Puppyhood and Beyond Puppies are growing animals. When they are young, they learn much and what
is learned has a lasting impact. Even sexual patterns, which emerge as puppies mature, can be affected by early experience.
All dogs, regardless of breed, pass through various stages as they grow and develop, physically, mentally, and psychologically.
Psychologists use the term critical period to describe a specific time in a dog's life when certain experiences have a lasting
effect upon their psychological development. Understanding these critical periods and a dog's stages of development will better
help you to understand your dog's behavior and how to handle him during these special times. Additionally, puppies benefit
greatly when their owners understand their development.
Puppy Toddlers (3 - 6 Weeks) During the Toddler period, puppies emerge on their own from the litter. They
venture into the surrounding environment. This emergence from the litter is a gradual and continual learning experience. During
this stage of development puppies learn basic behavioral patterns specific to dogs. While playing, they practice different
body postures, learning what the postures mean and how they affect their mother and litter mates. They learn what it is like
to bite and be bitten, what barking and other vocalizations mean and how to make and use them to establish social relationships
with other dogs. Such learning and activity tempers their own biting and vocalizing. From the age of five weeks, the mother
teaches her puppies basic manners. They learn to be submissive to her leadership and what behaviors are acceptable. If necessary,
she growls, snarls, or snaps at them as a form of discipline. When weaning the litter, for instance, the mother will discipline
her puppies so that they will leave her alone. Because the mother disciplines them in a way that they clearly understand,
after a few repetitions, the puppies will respond to a mere glare from her. If a pup has not learned to accept leadership
(and discipline) in its early interactions with dogs, its training will be more difficult. Puppies that are removed from the
nest too early tend to be nervous, more prone to barking and biting, and less responsive to discipline. Often they are aggressive
with other dogs. Generally speaking, a puppy taken away from it's mother and litter mates before seven weeks of age, may not
realize its full potential as a dog and companion. To maximize the mental and psychological development of puppies, they must
remain in the nest with their mother and litter mates until seven weeks of age.
Socialization Period (7 - 12 Weeks) It is at this age that rapid learning occurs. At seven weeks, puppies
can learn and what they learn will have a lasting impact. Everything he comes in contact with will make a lasting impression
upon him as it never will again. Not only will he learn, but, he will learn whether he is taught or not. Though he has a short
attention span, what things he learns are learned permanently and resistant to change. Therefore, owners need to be careful
about what their puppies are learning at this time. Your puppy is very anxious to learn how you want him to behave and react,
and he needs to be shown what is expected of him in his new role as your pet. There are rules you will expect your puppy to
obey. Establish those rules NOW while behaviors are easy to establish. For instance, how your pet interacts with you is determined
during puppyhood. What he does now is what he will likely do later. So, don't allow your puppy to do things which will be
unacceptable when he becomes a dog. During this time, you and your puppy will also begin to know and understand each other.
You will get to know about your puppy's particular temperament and personality - whether he is strong-willed or eager to please,
gentle or rambunctious, shy or outgoing, and just what else makes him the endearing individual that he is. For the puppy,
this is both an exciting and somewhat confusing time. There is a whole new world of things to learn about and all sorts of
new experiences to digest. Remember that the environments you put your puppy in are more complex than those he would encounter
naturally. Puppies must now learn a new set of rules. He needs to know learn how to interact with humans and other animals
who live with them. Puppies must adapt to the patterns and tenor of their new homes. All of these experiences and the behaviors
which accompany them, must be learned. Because you will impose such important demands on your puppy, you must help him to
make the transition into the human environment. You need to lay a groundwork for a trusting, happy mutually satisfying relationship.
Keep in mind that puppies are less likely to broaden their experiences if they are insecure. In natural environments, puppies
approach new things cautiously. By giving your puppy brief, repeated experiences in new situations, you give him a chance
to become familiar. If you don't expose your puppy to a variety of situations and new environments, inappropriate ways to
adapt may be learned. During the Socialization period, there is a fear imprint period from 8 - 11 weeks. During this time,
any traumatic, painful or frightening experiences will have a more lasting impact on your pup than they would if they occurred
at any other time. An unpleasant trip to the veterinarian, for instance, at this time could forever make your dog apprehensive
about vets. To avoid this, take some treats and a toy with you. While you wait, play with your puppy and offer him treats.
