Health Conditions in French
Bulldogs - Part One : Part
Two
French Bulldogs are most definitely adorable. Their
flat little faces, stubby bodies, bat ears and short backs all combine
to make for an adorable package, yet they also combine to produce
conditions which make French Bulldogs prone to some rather alarming
health conditions.
First things first -- this is a LOT of reading, and
can, at times, be rather alarming. The chances that your dog, or
your potential dog, might be afflicted with any of these conditions
drops rapidly with the amount of testing and screening your breeder
does. Even the most conscientious breeder, using only the most thoroughly
screened dogs, can still occasionally produce afflicted dogs. This
is a fact which anyone considering the purchase of a Frenchie needs
to be aware of.

The Breathing
System of the French Bulldog
Frenchies are a Brachycephalic breed - a fancy word
which basically means dogs (and cats, in the case of Persians and
some other breeds) with short muzzles, flat faces and condensed
breathing systems.
This is what's responsible for the adorable snorting
and snuffling sounds your Frenchie makes - but it's also a serious
matter for your dog's health. They also combine to make anesthetic
a serious matter for the breed. Anesthetic should only ever be administered
for the most critical of procedures - no 'putting under' for simple
nail clippings, please. Isoflourine is the most popular type of
anesthesia, for various reasons, but this is a topic best discussed
with your Veterinarian.

Heat Stroke
The shorter breathing system of the French Bulldog
is also what puts them at such very strong risk for heat
stroke. Shorter airway=less possibility of cooling the air which
the dogs draws into its body. Never, EVER underestimate your dog's
susceptibility to heat stroke. Limit their exposure to temperatures
which you might personally find only mildly hot, be conscious of
your dog's proximity to hot pavement, NEVER leave your Frenchie
in a locked car in even warm weather, and always allow them lots
of access to fresh water, shade, and cool areas to escape from heat.
Be alert, and be prepared with the things you need to save your
dog's life.

Elongated Soft Palate
One of the the most common forms of airway obstruction
in Brachycephalic breeds is due to an elongated soft palate. The
soft palate is an extension of the hard palate which forms the roof
of the mouth. The purpose of the soft palate is to serve as a mobile
flap preventing food and water from entering the nasal passages
during swallowing. A soft palate that is elongated will either hang
in front of the airway or will fall into the larynx during inhalation.
Dogs affected by chronic airway obstruction (CAO) tend to breathe
rather noisily when excited. Mouth breathing, snoring and snorting
are characteristics of this condition. These characteristics become
even more pronounced when the dog is hot or during periods of exercise.
The dogs frequently gag in an attempt to clear their airway and
occasionally bring up foam and saliva while eating or drinking.
The harder the dog breathes, the greater the swelling and elongation
of the soft palate. Most often an elongated soft palate is difficult
to positively confirm other than while the dog is under general
anesthesia, surgical correction is usually done at the same time.

Stenotic Nares
Stenotic Nares (constricted nostrils) occurs exclusively
in brachycephalic dogs. This birth defect can not be overemphasized.
The cartilages that help to shape the nostrils are too soft. As
the pup breathes in the nostril collapses restricting or shutting
off the air flow. In severe cases the pup's chest becomes flattened.
There is a nasal discharge that can either appear as watery or foamy.
Breathing is labored and accompanied by snorting. When excited or
active they tend to breathe through their mouths. This excess laboring
in order to bring oxygen to the lungs puts additional stress on
their systems, and with reduced air flow they tend not to thrive.
These dog should be treated surgically as soon as possible. Treatment
normally consists of removing a portion of the nasal cartilage to
enlarge the nostril openings.

Tracheal collapse
Tracheal collapse is the name given to a syndrome
in which the rigid structure of the trachea becomes weakened. This
weakened area collapses due to external and/or internal pressure
created during activity, thus interfering with normal respiration.
The weakened area becomes irritated. Since coughing and respiratory
exertion can cause further irritation, clinical signs will worsen
and the condition can become self perpetuating. Tracheal collapse
may occur alone or in association with another airway disorder (most
often chronic bronchitis).
A chronic "honking" cough can be an indication of this
condition. In some cases the cough can become so severe that the
animal behaves as though there is something caught in its throat.
Other indications of this disorder include; breathing difficulty,
tiring easily and exercise intolerance.
Mild cases often respond well to cough suppressants and stress reduction
(reduce intense exercise and excitement). These dogs can live long
and healthy lives. In more advanced cases surgical correction may
be necessary. In cases of combination airway disorders, treatment
of the contributing disorders may be necessary before treating the
tracheal collapse.

