Puppy Development
    Milestones of Small Dog
    Puppy Development

    Small dogs grow and develop quickly and often reach maturity before larger breeds.  
    Puppy development follows a predicable path yet each puppy is unique and each breed
    is slightly different at the various stages of development.  The old rule of each year of a
    dog’s life is equivalent on seven years for human is not completely accurate. For most
    small dogs, the average life span is approximately 16 years.  Small dogs mature early
    and females often have their first heat by the age of 6 or 7 months.  By the age of 12 or
    13 months, they are often ready to be bred.  
    Many changes take place in the first year of life.  Puppies go from a relatively helpless
    neonate who cannot see or hear or eliminate by himself to a fully grown, agile, sexually
    mature adult all in less than 12 months.  When do all of these changes take place?

    First Two Weeks of Life:
    At birth, your puppy’s eyes and ears are closed.  In fact, only 3 senses are working—
    touch, taste, and smell and even then they are not fully developed.  They can feel and
    respond to pain, discomfort and minor disturbances by whining or crying. Their body
    temperature is well below that of a mature dog, and they are incapable of either
    urinating or defecating on their own.  Their first main mission in life is to find warmth and
    food.  They have no teeth, but their nails are fully developed and some may even need
    trimming in the first week of life.














    Their main activity at this time is to search out nourishment from their mom and sleep.  
    Newborn puppies sleep most of the time, often twitching in their sleep and move only to
    reposition their body.  Twitching occurs because at this point in their young lives, they
    sleep is the REM stage, a stage characterized by high brain activity.  Beyond that, they
    have little interaction with litter mates or the environment other than to huddle close to
    litter mates and mom for warmth.   They depend on their mother to provide the food
    they need and to help them potty.  Mother also has the assigned task to clean up after
    all pottying activity, a job that mother dogs accept happily.  

    Two Weeks:

    At around two weeks of age, the puppy’s eyes open and then several days thereafter,
    their ears open.  At first their vision is blurry but soon vision improves and the puppies
    can now see the world at least from their vantage point.  Even into adulthood dogs do
    not have particularly sharp vision.  Most puppies will have doubled their birth weight by
    about 2 weeks of age.

    Once their ears open they may begin to startle when they hear sounds.  Even from the
    very beginning, their range of hearing is nearly twice that of humans and into the
    ultrasonic range.  Puppies usually receive their first dose of worming medication at
    around 2 weeks of age and are wormed about every 2 weeks thereafter as a
    precautionary measure.

    Three Weeks:

    At three weeks of age, puppies become somewhat adventuresome and begin to mover
    around more, though they are not very sure footed at this age.  This might be
    equivalent to the crawling stage in the human infant.  But progress occurs rapidly and
    by 3 ½ weeks most puppies are getting around well on their own four paws.  Their eye
    sight and hearing are improving daily.  This is also the time that they begin to lap liquids
    and mouth solid foods if the consistency is mush-like. They also begin to have limited
    interaction with litter mates, but the majority of this interaction revolves around who is
    going to serve as pillow and who is going to serve as blanket as they pile up in one
    small corner of the whelping box.  Puppies take turns sleeping on top of the pile and
    cuddling underneath and don’t seem to mind either position.  
    Three weeks is the ideal time for socialization to begin.

    Four Weeks:

    Different textures can be added to their box and puppies can snuggle up against the
    breeder who is wearing a variety of different textured clothes.

    At four weeks he is also beginning to regulate his own temperature and feel the urge to
    pee and poop on his own.  He won’t always need Mama to stimulate him to go potty, yet
    most good moms continue to clean up after their pups at least for a while.  So potty
    training is on hold for several more weeks.

    By four weeks of age, most puppies have figured out what “real” food is and continually
    eat more dog food, nursing less.  They are far from being weaned at this age.  They are
    moving around more and sleeping less.  This is the time where socialization to the
    outside world begins.  Puppies should begin listening to music or TV, hear
    environmental sounds such as the dishwasher, hair dryer, can opener, and vacuum
    cleaner.  It is also a good time to introduce different textures into their world.  They can
    be given opportunities to walk on different surfaces such as wood, tile, concrete, grass,
    carpet and dirt.

