good purchase
Color: Red Nylon Yellow Hotdog
This thing is great for hi anxiety dogs and dogs that ned to have something to do or to chew. It will take them a while to get through to it. I was told that it was indestructible but I knew if there was a dog that could do it, it would be mine, and she did. But it took her some time. But she loves it and it keeps her busy.

Cute and durable!
Color: Red, Color: Red
My dog absolutely loves this toy! I'm not sure why people are complaining it's too hard, it's a nylon dog chew toy, it's supposed to be hard. I love the little holes in the lattice top I can stuff with treats. It keeps my very (VERY) active dog busy for a long time. I would definitely recommend this if you have a power chewer. It's also super cute, I just love to see him tote around a piece of pie.

Pretty Good
Color: Red Nylon Yellow Hotdog
The toy is good for a heavy chewer, but is very slippery. You may want to rough it up a bit before giving it to your dog so they can hold onto it.
