My Tundra, a husky mix, plays with stuffed animals. His favorites are the red ones! He chews out hard eyes because when he shakes them, the hard eyes hurt him! He tosses them up in the air and then shakes the daylights out of them!
Tundra also plays his own version of "Hacky-Sack". He carefully places an object on his left front paw, flips the object, and catches it in his mouth before it hits the ground. He will find a leaf, or nut, or any found object to play with like this and will busy himself for an hour or so. He does this inside or outside! He can really shake the house when he gets going!
My little rat terrier, Suzie, doesn't play! She was found in a junk yard and taken in by an older lady, so I don't know if she ever played. She does a good cuddle though!
