CHIHUAHUA CLUB OF
AMERICA Molera Statement
Historically, the Chihuahua developed in Mexico
and the United States has displayed a "soft spot" on the top of the head. In the Chihuahua this spot, or fontanel, is known
as a MOLERA; and is the same as that found in human babies. In the past, this molera was accepted as a mark of purity in the
breed, and it is still mentioned in most Chihuahua breed standards the world over.
It is important to note that while many Chihuahua
puppies are born without the molera, there are probably just as many born with one and its presence is nothing to become alarmed
As shown in the illustration below, the molera
in a Chihuahua will occur on the top of the head and may vary in shape and size when present.
Unfortunately, many lay people and
some veterinarians not familiar with the Chihuahua have tried to link the mere presence of a molera with the condition known
as hydrocephalus. This has caused many new-comers to the breed serious concern and undue worry. The truth is that a domed
head with a molera present does not predispose the Chihuahua to this condition. Along with the observations of devoted breeders
over the years, there is adequate medical evidence to support this statement.
- In "Diseases of the Brain" 1989,
Green & Braund stated that many clinically normal toy breeds may have open fontanels without associated hydrocephalus.
- Drs. Walker and Rivers, Veterinarians
at the University of Minnesota concluded that there did not appear to be any relationship between the presence or size of
a fontanel and the condition of hydrocephalus.
- Dr. Alexander de Lahunta of Cornell
University in New York, one of the top neurologists in this country, stated that it would be wrong to conclude that any opening
While it would be impossible to list all the
medical documentation here on this page, these few included here are perfectly clear; the presence of a molera does not mean
the Chihuahua has a medical problem.
The Chihuahua is a little dog!
They belong in the house, at their owner's side, receiving all the love they deserve to receive. With or without a molera,
the healthy Chihuahua that is loved and given proper veterinary care will live well into its teens as an irresistible member
of the family.
Tea Cup Statement
The Chihuahua Is A Chihuahua
The Official AKC Breed Standard describes the Chihuahua as a small dog that comes in two
varieties or coat types. The difference in coat type (the Long Coat and the Smooth Coat) is the only official description
used to identify a difference within this breed. Our standard does not categorize the Chihuahua by size.
For the purpose of showing and record keeping, the American Kennel
club includes the Chihuahua (along with 19 other breeds) in the Toy Group. Therefore, irrespective of their weight or physical
stature ALL Chihuahuas registered with the AKC are considered to be a toy breed of dog.
As with all living things, there will be size variance between
individual dogs within this breed. Look within the human family - brothers and sisters will differ in height and in weight,
as well as other physical attributes. They are described as humans, male or female, and there is seldom if ever a need to
break the description down further. The same holds true in regard to the Chihuahua; they are Chihuahuas - Long Coat / Smooth
Unfortunately, the additional adjectives used to describe the
size differences and physical appearances are many and have been misused for so long they now seem legitimate. Teacup,
Pocket Size, Tiny Toy, Miniature or Standard - are just a few of the many tags and labels that have been attached to this
breed over the years. The Chihuahua Club of America is concerned that these terms may be used to entice prospective buyers
into thinking that puppies described in this way are of greater monetary value. They are not and the use
of these terms is incorrect and misleading.
Occasionally, within a litter, there may be a puppy that is unusually
small. That puppy is a small Chihuahua and any other breakdown in description is not correct. To attach any of these additional
labels to a particular puppy is to misrepresent that Chihuahua as something that is rare or exceptional and causes a great
deal of confusion among those new fanciers who are looking for a Chihuahua.
The Chihuahua Club of America does not endorse nor condone the
use of any of these terms and would caution the perspective puppy buyer not to be misled by them.
We recognize that many Chihuahua fanciers do want the very small
puppy. While they are adorable and can be perfectly healthy, the buyer should be cautioned as to the extra care that
may be required with regard to their general health and well-being.
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
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.
Hypoglycemia 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
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 at once.
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.
