It's said that the best things in life are free, but that expression doesn't necessarily apply to your pet. Teaching your pet that "nothing in life is free" is actually a good way to make him more comfortable and secure in your family.

Being social animals, dogs function with a "pack mentality." They instinctively desire a clear hierarchy to keep order and reduce chaos. By assuming the role of the leader, you instill security in your pet, as well as motivate him to please you and thereby maintain his status. Practicing a "no free lunch" philosophy gently reinforces the hierarchy.

Earn and learn
Anyone - dog or human - who gets what he or she wants, whenever they want it, can become spoiled and ill behaved. The "Nothing in Life is Free" method requires your dog to "work" for everything he gets from you, including food, affection, exercise and play. While it may sound controversial at first, "you're actually just playing off of the dog's instinct to get all resources from the alpha," explains Best Friends professional trainer Shirley Moore (Sudbury, MA).

In a sense, this approach requires your dog to say "please" if he wants something. It does not require tricks, just basic manners and obeying simple commands. Teach your dog a few commands, the most important being "sit," "down" and "stay." Use only positive reinforcement methods when teaching. Once he's mastered those, make sure your dog performs one of these commands before receiving anything from you.

Challenging dogs
While not necessarily for every dog, "this method is incredibly effective on dogs that are aggressive or fearful," says Moore. "Requiring a dog to perform certain tasks before receiving anything lets him know that you are in control. Without being forceful or intimidating, you're telling him that you're the boss here, and that he has to abide by your rules. It will make him more secure in the environment, and less likely to challenge."

Dogs also become more confident when they perform tasks successfully and are immediately rewarded, adds Moore. "They really want to please you and feel great when they do."

Consistency is essential
Most domesticated dogs are born followers, and are content to assume a submissive role, but some dogs may enjoy challenging you (or your children) for a spot in the pack. This can cause growling, disobedience, overprotection of objects and even biting. It's important to always be vigilant about letting your dog know his place, and making sure the entire family practices the "No Free Rides" philosophy. "The most important rule in any dog training is consistency," stresses Moore.

In addition to being a professional trainer, Moore is the founder of Save a Dog, an all-volunteer New England rescue group (www.saveadog.com). She notes that most dogs that are surrended to shelters are turned in because of lack of obedience. Training a pet properly, and keeping him confident and secure of his place, ensures a happy home for all.
