This toy might just be the best toy invention, made specifically for dogs.
My puppy is so determined he doesn't quit till he gets whatever I put in the middle, whether it be peanut butter or some kind of treat.

Pros: Easy to clean, entertains for hours

Cons: N/A

It is a great toy and lasts but my dogs aren't interested in it, maybe b/c it doesn't squeak and is hard to chew.

Pros: great as far as durability

Cons: my dogs have no interest in this toy

This is a strong toy, no doubt..but it was no match for an american bulldog we were fostering. it survived for a bit, he had to work at it to get it apart, but after a few minutes of work he tore it into tiny pieces. If you have a strong chewer, opt for the Black KONG.

Pros: it's a KONG

Cons: our American Bulldog we fostered had this tore apart in no time

My dogs have spent hundreds of hours working their Kongs. My most recent dog can break the red ones but not the black. The company has them labelled properly.

Pros: Great for all but 1

Cons: My strong chewer can break it

I absolutely love these toys for dogs...you can stuff them and freeze them and they will keep them entertained forever. Dogs even love them when they are empty since they bounce around so well and are not easily chewed to pieces! This is the first toy that I look at when I go into the stores because it lasts so long, and you can put it in your dishwasher and it is easily cleaned, water runs right through.

Pros: Entertaining and indestructable!

Cons: Can be messy when stuffed.
