Bulldogs belong
to a group of dogs know as "brachiocephalic"
breeds or "short-nosed" breeds. Since dogs do not sweat to cool themselves as
people do they rely on panting to help expel excess heat. The short nosed
breeds cooling mechanism and air transfer is much less than other breeds making
them very prone to over heating, heat exhaustion, and heat stroke.
Temperament can also play a role in over heating. The very excitable Bulldog,
or the under socialized Bulldog that gets nervous or "worked-up" is at a higher
risk for breathing problems. Through excessive panting or barking Bulldogs can
actually cause edema (swelling) to their throats and larynx causing severe
respiratory distress. Start early with your puppy to get them used to different
types of situations involving crowds, children, multiple dogs, veterinary
hospitals, dog shows, etc. so they accept these as a normal part of their
life. Many "old time" Bull dog breeders carry lemon juice to squirt in their
dog's mouth to help clear their throats. Lemon juice is actually considered a mucolytic and is excellent at clearing mucus- so this might be worth a try if
your pet has problems.
In certain individual Bulldogs breathing problems are more pronounced and this is
known as "Brachiocephalic Syndrome."
The first component of this is pinched
nostrils (stenotic nares). The
openings to the nostrils in these dogs can be no more than slits. Air sounds
can frequently be heard with each breath. If you pinch your own nostrils and
try to take a deep breath you will experience a feeling of negative pressure
down near your larynx or voice box. This negative pressure does several
things. It stretches or pulls on the soft palate which is the soft tissue just
behind the hard palate (hard roof of the mouth). This condition is known as an
elongated
soft palate.
These dogs will make excessive snorting or snoring noises. Often you can
feel strong vibrations when lightly cupping your hand over the underside of
their necks. Sometimes too, they will regularly spit up white frothy foam that
becomes trapped in their throats. Pinched nostrils and elongated soft palates
often go together and can only be helped by surgery. The nostrils can be opened
with a "wedge resection" to remove tissue and create a wider opening. This can
be done with very little scarring and the sooner it is performed on puppies the
better. The soft palate is best shortened using a C02 laser. Lasers cause less
swelling, bleeding, and pain allowing the pet to be discharged the same day.
The benefits of these surgeries can be dramatic, and are greater in younger
animals as compared to a dog that has been having problems for several years.
Two other components of the syndrome are everted
laryngeal saccules and a
hypoplastic trachea. The saccules are located
down within the openings of the trachea or windpipe. The negative pressure
formed higher in the airways causes a sac on either side to get sucked out into
the airway with every breath. These appear almost as little balloons and
further occlude the airflow. These dogs are usually the ones that have had
ongoing problems left untreated. They tend to have trouble breathing with the
least amount of activity or excitement. The saccules should be excised (cut
out) to correct the condition. The last feature of the syndrome known as
hypoplastic trachea simply means a very small trachea. Nearly all Bulldogs have
a smaller diameter trachea (windpipe) than other dogs. The hypoplastic trachea
is excessively narrowed even to the point of collapsing. It is often no wider
in diameter than a pencil in a full grown dog. This creates the problem of
creating additional negative pressure from the trachea making dogs more prone to
aspiration (inhaling food into the lungs). Aspiration then causes pneumonia
which the smaller trachea then makes more difficult to clear. No specific
treatment exists for hypoplastic tracheas. All of these conditions are
complicated by a dog that is too heavy! DON'T LET YOUR DOG GET TOO HEAVY.
Eye Conditions
Bulldogs are prone to several eye conditions. The most common is known as
"cherry eye" or more properly called
prolapse of the gland of the nictitans. This appears as a red, swollen mass
appearing out of the inside corner of the eye. The function of this gland is to
make tear fluid. The correct method for repairing this problem is to replace
the gland back to its proper position.
Keratitis Sicca, also
known as "dry eye", results from not enough tear fluid production. A dry eye
often becomes infected and develops a black pigment across the cornea and can
result in blindness if left untreated. Cyclosporine drops is the most commonly
prescribed treatment. Ophthalmologists believe that an increase in dry eye
occurs when cherry eyes are cut out instead of repaired.
Entropion/ Ectropion
is the rolling in/ rolling out of the upper and lower eyelids. This is commonly
an inherited problem. The result is that hairs rub on the eyes and cause
irritation resulting in corneal ulcers (scratches). These are best repaired
surgically to correct the respective problem.
