My 12 week-old English Bulldog, Harley,
makes a lot of noise when she breathes. It
seems her nostrils are very narrow. Is this
normal? Harley also snores when sleeping.
Is this common in Bulldogs?
Many short-nosed breeds (boxers, bulldogs,
pugs, Boston terriers) have breathing
difficulties due to their strange anatomy. These
dogs are referred to as brachycephalic breeds,
and their breathing difficulties are caused by a
condition called brachycephalic airway
syndrome. This syndrome consists of multiple
anatomic and acquired abnormalities, including
narrow nostrils. Narrow nostrils in a dog make
it difficult for air to pass through the nasal
passages, analogous to breathing through a
straw. Snoring may be a result of a lengthy
soft palate. The soft palate is the fold of tissue
which separates the nasal and oral cavities.
Snoring may be normal in any dog or human,
but excessive snoring and difficulty breathing
may indicate a problem. These abnormalities, if
severe enough, can cause secondary changes
to the windpipe (trachea) and the voice box
(larynx). However, the nostrils and palate can
be surgically corrected to help prevent these
secondary changes. Since affected animals
may pass these traits on to their offspring, it is
advisable to spay or neuter affected animals.
Brachycephalic breeds have even more
difficulty breathing in hot weather and should
not be left unattended for long. It is important
to keep these breeds thin because obesity
makes breathing difficult. If you are concerned
your dog may have brachycephalic airway
syndrome, ask your veterinarian.
