They are prone to obesity, so they can quickly reach unhealthy weights; it is therefore important for Pug owners to make sure their pets get regular exercise. Due to their short snouts, Pugs are vulnerable to temperature extremes. It is important to make sure that they do not overheat in hot weather, and likewise they should not be left outside in cold weather.Pugs can also suffer from a chronic form of granulomatous meningoencephalitis (an inflammation of the brain) specific to the breed called Pug Dog Encephalitis (PDE). There is no known cause or cure for PDE, although it is believed to be an inherited disease. All dogs either die or are euthanised within a few months after the onset of clinical signs.
Pugs, along with other brachycephalic dogs (boxers, bulldogs), are also prone to hemivertebrae. The screwtail is an example of a hemivertebrae, but when it occurs in others areas of the spine it can be devastating, causing such severe paralysis that euthansia a serious recommendation.
