Puppy loves it!
Size: 6 Inch, Color: Bone
I have a very energetic lab puppy - this chew kept her still for longer than any other toy I’ve tried (besides bully sticks and peanut butter). Highly recommend!

Good for an aggressive chewer
Size: 6 Inch, Color: Bone
My dog loves it. These last a long time. My dog is a Rottweiler/American Bulldog mix, she goes through a lot of toys. So, I try to buy her something that has no stuffing, but will keep her from getting bored. This one has lasted about 6-7 months, the leather is chewed off, but it's still the shape of a bone. I did just order another though, the one she has is a little stinky from her slobber. :-)

Not as expected
Size: 6 Inch, Color: Bone
I have been looking for these ever since we got a similar one at Sierras for our 1 1/2 yo Cane Corso. She is brutal on chew toys and the first one from the box store held up well. However, this did not hold up as well and she was done with it in less than a week. Still looking for that perfect toy.

More durable than expected.
Size: 5 Inch, Color: Raccoon
I was walking through my front room the other day when I noticed a suspicious spot on the floor. It looked like something I should not touch without gloves. As I got closer, I realized what it was. It’s the ‘guts’ from this toy. My dogs (Pit Bull and German Shorthaired Pointer) were each given one. Both are aggressive chewers with their toys. They ATE the faces off these toys and now play with the felt interior. I’m still trying to figure out how they ate through leather while the felt remained intact. Regardless, they still play with them. Now they are basically semi-fuzzy throw toys we can throw in the house because they don’t leave marks on the wall if our aim is off. Sometimes things work out the way they should. :)

Great with supervision
Size: 6 Inch, Color: Bone
My dogs LOVE these, but removing a star because these apparently are VERY delicious and they will ingest what they rip off if I don’t supervise; also removing a star for how quick they’re able to tear these up. These are like catnip for dogs, I’ll still buy them!
