Hypoglycemia in Chihuahuas
What it is, why it happens and how to prevent and treat it
(Low Blood Sugar)
This is a central nervous system disorder caused by low sugar.
It occurs mainly in Toy breeds between six and twelve weeks of age. Often it is precipitated by stress.
The first signs
are those of listlessness and depression. They are followed by muscular weakness, tremors (especially in the facial muscles) and later convulsions, coma and death. The entire sequence is not always
seen. The dog may appear to be depressed or may be weak, wobbly and jerky; or the puppy may be found in a coma.
can occur without warning when a puppy is placed in a new home, or while being shipped. It might appear after a puppy misses
a meal, chills, becomes exhausted from too much playing or has a digestive upset. These upsets place an added strain on the
energy reserves of the liver and bring on symptoms (if the dog is susceptible).
Puppies that are weaned on rice and
hamburger are more likely to develop hypoglycemia. Their diet is deficient in certain ingredients needed to sustain the liver.
A similar condition occurs in adult hunting dogs when hunting. Care should be taken to feed these dogs before hunting
and increase the protein in their diet.
Treatment is directed at restoring blood levels of glucose. Begin at once.
Prolonged or repeated attacks can cause permanent damage to the brain. If a puppy is awake, give Karo syrup, honey or sugar
in water by mouth. You should begin to see improvement in thirty minutes. When unconscious, a puppy will have to be given
a dextrose solution intravenously. It may be necessary to treat for swelling of the brain. A veterinarian should be called
Prevent recurrent attacks by feeding a high-quality kibble diet and add to it sugar, syrup or honey. See that
the puppy eats at least every eight hours and receives a daily vitamin.
Breeders should wean puppies on a balanced
diet. Food supplements should not exceed 10 percent of the total ration. Owners of Toy puppies should not overtire them or
allow them to chill.
A condition exists in which hypoglycemia is persistent of periodic. It is caused by an enzyme
deficiency and is not responsive to treatment.

AKC breed standard:
A graceful, alert, swift-moving compact little dog with saucy expression, and with
terrier-like qualities of temperament.
Size, Proportion, Substance
Weight – A well balanced little dog not
to exceed 6 pounds. Proportion – The body is off-square; hence, slightly longer when measured
from point of shoulder to point of buttocks, than height at the withers. Somewhat shorter bodies are preferred in males. Disqualification
– Any dog over 6 pounds in weight.
A well rounded "apple dome" skull, with or without molera. Expression
– Saucy. Eyes - Full, round, but not protruding, balanced, set well apart-luminous dark or
luminous ruby. Light eyes in blond or white-colored dogs permissible. Blue eyes or a difference in the color of the iris in
the two eyes, or two different colors within one iris should be considered a serious fault. Ears
– Large, erect type ears, held more upright when alert, but flaring to the sides at a 45 degree angle when in repose,
giving breadth between the ears. Stop – Well defined. When viewed in profile, it forms a near
90 degree angle where muzzle joins skull. Muzzle – Moderately short, slightly pointed. Cheeks
and jaws lean. Nose – Self-colored in blond types, or black. In moles, blues, and chocolates,
they are self-colored. In blond types, pink noses permissible. Bite – Level or scissors. Overshot
or undershot, or any distortion of the bite or jaw, should be penalized as a serious fault. A missing tooth or two is permissible.
Disqualifications – Broken down or cropped ears.
Neck, Topline, Body
Neck – Slightly arched, gracefully sloping into
lean shoulders. Topline – Level. Body – Ribs rounded and well
sprung (but not too much "barrel-shaped"). Tail – Moderately long, carried sickle either up
or out, or in a loop over the back with tip just touching the back.
(Never tucked between legs.) Disqualifications
– Docked tail, bobtail.
Shoulders – Lean, sloping into a slightly broadening support
above straight forelegs that set well under, giving free movement at the elbows. Shoulders should be well up, giving balance
and soundness, sloping into a level back (never down or low). This gives a well developed chest and strength of forequarters.
Feet – A small, dainty foot with toes well split up but not spread, pads cushioned. (Neither
the hare nor the cat foot.) Dewclaws may be removed. Pasterns – Strong.
Muscular, with hocks well apart, neither out nor in, well let down, firm and sturdy. Angulation
– Should equal that of forequarters. The feet are as in front. Dewclaws may be removed.
In the Smooth Coats, the coat should be of soft texture, close and glossy.
(Heavier coats with undercoats permissible.) Coat placed well over body with ruff on neck preferred, and more scanty on head
and ears. Hair on tail preferred furry. In Long Coats, the coat should be of a soft texture, either
flat or slightly wavy, with undercoat preferred. Ears – Fringed. Tail
– Full and long (as a plume). Feathering on feet and legs, pants on hind legs and large ruff on the neck desired and
preferred. (The Chihuahua should be groomed only to create a neat appearance.) Disqualification
– In Long Coats, too thin coat that resembles bareness.
Any color - Solid, marked or splashed.
The Chihuahua should move swiftly with a firm, sturdy action, with good reach in front equal to
the drive from the rear. From the rear, the hocks remain parallel to each other, and the foot fall of the rear legs follows
directly behind that of the forelegs. The legs, both front and rear, will tend to converge slightly toward a central line
of gravity as speed increases. The side view shows good, strong drive in the rear and plenty of reach in the front, with head
carried high. The topline should remain firm and the backline level as the dog moves.
Alert, projecting the ‘terrier-like’ attitudes of self importance, confidence,
Any dog over 6 pounds in weight.
Broken down or cropped ears.
