Health
Since Pugs lack longer snouts and prominent skeletal brow ridges, they are susceptible to eye injuries such as proptosis, scratched corneas, and painful entropion. They also have compact breathing passageways, leaving many prone to breathing difficulties or unable to efficiently regulate their temperature through evaporation from the tongue by panting. A Pug's normal body temperature is between 101 °F (38 °C) and 102 °F (39 °C). If this temperature rises to 105 °F (41 °C), oxygen demand is greatly increased and immediate cooling is required. If body temperature reaches 108 °F (42 °C), organ failure can occur. Their breathing problems can be worsened by the stresses of travelling in air cargo, which may involve high temperatures. Following the deaths of Pugs and other brachycephalic breeds, several airlines either banned their transport in cargo or enacted seasonal restrictions. Pugs that live a mostly sedentary life can be prone to obesity, though this is avoidable with regular exercise and a healthy diet. The median life span of Pugs is 11 years, which is in line with other breeds of the same size.
