does get torn up at the ends but can easily be sanded down for a longer lasting toy, unlike some other hard toys with material not meant for sanding. The antler and ring seem to be favorites. The antler even has a divot so you can put soft treats in it or peanut butter and freeze it for a more interactive experience. Some came with a strong beef/liver smell but not overwhelming or off-putting. They are hefty without being too heavy, less likely to damage floors. Overall a good purchase

For aggressive chewers
Color: Blue
My pup is an aggressive chewer and these keep him occupied. He keeps coming back for them. Go to replaced old chew toys. Only issue is he leaves his toys everywhere and if you step on them. They are quite sharp

Not the best for REAL CHEWERS.
Color: Blue
My dogs love to chew and these didn’t last too long. It did keep them busy and I probably will buy these again but don’t expect much resistance of yours have big dogs that love to chew toys.
