Invincible dog toy
Style: Squeaky Duck
This dog toy is superior to all other dog toys. I got this for my 98 lb German shepherd over a year ago. It is very durable and has a LOUD squeaker. Most toys (even Kong usually) he will chew on for a few weeks but the squeaker doesn't last very long. This duck has a secondary layer that my dog finally broke into 14 months after buying and it still squeaks!!! 10/10 would recommend

Takes a licking and keeps on…you know…
Style: Squeaky Duck
Our pit is a determined chewer, and this has lasted over a week. If he annihilates it tomorrow, it was still a great success!

Great value and cute toy!
Style: Squeaky Duck
Our dog LOVES this toy. Once he chewed through the duck the inside toy became one of his favorites.

Destructable
Style: Squeaky Duck
Destructible!!!! My 13-pound dog stripped the bird toy down in a day. I’d recommend strong or highly motivated chewers get a different toy.

Cute, original toy!
So cute and the pups loved playing with this bouquet. We also got the ring. Zippy Paws has the best quality products!
