Because you're not only training your pet to shake hands or sit up, you're developing a lifelong bond of trust and friendship with that animal. So build the bond in a positive way with respect for your pet. If you see me in The Greatest Show On Earth, you'll notice that I often use whole loaves of fresh bread as rewards for my elephants, as well as using praise. Animals are very aware, and they want to please you. When you're training any animal, whether it's a house cat or a big cat like the tigers I perform with, a puppy or an elephant, remember to be consistent.
Animals learn by repeating a behavior over and over many times in the same way.
As you care for your pet, pay close attention. See what it does when it is hungry, happy, tired, excited. Notice its behavior, and not only will you be able to take better care of your pet, you will become a better trainer. We have found, through more than 128 years of living with, working with, and caring for animals in The Greatest Show On Earth, that the best way to train an animal is to observe what it likes to do. Then showcase that natural behavior, as well as its unique personality.
