Dog training

Dog training is the process of teaching a dog to exhibit certain desired behaviors in specific circumstances. Some examples are:

Teaching a dog basic obedience commands (part of obedience training)
Teaching a dog to perform tricks casually or for circus acts
Teaching a guide dog to lead the blind
Teaching a rescue dog to find victims of a disaster
Helping a hunting dog learn to perform its instinctive behaviors at appropriate times

The specific behaviors taught in each case are different, but the underlying principles are similar.

In the wild as pack animals, canines have natural instincts that favor training. These instincts are manifested when the dog lives with humans as a desire to please a handler, as a dog would please senior members in a pack in the wild. The handler is simply whoever is working with a dog at the time.

Basic training

Most dogs, no matter their eventual advanced training or intended purpose, live with people and therefore must behave in a way that makes them pleasant to have around and for their own safety and that of other people and pets. Dogs do not figure out basic obedience on their own; it must be trained.

Age for early training

Dog training begins virtually at birth. Dogs that are handled and petted by humans regularly during the first eight weeks of life are generally much more amenable to being trained and living in human households. Ideally, puppies should be placed in their permanent homes between about 8 and 10 weeks of age. In some places it is against the law to take puppies away from their mothers before the age of 8 weeks. Before this age, puppies are still learning tremendous amounts of socialization skills from their mother. Puppies are innately more fearful of new things during the period from 10 to 12 weeks, which makes it harder for them to adapt to a new home.

Puppies can begin learning tricks and commands as early as 8 to 12 weeks of age; the only limitations are the pup's stamina, concentration, and physical coordination. It is much easier to live with young dogs that have already learned basic commands such as sit. Waiting until the puppy is much older and larger and has already learned bad habits makes the training much more difficult.

There are some professional trainers who disagree with this idea, particularly those who train working dogs, detection dogs, police dogs, etc. They feel that obedience work shouldn't start until the dog is at least a year old, or after the prey drive has fully developed. These trainers also take the position that spaying and neutering is harmful to the training process, again because of its negative impact on the dog's prey drive.

Basic training classes

Professional "dog trainers" usually do not train the dogs, but actually train the owners how to train their own dogs. Although it is also possible to send a dog away to a training school, the owner still must at some point learn what the dog has learned and how to use it and reinforce it. Owners and dogs who attend class together have an opportunity to learn more about each other and how to work together under a trainer's guidance. Training is most effective if everyone who handles the dog takes part in the training to ensure consistent commands, methods, and enforcement.

Formal training in classes is not always available until the puppy has completed all its vaccinations at around 4 months; however, some trainers offer puppy socialization classes in which puppies can enroll immediately after being placed in their permanent homes as long as disease risk is minimal and puppies have receieved initial vaccinations. In most cases, basic training classes accept only puppies who are at least 3 to 6 months old.

Communicating with the dog

Fundamentally, dog training is about communication. From the human perspective the handler is communicating to the dog what behaviors are correct, desired, or preferred in what circumstances. From the canine perspective the handler must communicate what behaviors will give the dog the most satisfaction to his natural instincts and emotions. Without that inner satisfaction a dog will not work well.

A successful handler must also understand the communication that the dog sends to the handler. The dog can signal that he is unsure, confused, nervous, happy, excited, and so on. The emotional state of the dog is an important consideration in directing the training, as a dog that is stressed or distracted will not learn efficiently.

According to Learning Theory there are a four important messages that the handler can send the dog:

Reward or release marker: Correct behavior. You have earned a reward. For example, "Free" followed by a reward.
Bridge: Correct behavior. Continue and you will earn a reward. For example, "Good".
No reward marker: Incorrect behavior. Try something else. For example, "Uh-uh" or "Try again".
Punishment marker: Incorrect behavior. You have earned punishment. For example, "No".

Using consistent signals or words for these messages enables the dog to understand them more quickly. If the handler sometimes says "good" as a reward marker and sometimes as a bridge, it is difficult for the dog to know when he has earned a reward.

