My dog loves it!
My golden loved this chew toy, he’s fixated on it and actually returns to it. It seems tasty and safe. Will definitely buy again and recommend it to others.

Durable & fun for aggressive chewers.
Color: Yellow
Holding up very well for our aggressive chewer. Squeaker is still intact & our 70-pound pittie breed often chooses this toy to play with over others. Pittie approved.

Not at all indestructible
It was well loved while it lasted. But this fish was delivered on Saturday and I’m writing my review on Tuesday morning. So we are looking at roughly 3 days of play. I bought the fish toy and almost immediately the fins were ripped off. But I figured as long as the body stayed intact we’d be good. But it wasn’t long before the body was ripped open as well. Very disappointed. Evidently my dog’s bite is more damaging than a bullet? I’m sure it will last all in all a week before there’s no saving it anymore. Will look for other better toys for my super chewer.

Lasted the longest of any toy we bought yet!
Very happy with the toys we bought so far! The owl didn’t last as long as the raccoon. The raccoon lost his ear pretty quickly, but the rest of the toy has held up for almost a month now. That is *significantly* longer than any other stuffed animal toy we’ve tried so far. Pretty much any other stuffed animal toy we’ve tried from Kong or elsewhere has fallen apart in a few days. This is a good toy for sharp puppy teeth! Also such cute designs. Just bought the Mallard, excited to see how it goes!

Not Pitty Proof..
Color: Bear, Color: Bear
The toy itself was very detailed and cute, But my potty had the toy about 10 mins and she took the leg off .. it’s a bit pricey. Since it didn’t last long so .. if you have pitty save your money and don’t buy it ..
