Durable duck toy for man’s best friend
Although it was suggested that this toy would be best for small breeds, I found that it’s durable enough for my 80 pound Irish setter! It has literally become his best friend. He takes it everywhere he goes! There’s a small squeaky noise that comes from the neck area that he has to work to find. I’m sure he will eventually destroy this as he has with all his other toys, but it’s really holding up much better than anticipated.
It is well worth the $10 cost.

Really cute, well made dog toy. Was a huge hit with our pup
This toy was a big hit!
Pros
- love the heavy duty burlap-kinda fabric. Our new puppy has razor sharp teeth but this fabric is holding up really well.
- size is great for a variety of breeds
- shape is perfect for grabbing onto. Our puppy especially likes picking it up on the neck where the toy is more slender
- the extra little feet and wing flaps add some interest that have really kept her occupied
Cons
- the squeaker is in the neck where the fabric has embellishments and is a little thicker. It's a little hard to activate the squeaker but maybe the toy/stuffing needs to get broken in more and then it will be easier to squeeze that section

Awesome ball and made to last!
Color: Black & Yellow
Awesome ball! My dog loves it and plays with it all the time. He's a very aggressive chewer and there are only a few toys he can have without destroying them. Very pleased with this.

Pretty tough
Color: Black & Lake Blue
I think the toy is great, but my dog was not excited about it. He prefers the original type which is larger. I think it could possibly be cracked open by a dog with a large mouth and is intent on getting the noise maker out. But it is pretty tough.
