Weird to humans, amazing to dogs!
Size: Large (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
I find these expensive and weird, and yet I'm not the one chewing them and both of my dogs disagree. They feel they are amazing and tasty! They love to chew on these, and chew, and chew. Who am I to argue?

Defective cracked
Size: Large (Pack of 3), Color: Orange, Green & Yellow, Pattern Name: Dog
The stuff inside was cracked. It took my dog a few minutes to get it out.
I bought these from other stores in person and didn't have any problem. It must be from shipping and handling.
