Sturdy
Color: No Stuffing Blue Eel
It’s has held up pretty good for my aggressive chewer dog. She typically tore these types of toys apart immediately. One of the ears she pulled off right away but the toy itself has stayed intakes (so far). It keeps her occupied long enough and she drags it everywhere with her.

size is small
Color: No Stuffing Blue Eel
Smaller than I anticipated but my dog enjoys it. After 3 days it is already getting ripped a little bit where the treats get hidden so not sure how long it will last. My dog is about 40 lbs.

5 Star Product vs. Destroyer of All Toys for Dogs
Style: Squirrel
Hey, just wanted to check in and let you know we got the product, it's exactly as it was described. Any other dog would have had this toy for years. Our dog bit the leg off and found both squeakers free of the toy within 10 minutes of having it unsupervised.
He really is a good boy, and you make a really good product. He just has this super power to demolish ANY toy that's made for an "aggressive chewer". It was worth the shot!

Almost Indestructable.
Style: Squirrel
We have an aggressive chewer that has yet to be able to crack this one open. It's so indestructible that ours gives up on it and only plays with it infrequently. So the minus 1 star is more about the dogs preference, maybe. But make no mistake, this is made better than any other toy I have ever seen.
