You’ll never have to teach a panda to walk on a leash. But if any kind of animal lives in your house, trainers at the zoo have some useful lessons.
Modern training methods rely on a simple principle of learning: If an action has a pleasurable consequence, the animal will repeat it. As animal behaviorist Emily Weiss says, "If it feels good, do it again.” So, it should be easy to mold a pet’s behavior: Reward it when it does what we like, and don’t when it doesn’t. But getting the details right can be a challenge. That’s often because we don’t understand what is rewarding to the animal. The simplest type of reward-based training involves food, and it’s incredibly powerful. It works with animals that don’t care about pleasing us or that we can’t even safely get near. Weiss has trained a Komodo dragon to enter a crate using food. But it’s critical to realize food is not all that’s rewarding and that the alternatives may be unexpected, such as when Weiss found that Aldabra tortoises could be rewarded in training by having their necks stroked. Being aware of other possible rewards can help if your pet is not particularly food-motivated, but it’s far more important than that. If you’re not aware of everything that’s rewarding to an animal, you accidentally may be training it to do exactly what you don’t want. Weiss tells of when she was trying to train chimps to hold still for injections. She was using their favorite food reward, a jiggly gelatin snack. But she couldn’t get to the first step: getting them to put their hands on the bars. The problem was they wouldn’t stop using their hands for throwing feces at her. "After a month, it finally dawned on me. What do you do when a chimp throws poop? You jump. You wipe it off,” she said. Once Weiss realized that watching her reaction was more rewarding to many of the chimps than getting a treat, the solution was simple. When humans stopped responding in an interesting way, the behavior stopped.

Training Tip: Trainers capture animals’ desired behavior
A wild animal can’t be physically manipulated like a pet can. If a lion won’t sit, it’s a bad idea to try to push its back legs underneath it to give it the idea. These limitations force trainers to use their imagination, and the resulting methods can be useful to pet trainers, as well. One useful technique is to take a natural action and put a command to it. Laurie Thompson, biologist of primates and pandas at the National Zoo, says this method is used to train the pandas in many behaviors, such as opening their mouths so their teeth can be examined and extending their front legs for blood draws. Rather than trying to force or elicit these movements, keepers simply "capture” the natural behavior by rewarding the panda when it opens its mouth on its own, and associate a word to the action. If you’re a dog owner, try this method to potty train your pup on command — a useful skill when you’re late for work or it’s raining. Choose a command, preferably a phrase you won’t accidentally use in the living room, and repeat it every time the dog goes to the bathroom. A food treat isn’t needed (and may distract); the comfort of an empty bladder is its own reward. It may take weeks of repetition, but eventually, the dog will look for a place to go when you say your command. THE ASSOCIATED PRESS