Ectopiccilia/Dystichia
are hairs that grow out from along the eyelid margins or from within the
conjunctiva of the eye. These can cause irritation and corneal ulcers. These
can be treated either with cryosurgery or laser surgery. It is not uncommon to
need several treatments to resolve the problem.
Joint Conditions
Bulldog's hip xrays
will never win any awards for conformation. What would be considered "awful"
hips on almost any other breed will be acceptable on a bulldog. Occasionally,
we do run into a bulldog whose hips are without acetabulums (sockets) and these
dogs do show clinical problems. Luxating patellas
(knee caps) are also seen with the breed. This can be the slipping of the knee
cap either to the medial (inside) or lateral (outside) of the normal groove.
Bulldogs can also tear their anterior cruciate
ligaments (ACL's). A full tear will generally require surgery while
many Bulldogs with partial tears seem to do well with rest.
Hemivertebrae are
much less common and usually found as an incidental finding on xrays.
Hemivertebrae are vertebrae that are shaped more like triangles than blocks. A
more serious problem known as spinal bifida
involves deformities to the caudal aspect of the spinal column. The
significance of these lesions can be from mild to severe.
Ingrown tails can
become a serious problem. The tail grows backwards and down creating a deep
crevice that can become painful and infected. In severe cases the tails need
amputated. Milder cases require attention to keeping the area clean and dry to
maintain the pet's comfort.
Skin Conditions
The most common concern to Bulldog owners is keeping the face wrinkles clean and
dry. Many people have success with baby wipes, corn starch powder, neo-predef
powder, or if a yeast infection exists try malaseb pledgets. The staining seen in
the white face is many times caused by the iron in the tear fluid. For adult
dogs tetracycline binds up the iron and helps temporarily for severe staining.
This is NOT for use in puppies and will damage their teeth.
Another disorder seen in Bulldogs is the loss of hair on each side over the
flanks. While hypothyroid (low thyroid) should be ruled out with a blood test,
what we see more commonly is known as seasonal flank alopecia. This is the loss
of hair over the flanks usually associated with winter and shorter daylight.
Biopsy can confirm this and the condition is not serious and usually self
limiting. Some have seen results giving 6 mg of melatonin orally each day.
The ears are part of the skin, so make sure to keep them clean and free of
yeast. This is not unique to Bulldogs but is very important to their health.
Heart Defects
Most severe murmurs can be heard at 6 weeks of age. These can include
ventricular septal defects, pulmonic stenosis, aortic stenosis, and valve
problems. Some mild murmurs are "innocent" and go away as the puppy grows. Any
murmur heard can be better diagnosed with a cardiac ultrasound usually performed
by a veterinary cardiologist.
Breeding Bulldogs
Most breeders of Bulldogs use artificial insemination as opposed to natural
mating. This prevents a long "tie" which could result in overheating one or
both of the dogs. While pregnant watch closely for signs of excess water
retention. This can be picked up by ultrasound. Some breeders also note a
shiny purple appearance around the nipples as a warning sign. Low sodium diets
have helped anecdotally from some of our breeders as well as prescribing
hydrochlorthiazide as a diuretic (see your vet). A condition exists called "Anasarca"
or Congenital Lethal Edema which results in puppies that are swollen many times
normal size and weight (nicknamed walrus puppies). These puppies are too large
to deliver and while born alive, they seldom live more than several hours. The
cause is currently not known. Because of the increased risks in delivery for
Bulldogs, many breeders elect to have cesarean sections. Many have had
excellent success using Propofol, Isoflurane, IV fluids (0 .9 saline or 2.5 %
dextrose) and glycopyrrolate (does not cross blood brain barrier like
atropine). The most important factor for the puppies is aspirating off excess
fluid from the lungs with a bulb syringe.

Cystinuria -
Penn Veterinary Medicine-Cystinuria
Cystinuria is a genetic defect in which the kidney is not
able to process a basic amino acid.
This is a simple test in which you collect a urine sample and
mail to Penn Vet.
Interdigital cysts (swelling between the
toes)
From time to time Bulldogs may swell between the toes. Soak the paw in warm
Epsom salt water for 10-20 minutes for several days. Do not allow the dog to drink the water.