Rewards can be treats, play, praise, or anything that the dog finds rewarding. Failure to reward after the reward marker diminishes the value of the reward marker and makes training more difficult.

These four messages do not have to be communicated with words, and nonverbal signals are often used. In particular, mechanical clickers are frequently used for the reward marker. Hand signals and body language also play an important part in learning for dogs.

Dogs usually do not generalize commands easily; that is, a dog who has learned a command in a particular location and situation may not immediately recognize the command to other situations. A dog who knows how to "down" in the living room may suffer genuine confusion if asked to "down" at the park or in the car. The command will need to be retaught in each new situation. This is sometimes called "cross-contextualization," meaning the dog has to apply what's been learned to many different contexts.

Reward and punishment

Most training revolves around giving the dog consequences for his behaviour, in the hope of influencing the behaviour the dog will exhibit in the future. Operant conditioning defines four types of consequences:

Positive reinforcement adds something to the situation to increase the chance of the behaviour being exhibited again (for example, giving a dog a treat when he sits.)

Negative reinforcement removes something from the situation to increase the chance of the behaviour being exhibited again (for example, releasing the tension on an uncomfortable training collar when the dog stops pulling on the leash).

Positive punishment adds something to the situation to decrease the chance of the behaviour being exhibited again (for example, growling at a misbehaving dog).

Negative punishment removes something from the situation to decrease the chance of the behaviour being exhibited again (for example, walking away from a dog who jumps up).

Most modern trainers say that they use "positive training methods", which is a different meaning of the word "positive" from that in operant conditioning. "Positive training methods" generally means preferring the use of reward-based training to increase good behavior over that of physical punishment to decrease bad behavior. However, a good trainer understands all four methods, whether or not she can put operant-conditioning terminology to them, and applies them as appropriate for the dog, the breed, the handler, and the situation.

Rewards

Positive reinforcers can be anything that the dog finds rewarding - special food treats, the chance to play with a tug toy, social interaction with other dogs, or the owners attention. The more rewarding a dog finds a particular reinforcer, the more work he will be prepared to do in order to obtain the reinforcer.

Some trainers go through a process of teaching a puppy to strongly desire a particular toy, in order to make the toy a more powerful positive reinforcer for good behaviour. This process is called "building prey drive", and is commonly used in the training of Narcotics Detection and Police Service dogs. The goal is to produce a dog who will work independently for long periods of time.

Some trainers believe that the toy acts as a positive reinforcer for the desired behavior, when in all likelihood the prey drive works on an entirely different level from standard training and conditioning techniques. This is seen most clearly in the fact that, according to the laws of operant conditioning, positive reinforcers lose their effectiveness if they're given every single time a dog does what is desired of him; the more predictable the reinforcer, the less reliable the behavior. Yet detection dogs only work well when they are always rewarded with a toy, every single time they find drugs or explosives, etc. The reason for this disparity is that when a dog is trained through the prey drive, the training activates an instinctive, automatic sequence that has to be completed in order for the dog to feel satisfied. That sequence is: search, eye-stalk, chase, grab-bite, and kill bite. So when a dog searches and finds drugs or explosives, he feels he hasn't finished his job unless he can bite something. This is the primary reason he's always given the toy. It's not really a positive reinforcer. If it were it would reduce the reliability of the behavior overall. It's a means of completing the predatory sequence for the dog.

Punishments

"Positive punishment" is probably the consequence that is least used by modern dog trainers, as it must be used very carefully. A dog is generally only given this type of punishment if it is willfully disobeying the owner. Punishing a dog who does not understand what is being asked of him is not only unfair to the dog, but can make the dog a fearful or unwilling worker.

Punishments are administered only as appropriate for the dog's personality, age, and experience. A sharp No works for many dogs, but some dogs even show signs of fear or anxiety with harsh verbal corrections. On the other hand, certain dogs with 'harder' temperaments may ignore a verbal reprimand, and may work best if the reprimand is coupled with a physical punishment such as a quick tug on a training collar. Trainers generally advise keeping hand contact with the dog to positive interactions; if hands are used to threaten or hurt, some dogs may begin to behave defensively when stroked or handled.

