Not as pictured
From the picture, this duck looked stuffed and full. Instead it is completely flat.

Not so durable, but still decent
Durable...if you don't have a dog that chews. But it is cute and he LOVED it while it lasted. He just has a vengence against all squeakers.

Great Soft Duck Toy
I've bought several of these over the years. My Australian Shepherds love them and often play with the duck on their own. Eventually one surcomes to an occasional tug-a-war. My dogs are moderate tuggers.

It's his favorite toy
This duck is his favorite toy. He takes his "duck baby" up to bed with him every night. It's held up to his love well. This is his second duck as the one we received as a gift 2 years ago is still alive and well just very dirty and in need of a stand in when his time comes. Over all Rico is quite happy with Duck and would give 5 barks.
