Gunnar has a few toys that are probably of equal fun for him. Outside, he has a basketball and football, and a big kong that we play with. Also some batting cage baseballs (hard rubber balls). And the much loved Flying Squirrel frisbee. Inside, a couple rope toys and tennis balls usually fill the bill for fun.
Bruzer has 1 toy he loves, a stuffed frog that he's had for a couple years. He'll run in from outside and grab it and shake it around, and he'll even fetch it a couple times. He also enjoys grabbing the other end of Gunnar's rope and playing tugowar with him.
Midnite has NO toy drive at all. Her only fun thing with toys is if you throw one to her, she'll lay on it and won't let the others have it. She enjoys marrow bones, but that's not really a toy.
