                                                    Hypoglycemia
    Hypoglycemia is an extremely serious central nervous system disorder caused
    by low blood sugar.  It occurs mainly in Toy breeds between the age of six and
    twelve weeks, and precipitated by stress, such as weaning, vaccinations or
    being placed in a new home.  Hypoglycemia is not necessarily a disease, but it is
    a symptom.

    Puppies that are weaned suddenly at an early age (less than 8 weeks) will have
    a tendency to have low blood sugar.  They aren't given enough time to adjust
    to solid food, and suddenly removed from their mother without a thought as to
    how it is affecting the babies.  Usually this is done out of greed and not
    wanting to take care of the puppies any longer than necessary to get them out
    the door and someone
    else's responsibility.  A responsible breeder will take the time necessary to
    see that the puppies are on solid food long enough to avoid upsetting their
    digestive system before they let them go to a new home.  Since they can't
    tolerate a sudden change in their food, their digestive tract becomes upset,
    they do not get the full value of their food, then their blood sugar drops.

    Parasites will prevent puppies from absorbing the nutrients from their food.  
    Parasites all have different life cycles.  Worming one time and a few days of
    Albon won't do the job.  The wormer only kills what is in their stomach at the
    time.  Albon is an antibiotic that only tides them over an outbreak of coccidia
    and counteracts a secondary infection coccidia causes, and does nothing to kill
    the parasites.  The only alternative to that is a program of PREVENTION.

    Hypoglycemia in an otherwise healthy puppy can be prevented by owners who
    permit the puppies to be handled by everyone they come in contact with.  
    Puppies become body sore, just like human babies do.  Then they get tired,
    just want to sleep, then when, or IF, they wake up, their blood sugar has
    dropped. Common sense tells us that a human baby can't tolerate a lot of
    activity, handling, and constant playing.  Neither can a puppy.  Traveling
    sometimes causes car sickness, until he has had a period of time to slowly
    adjust to traveling, be prepared to give Nutri-Cal about every two hours while
    traveling.

    Most neonatal puppies have very little subcutaneous fat.  Energy is supplied
    through frequent feedings, and reserve energy is supplied by glycogen in the
    liver.  The liver is the last organ to grow in size, usually mature about 12
    weeks, while the brain consumes the most energy.  Puppies in the six to twelve
    week age group have a liver too small to produce the glycogen needed to fuel
    the brain without frequent feedings..  ANY TIME A PUPPY IS NOT FED
    FREQUENTLY, BECOMES TIRED, GETS TOO COLD, HAS A DIGESTIVE
    UPSET, OR HAS A PARASITE OVERLOAD, HE IS HEADED FOR TROUBLE,
    IN THE FORM OF HYPOGLYCEMIA.

    The first signs of hypoglycemia are listlessness and/or depression.  The next
    signs are muscular weakness and tremors, especially in the facial muscles,
    sometimes in the back muscles, which causes the head to be pulled back or to
    the left, sometimes crying pitifully.  Convulsions and / or seizures follow, then
    coma and death.  The entire sequence is not always seen in all hypoglycemic
    puppies.  The puppy may
    seem weak, or uncoordinated, unable to stand or walk, with the appearance of
    being drugged, or wobbly and jerking, or he may be found in a coma and totally
    unresponsive.

    Hypoglycemia can occur without warning when a puppy is placed in a new home,
    or while being shipped to a new home.  Symptoms may appear if anything upsets
    his feeding and rest routine, if he plays too hard and too long, or when his diet
    is changed.  It can happen within 72 hours after he has had vaccinations.

    Treatment consists of restoring blood levels to normal as quickly as possible
    to avoid brain damage.  Intravenous dextrose, done by your vet, is the fastest
    way to restore the glucose levels.  Until you can get the puppy to your vet, give
    him Karo syrup or honey by rubbing it on his gums and under his tongue.  
    Because hypoglycemia is a symptom of something else going on with the puppy,
    the puppy will ABSOLUTELY need to be vet checked to determine what the
    existing problems are that need correcting to prevent further episodes.
