Our corgi is a very aggressive chewer but just doesn’t like this toy. He’ll pick it up excitedly and run off with it only to drop it and walk away, as if he tastes something bad. He’s attempted to chew it a few times but will stop within a few seconds and just walk away. He’s done this at least 10 times. I can’t figure it out. This dog chews up everything, but leaves this toy alone. I had such great hopes for this chew toy. A big waste of money.

One of my dog’s favorite toys! He destroys everything and is such a powerful chewer but this one lasted longer than any of his others and he really likes it!!! I bought another for back up so he doesn’t have to go without!

Great chewy!

Flavor Name: Bacon, Size: X-Large

Super durable chew toy! Our 9 month old golden retriever absolutely loves this thing. Even our 13 lbs malshi runs around with it! Great price for how well it’s holding up.