    Five Weeks of Age

    By five weeks of age, he is considered a toddler and will become very busy interacting
    with litter mates and of course humans.  If given toys at this age, he will explore but
    rigorous play is still in this young pup’s future.  Mama will try to encourage her
    youngsters of this age to wean, making herself less available for free drinks at any time
    of the day.

    Puppies show first signs of “play fighting” with litter mattes, but it is too soon to
    determine temperaments and canine pecking orders at this time.  Some moms actually
    regurgitate food for their young, although is not seen very much in domestic dogs.  

    Six Weeks:

    At six weeks of age, puppies are ready for their first shots and they should have
    already had a couple of wormings by now.  Play takes on new dimensions and toys
    become fascinating objects.  Puppies want to explore and will find ways explore every
    inch and cranny of their allotted space.  During this period, breeders should continue to
    offer stimulation in the form of sounds, smells, and textures and provide interesting
    environments for puppies to explore.  Mama continues to teach her puppy manners
    especially “bite suppression.    Puppies learn what appropriate canine behavior is and is
    not through the use of play and observing other canine body language. These
    behaviors will be repeated for two weeks until they become fully weaned and ready to
    go to their forever home.  Smaller breeds such as Yorkshire terriers, teacup toy poodles
    and Chihuahuas may need more time with mama and the litter mates.  A puppy of 8
    weeks is curious, friendly, outgoing and fully ready to learn.  If socialized correctly he will
    be completely ready and eager to please his new human family.  


    Eight Weeks:

    At eight weeks of age, the puppy will be ready to go to their new home.  The first few
    nights will be tough for the little guy as he has not had too much experience being on
    his own.   Socialization is very important during this stage of puppy development and will
    continue to approximately 12 weeks of age.  The more new sights, sounds, and smells
    that he can experience the better. Puppies that have lots of socialization experiences
    and stimulus during this period will be much better equipped to handle change as they
    grow.  This is also a great time to begin training.  The first training is potty training and
    then simple commands.  Basic obedience is best started at home and then enrollment in
    a formal obedience class once he is fully immunized is always a good idea.  If you do
    decide to work at home, there will be a couple of things you will want to teach your dog.

           Teach Your Puppy To Walk on A Leash



    Immunizations are vital to the health of young puppies and should take priority over any
    attempts at socialization.  For example your young puppy is not ready for a dog park
    until all of is immunizations have been given.  The best rule of thumb that I have been
    able to determine is to treat a pup as if it were a newborn human infant.  Anything you
    would not do to an infant, you should not do to a puppy.  

    Twelve to Sixteen Weeks:

    This is considered to be the puppies “tween” stage because the first signs of
    independence is noticeable.  This is a very demanding stage of puppy development and
    the well-behaved little guy who stuck right by your side will suddenly want to ignore you
    and do his own thing.  Behavior is a little erratic during this period and tends to fluctuate
    from being a sweet cuddly baby to a stubborn tween.  Teething begins in earnest and
    the puppy tries to find anything and everything to chew upon, whether it is a favorite
    wooden chair or a person’s toes.

    This is the time when potty training usually occurs and beginning obedience training
    such as how to walk on a leash, not necessarily how to heel.  By the end of this period,
    the puppy should have received his third set of puppy shots and a Rabies vaccination.

    17 to 40 weeks:

    Congratulations, your fur son has reached his teen years.  Attitude is everything during
    this period.  He tries to break all the rules if given the opportunity and test the limits.  As
    long as socialization and training continue, the puppy does not grow into a juvenile
    delinquent. He can attend puppy classes and learn basic commands.  He will lose his
    baby teeth and gain a full set of adult teeth.  Dental care is important during this time.  
    He or she will reach sexual maturity some time during this age and it is a good idea to
    have him neutered and her spayed.  Most veterinarians recommend sometime by 6
    months of age.  

    41 to 52 Weeks:
    The end of this period marks the end of puppy-hood and the beginning of sexual
    maturity at least for small breeds.  Large and giant breed puppies take longer to
    mature.  Small breeds will reach their full adult size, height and weight.  Large or giant
    breeds will still be in the adolescent stage.