Have your vet give your puppy treats along with lots of praise and petting before and after the examination. Avoid elective
surgeries, such as ear-cropping and hernia repair during this time. In general, avoid stressful situations. Remember, dogs
are social animals. To become acceptable companions, they need to interact with you, your family, and other people and dogs
during the Socialization Period. Dogs that are denied socialization during this critical period often become unpredictable
because they are fearful or aggressive. It is during this time, that your dog needs to have positive experiences with people
and dogs. Therefore, you need to socialize and teach your puppy how to interact with people and other dogs in a positive,
non-punitive manner. You should gradually introduce your puppy to new things, environments, and people. But, care must be
taken in socializing your puppy with other dogs or in areas where many "unknown" dogs frequent, prior to the time that your
dog has had three of its booster vaccinations against contagious diseases. Shopping centers, parks, and playgrounds are good
places to expose him. Begin by taking your puppy when there are few distracters. Give him time to get used to new places.
Make sure he is secure. If you have children that visit only occasionally, have your puppy meet children as often as you can.
If you live alone, make an effort to have friends visit you, especially members of the opposite sex so that your dog will
become accustomed to them. If you plan on taking your dog to dog shows or using your dog in a breeding program, get him around
other dogs. If you plan to travel with your dog, get him accustomed to riding in the car. Take him for brief rides, at first.
Go someplace fun. Remember, if new experiences are overwhelming or negative, the results could be traumatic.
Seniority Classification Period (12-16 Weeks) It is during this critical period that your dog will begin
to test you to see who the pack leader is going to be. He'll begin to bite you, in play or as a real challenge to your authority.
Such behavior is natural in the pack and not necessarily undesirable. What is undesirable is an inappropriate response on
your part. It is important, at this stage, that you establish your position as pack leader, and not just another sibling.
Other behaviors, such as grabbing at the leash, will be observed, and all are attempts to dominate you. Biting , in particular
though, should always be discouraged. Therefore, you should not wrestle or play tug of war. Such play is aggressive-inducing.
What you see as a fun game may be perceived by your dog as a situation in which he has been allowed to dominate. Wrestling,
of course, communicates to your puppy that he is allowed to bite you. Tug of war sets you up in a dominance confrontation
over an object. He learns that he can keep objects away from you. During tug of war games, puppies will often growl. Growling
is a dominance vocalization, designed to warn another pack member that they better not confront the growler or he will bite.
Puppies see these games as situations in which they have been allowed to dominate. They do not understand that these are games
designed by humans to entertain them. You can continue to play with your dog during this period, but, the relationship between
you during the play must change. No mouthing of your body should be allowed and when your dog does mouthe, you should respond
with a quick and sharp "NO!" or "No Bite!" Play that does not get rough is best. If you cannot keep the dog from getting overly
excited during a game and he persists in biting at you, don't play that way. This will only stimulate additional dominant
behavior in the future. For these reasons, this is the stage when serious training should begin. Training establishes your
pack leadership in a manner that your puppy will understand. By training your puppy, you will learn how to get him to respond
to commands designed to show that you are in charge.
Flight Instinct Period (4 - 8 Months) This is the age when puppies become more independent of their owners
and are likely to venture off on their own. Puppies that have always come when called or stayed close to their owners will
now ignore them, often running in the opposite direction. This period can last from several weeks to months. How you handle
your puppy's refusal to come or stay with you will determine whether or not he will be trustworthy off leash. It is important
to emphasize here that no puppy this young should ever be off leash except in a confinement area. Therefore, keep your puppy
on leash when this period arises and keep him on leash until he readily returns to you or shows no inclination to leave you.
The privilege of being off leash outside of a confined area, is reserved for dogs whose owners have trained them to the point
where there is no potential for them to run and fail to obey to stop or come on command. Releasing an unleashed dog in an
unconfined area that is not well trained off leash is irresponsible ownership and dangerous to your dog. Even well trained
dogs can make mistakes or become distracted by something in the environment so that they do not respond to their owners' commands.
So, how do you respond when your puppy suddenly develops the urge to bolt? First, you must, for his safety, put a leash or
a long line on your dog whenever you are not in a confined area. Second, work hard on training your puppy to come on command.
Use the recall game and the spontaneous recall. When walking your dog, suddenly run backwards and encourage your puppy to
come. If your dog still continues to bolt or run away, then your dog probably does not view you as the dominant figure in
this relationship and you require special help to resolve this problem. Even if the your puppy appears less inclined to bolt,
this does not mean that he is reliable off lead without more maturity and a lot more training.
Adolescence Period (5 - 18 months) Adolescence can appear in smaller dogs as early as five months. In larger
breeds, it can start as late as nine or ten months. In giant breeds, adolescence doesn't take place until twelve to eighteen
months. In general, the larger the dog, the longer it will take to physically mature. Some breeds can remain adolescents until
they are two and a half, or three years old. Adolescence is expressed in male dogs by scent marking behavior. Scent marking
behavior is stimulated by the release of testosterone into the dog's system. At this time, males may become macho. Male dogs
may become less friendly and even somewhat aggressive to other male dogs. He may begin lifting his leg in the house. He may
become very interested in girls, tend to roam, and certainly not interested in listening to you! Some males at this age become
totally unruly. In females, adolescence is marked by the onset of the heat cycle, estrus. During this three week period, your
bitch could become pregnant. So, keep her away from all male dogs. Bitches exhibit erratic behavior during estrus. Some get
real moody and insecure. Others become quite bold or even aggressive. Adolescence is a very difficult time for pet owners.
