The compressed facial structures of brachycephalic breeds
lead to increased resistance in their airways.
The brachycephalic breeds
of dogs are considered highly susceptible to chemodectomas (JOHNSON, 1968; DEAN & STRAFUSS, 1975; KISSEBERTH, 2001), and there is an apparent male predisposition (JOHNSON, 1968; CAPEN, 2002); during this study, only male dogs were diagnosed with aortic body tumors.
For example, brachycephalic breeds
such as the bulldog are especially susceptible to heat stroke.
Cherry eye has been reported as a disease of animals younger than one year and breeds like Cocker Spanial, Beagle, Boston terrier, Lhasa Apso, English Bulldogs, Pekingese, Boston Terriers, Basset Hounds, Shih Tzus, and brachycephalic breeds
are predisposed (Slatter, 2003; Fossum, 2013).
Among brachycephalic breeds
, not all dogs will necessarily suffer from the syndrome, also known as congenital obstructive upper airway disease.
Entropion is most commonly a genetic condition with brachycephalic breeds
, such as Persians and Himalayans, at higher risk because of their skull conformations," says J.
However, some breeds are prone to weakness in tissue such as Neapolitan Mastiffs, American Cocker Spaniel, Lhasa Apsos and many brachycephalic breeds
Some breeds are also predisposed--those who cannot dissipate heat as efficiently, for example, brachycephalic breeds
Densely coated cats (Himalayans and Persians, for example), whose bodies are less able to dissipate heat are also at elevated risk, as are brachycephalic breeds
, those with flat faces and short noses, who may lack sufficient nasal space to allow the cooling of inhaled air.
The condition is commonly seen in Cocker spaniels, Terriers, Poodles and other brachycephalic breeds
