Id like to give 3.5 if I could and considered 4 but it only lasted a little over a month. But in that time our 7 month 40 pound mixed breed did love this 'duck'
She would carry it and toss it around and sit and squeak it. We loved it too such a cute toy. But just the other night we were remarking how this lasted and looked down to see Xena had gotten a duck foot off and was working on the other. Had to toss it then since the squeaker was exposed and she was trying to eat pieces of fabric.
But I would consider getting another one when she is a little older an hopefully a little less of a chewer
