My 10 month old Basset puppy Derfy LOVES to play with her favourite toy: a rubber chew toy in the shape of a chunk of meat (with a fake rubber bone through the middle!). She'll fetch it, play tug with it, playfight the other dogs for it, and drop it next to me as a little "gift" when she's done. Awww...
Whenever I get it our of her little toy box she gets all excited, and starts spinning and getting all excited. Sometimes I'll even use it during training.