Avoiding punishment

Keeping a puppy on a leash in challenging situations or in his crate or pen when not closely supervised prevents the puppy from getting into situations that might otherwise invite an owner's harsh reaction (such as chewing up a favorite pair of shoes).

The command voice

When giving commands to a dog, a calm, firm, authoritative voice is most effective. Dogs do not respond well to hesitant, pleading voices, nor to yelling, which might sound to the dog like threatening barking or scolding. It is also important that the word used for the command and the pitch of the voice be consistent each time the command is delivered so that the dog can more easily learn what the owner means (siiiiiiiiiiiit does not sound the same as sit, for example).

Using the puppy's name before a command ensures that the dog knows that a command is coming, that it is for him (rather than for other dogs, children, or people), and that he should pay attention. This is important because dogs hear a lot of human speech that has no relevance for them at all, and it is easy for them to disregard commands amongst the babble.

To reinforce the command, the dog always gets some kind of reward or reinforcement (praise and usually a treat or toy) when it performs the action correctly. This helps the dog to understand that he has done a good thing.

Note that not all dogs are trained to voice command. Many working breeds of dog are not trained to a voice command at all; they are taught to obey a combination of whistles and hand signals. Deaf dogs are perfectly capable of learning to obey visual signals alone. Many obedience classes teach hand signals for common commands in addition to voice signals; these signals can be useful in quiet situations, at a distance, and in advanced obedience competitions.

The specific command words are not important, although common words in English include sit, down, come, and stay. Short, clear words that are easily understood by other humans are generally recommended; that way, people will understand what a handler is telling his dog to do and other handlers have a good chance of controlling someone else's dog if necessary. In fact, dogs can learn commands in any language or other communications medium, including whistles, mouth sounds, hand gestures, and so forth.

Training tricks

Many dog owners teach their dogs tricks. This serves several purposes: Develops a stronger relationship between the dog and human; provides entertainment; and engages the dog's mind, which can help to alleviate problems caused by boredom. For example, the shake hands trick involves the dog raising its paw and placing it into an outstretched hand. An example of a useful trick is teaching a dog to ring a bell to go outside. This helps prevent the stress placed on an owner when trying to recognize whether the dog needs to relieve itself. For more information, see clicker training.

Teething

At anywhere from three to six months of age, a puppy begins to get its adult set of teeth. This period can be quite painful and many owners do not recognize the natural need to chew. By providing specific chew toys designed to ease the pain of teething (such as a frozen nylon bone), attention can be diverted from table legs and other furniture. Many people also use a bad-tasting, bad-smelling spray on favorite items, such as shoes, furniture, or even wallpaper, to discourage chewing. Bitter apple is a commonly used spray, but there are several commercial sprays available. Different sprays work better for different applications, owners, or puppies.

Specialized training

Dogs are also trained for specific purposes, including:

Detection dogs
Service dogs, incluidng guide dogs
Herding dogs, livestock guardian dogs, and sheep dogs
Hunting dogs
Police dogs
Rescue dogs

Guard animals

Regarding dogs, due to their natural social structure which is territorial protective of companions, even companion animals will exhibit some form of alert behaviors toward intruders. However true guard dogs and police dogs are dedicated animals in the sense that they are not simultaneously intended to be companion animals.

There are several methods regarding the training of guard animals, western (e.g. Koehler Method) and eastern, and certain breeds are typically used in this capacity. The Schutzhund method also contains a portion relating to protection, and generally means the animal will bite on command, and will not release until commanded.

Positive punishment can include electric shocks related to attempting to eat food other than in the designated food receptacle, for example so a guard dog is not tempted by food given to to it by an intruder.

Service animals

Service dogs, such as guide dogs, are carefully trained to utilize both their sensory skills and the protective instincts of dogs (as pack animals) to bond with a human and help that person to offset a disability in daily life. The use of service dogs is an every-growing field, with wide range of special adaptations.
