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!

Don't waste your money!!
Size: 5 Inch, Color: Fox
With in minutes my puppy was pulling on the middle fiber stuff. I was worried he would choke/ingest it so I immediately threw it away just like the money I apparently threw away on this unsafe and misleading chew toy.

Durable!
Size: 5 Inch, Color: Raccoon
Love these toys/brand! Our Beagle had to have stomach surgery from ratting something he shouldn’t have. Since then we hit this brand of toy because he really can’t destroy it! Great quality and highly recommend for dogs that like to chew!