Cleft Palate
The palate (roof of the mouth) is a wall, partitioning
the nasal and oral cavities. This partition is made up of two parts
: the hard palate and the soft palate. The hard palate forms the
front portion of this partition and is made up of two bony plates
(one on each side) that are normally fused together at their midline
juncture. This fusion normally takes place during fetal development.
The soft palate forms the rear portion of the palate wall. Both
palates are covered with a mucous membrane.
The most common type of cleft palate results when the two bony palate
plates fail to fuse. The lack of bone fusion leaves a hole or slit
in the roof of the mouth. The cleft (hole) drastically impacts nursing
; suction is affected, a portion of the food that the puppy is able
to draw is passed into the nasal cavity, the nasal cavity is highly
prone to infection, and the puppy will literally wear itself out
trying to satisfy it's appetite. The cleft is present at birth and
can usually be detected by examining the roof of the mouth. Occasionally
milk can be observed running from a puppy's nose while it is nursing.
The only treatment for a cleft palate is to surgically close the
opening. In cases of severe clefts the affected pup is usually euthanised.
Most cleft palates are assumed to be genetic unless other causative
factors are found.

Megaesophagus
Megaesophagus is a condition in which the esophagus
is enlarged or dilated. The results of this condition are : regurgitation,
loss of overall condition and frequently leads to aspiration pneumonia.
Megaesophagus interferes with effective peristalsis thereby preventing
food from passing down into the stomach. In practical fact, it is
a really unpleasant condition for even the most tolerant of pet
owners to put up with. The dog frequently vomits almost immediately
after eating, exercising, or doing anything more strenuous than
getting off the couch. After having purchased and lived with one
dog with this condition, I wouldn't wish it on my worst enemy, let
alone their dog.
Megaesophagus can be congenital or acquired. Some of the causes
of acquired megaesophagus are : esophageal foreign bodies, esophageal
tumors, strictures, neurological disorders, autoimmune diseases
and heavy metal poisoning. Treatment for acquired megaesophagus
disorders are dependent upon the causative factors.
In the case of congenital megaesophagus in puppies,
the symptoms generally manifest shortly after the puppies begin
to eat solid foods. Affected pups will frequently begin to eat eagerly,
then suddenly back away from the food dish, regurgitate a small
amount of food, which they will eat again. By repeatedly eating
the food, the meal is liquefied, thereby making it possible to be
passed into the stomach. Portions of the food can be aspirated into
the lungs, making the puppy prone to aspiration pneumonia.
Treatment for congenital megaesophagus in puppies is primarily directed
toward maintaining and improving the nutritional status of the pup.
Food and water are usually given by raising the bowls up off of
the floor (raising the bowls helps facilitate swallowing). Many
owners have reported that feeding the pups a semi liquid or gruel
mixture has shown good results. Other pups seem to respond best
to being fed solids. Treatment has to be based upon which method
the individual pup will respond to best. The first few weeks are
the most critical. Pups that survive this critical time appear to
spontaneously improve. Any dog with congenital megaesophagus should
be spay or neutered regardless of how well it "outgrows"
its conditions.

Summation
Our personal opinion is that dogs which have received
surgery or treatment for elongated soft palate, cleft palate, stenotic
nares, ME or tracheal collapse should not be bred from, no matter
how many other redeeming qualities they may have as examples of
the breed. There are no 'screening' tests for healthy breathing
in French Bulldogs, other than the common sense and responsible
attitude of the breeder. The amount of suffering and unpleasantness
which these conditions can cause cannot be over emphasized. In the
scope of French Bulldog health conditions, while all are serious,
this is the one which causes the most alarm in me personally. Breathing
impairments are one of the number one causes of death (including
death by intentional Euthanasia) in French Bulldogs.
Finally, that cute little button nose on your Frenchie
needs loving care from time to time, even if their breathing is
perfect. The skin can dry out and crack, and scales of dry scabby
looking tissue can develop on it. The simple application of a Vitamin
E capsule split open and liberally applied will keep your dog's
nose looking healthy, shiny and kissable.
