Terrible!!!!
Size: 15", Style: Duck
My 2 Australian shepards destroyed this cheaply made toy in 20 minutes! It's advertised for tough chewers, lol, the material it was made from is so thin, you could almost see through it. Don't waste your time or money!

My dogs love it
Size: 15", Style: Rabbit
I have to say, this is not an indestructible toy. It would have been better made without the squeaker or filling in the head. Once I removed those (after the dogs dug them out) they have played with this and the chicken (by the same company) for months. It's looking a bit ragged and I had to eventually cut the face off since they had chewed into it. However, the ropes have held despite multiple games of tug-of-war. My rat terrier and Moxie mix love these toys. Best ones we've found to last.

Quality Toy
Size: 15", Style: Duck
Fun durable toy for tough chewers. Material is durable and long lasting, however can unravel with extended chewing or pulling. A favorite of our dogs. Easy to throw and toss in a game of fetch.

My grand furbaby loves this yellow duck!
Size: 15", Style: Duck
I bought this yellow duck as a gift for my grand furbaby about 2 years ago. It turned out to be his favorite toy and it lasted for quite some time. So, I have bought several of them and when I go to stay with him in the summer, I take him a brand new yellow duck. He carries it around with him and he loves it! Favorite toy!

My 13lb dog loves these! But tears them up in no time!
Size: 15", Style: Rabbit
I’ve bought many of these, in different styles. My dog knows it as “bunny”, so if you tell him to “go get bunny”, this toy (or one of the other characters we’ve bought) comes back in his mouth. He loves to chase it, play tuggy, and whip his head back and forth with the poor thing. He turns these into threads hanging on to rope in no time. You’d think they would be super durable, but they don’t surprise him very long. I can’t rate higher than a 3 star, because I think they are made well but he’s just really tough on them and I keep buying one version or another because he loves bunny. LOL