They are surprised when their cute little puppy becomes a free and independent thinker. Adolescence is certainly a good time
to start (or reinstitute) rigorous training. You must work hard NOW to mold the dog of your dreams.This course will teach
you training methods which are based on sound knowledge of dog behavior. You will gain knowledge about dog behavior and training
techniques. This knowledge will help you to get through your dog's adolescence. A dog that you iew as too stupid, too old
or stubborn or too spiteful can become a well mannered, enjoyable, and reliable companion. Establish yourself as the leader
of the pack. Be realistic about your expectations.You cannot expect young dogs to grow up overnight. Learn to appreciate your
dog's adolescence for it is a truly wonderful time. At this time of their lives, dogs are very energetic and exuberant in
their responses. They can be full of beans, but still, delightful playmates. You as the owner must learn to channel that energy
and exuberance into learning, working, exercising, and playing games. It is not too late to to train (or retrain) your dog
to help him to become a long-lasting companion.
Second Fear Imprint Period (6 - 14 Months) The Second Fear Imprint Period is similar to the one that occurred
during the socialization period, but, it is much less defined. It occurs as dogs enter adolescence and seems more common in
males. It is often referred to as adolescent shyness. Your dog may suddenly become reluctant to approach something new or
suddenly become afraid of something familiar. This behavior can be very frustrating to the owner and difficult to understand
because its onset is so sudden and, seemingly, unprovoked. If you notice this behavior, it is important to avoid the two extremes
in response: Don't force him to do or approach something frightening to him and don't coddle or baby him. To get through situations
that make your dog fearful, be patient, kind, and understanding. Desensitize him to the object or situation by gradually introducing
him to it and using food rewards and praise to entice him to confront the fearful object or situation. Do not coddle or reassure
him in any way that will encourage his fearful behavior. Do not correct him either. Simply make light of it and encourage
him give him food rewards as he begins to deal with his fear better. Make sure you lavishly praise his attempts! This phase
Mature Adulthood (1 - 4 Years) During this period your dog may again become aggressive and assertive. For
instance, he may become more turf-protective, by barking when someone comes to the door. Temper his protective behaviors by
teaching him how to accept strangers into your home. His friendly play with other dogs may escalate to fighting with other
dogs. Teach you dog to ignore other dogs that he sees if he can't be friendly towards them. Take him to places where there
will be a few dogs at first and train him there. Then, train him in areas with more and more dogs. Next, allow him to interact
with non threatening dogs. Puppies and bitches are good choices, if he is a male. Always praise his positive efforts to interact
or if he displays no reaction. Gradually move onto male dogs. At bit of caution here, adult members of the same sex, no matter
what animals species, tend to compete with one another. Putting together two strange adults of the same sex could result in
a fight. Watch for behavioral signs of playfulness before allowing two dogs to play together. Also, be alert to the posturing
of aggressive behaviors. Watch for circling behaviors, walking on toes, stiff tail wags, and tense facial expressions. Adulthood
is also a time that your dog may again test your position as pack leader. If he does, handle him firmly, suspend any rough
play that may be giving him the idea that he can dominate you, and continue with training. Additional classes or private help
with training may be a wise investment. It can provide you with the structure and commitment to train him that you need at
this time. Proceed with training in a matter-of-fact, no nonsense manner and your dog will become a reasonably obedient dog.
Give him lots of positive attention for his efforts!
Closing Remarks This has been a cursory look at some of the behavioral changes that often occur during puppyhood,
adolescence, and early adulthood. Other problems may arise at these stages which are not the result of the developmental period
itself, but are caused by something in the environment or the dog's basic personality. Even so, they are probably aggravated
by immaturity and you cannot afford to overlook them. Understanding, training, and perhaps professional help with training
are the keys to success. All dogs are different. Some will not exhibit the behaviors we have discussed and others will pass
through them at varying rates with smaller dogs maturing faster than large dogs. Remember that your dog needs you to play
a role in his development and you can do that with knowledge and commitment to training. Learning plays a significant role
in a dog's development. Through training, you actively take part in that process. This course has been carefully designed
with the capacities of developing dogs in mind. Throughout the course, you and your dog will be observed. You will be advised
if your dog exhibits behaviors which may be warning signs of potential problems. We will teach you exercises which will help
your dog to be a good companion. The exercises your dog or puppy will learn should not tax him. Learning can be fun and each
dog can achieve success.
