=== Physical characteristics === Pugs, like other short-snouted breeds, have elongated palates. When excited, they are prone to 'reverse sneezing' which causes them to quickly (and seemingly laboriously) gasp and snort. If this happens, one should inquire with their veterinarian whether or not surgery is needed to modify the breathing passages.Eye prolapse is a common problem among Pugs and other brachycephalic breeds (see brachycephalic airway obstructive syndrome) and can be caused by a trauma to the head or neck, or even by the owner using a tight leash instead of a harness. While the eye can usually be pushed back into its socket by the owner or by a vet, veterinary attention is usually advisable. If the prolapse happens on a regular basis, the Pug might require surgery.Pugs have many wrinkles in their faces, so owners will often clean inside the creases to avoid irritation and infection.
