Bought these for my dog and they were an instant hit. The carrot shape is cute, but more importantly they kept my dog entertained for quite a while. The squeaker still works and the toy has held up better than I expected considering how rough my dog can be with toys. I always expect squeaky toys to be destroyed within a day or two, but these have lasted surprisingly well. They're lightweight, easy for my dog to carry around, and have become one of the toys that gets picked out of the basket the most. If your dog enjoys squeaky toys, these are definitely worth a try.

Good one.

Color: carrot orange

Our Lab loved it. Nice and sturdy apart from the leaves, which were short lived. Overall a good toy for a big boy.
