For a game you could try a weinie-bob! Our local Humane Society has a "Doggy Fun Day" every August and we have games especially for the dogs. The weinie-bob is the most popular. Fill an ice cream bucket 1/2 full of water then pop in about 10 little bits of weinie (they float...). Set the timer for 15 sec. Whoever eats the most weinie wins!! For the prizes you could bake your own doggie bickies. There's lots of recipes on the net.
