We got a lab mix (we think with a Great Dane) on Labor Day weekend 2025. She has destroyed 100% of the toys we got her that weekend, with the exception of this duck. Yes, it is missing it's feet at this point (they got chewed off and torn sometime around Halloween), but the duck itself is still intact. She chews on the duck every day, it's one of her favorite toys, and it's seen some things. We've washed it a few times in the laundry machine, and it looks nice a clean every time we pull it out and let it dry. She's gnawed on it through losing puppy teeth and getting adult teeth, and she's is currently chewing away on her duck on her bed in the living room. I understand others have reported really mixed reviews, but I'm so glad we got this duck and it's one of the only toys we've bought that I feel like was worth the price because it didn't get destroyed immediately. We plan on buying another one for Christmas.

My Dog Hates It, Yours Might Like It

Color: Blue goose - pineapple plush

Material is nice, squeaker is not that great. My dog hates this toy and refuses to interact with it I've tried multiple times to get him to play with it and he'll immediately stop playing if I touch this toy and try to get him to play with it.

Not worth the purchase

Color: Blue goose - pineapple plush

Not for aggressive chewers, my GWP destroyed this in 30 mins. The fins are completely gone and he’s already disinterested. There are better options out there.

He loved the toy

Color: Blue goose - pineapple plush, Color: Blue goose - pineapple plush

My dog loved this toy, however it is not indestructible, he had it in 2 pieces within a day, but I do need to say he is a big boy and we haven’t found a toy yet that he can’t destroy
