A routine by Gerry Luff. This is the routine and cards only. You will need a dog puppet and 260 balloons. 

You are provided with five cards (all depicting types of food) and a blindfold. The five colored cards - a banana, an egg, an apple, a carrot and a bone, are freely shown to the children who have to decide which food they think the dog likes best. The dog is now blindfolded (and you can imagine what difficulty you have in fitting it!), and, one by one, the mixed-up cards are placed into the dog's mouth. Of course, he finds the bone, and then you have trouble getting the card away from him!
