Pugs are prone to brachycephalic airway obstructive syndrome (BAOS) which causes respiratory distress in short-snouted breeds. Pugs have elongated palates. When excited, they are prone to "reverse sneezing" which causes them to quickly (and seemingly laboriously) gasp and snort. The veterinary name for this is pharyngeal gag reflex and it is caused by fluid or debris getting caught under the palate and irritating the throat or limiting breathing. Reverse sneezing episodes are usually not harmful, and massaging the dog's throat or covering its nose in order to make it breathe through its mouth can often shorten a sneezing fit.

Some pugs are also born with stenotic nares (pinched nostrils) which can inhibit their breathing. In serious cases, it makes breathing even more difficult and puts added pressure on the larynx. In some cases, the dog could pass out from blocked airways. If this happens, one should inquire with their veterinarian whether or not surgery is needed to open the nostrils.

Protruding eyes and eye prolapse is a common problem among pugs and other brachycephalic breeds and can be caused by a trauma to the head or neck. 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. If this is not done, the dog may develop a condition known as skin fold dermatitis.

An abnormal formation of the hip socket, known as hip dysplasia, affected nearly 64% of pugs in a 2010 survey performed by the Orthopedic Foundation for Animals; the breed was ranked the second worst-affected by this condition out of 157 breeds tested.

Pugs are one of several breeds that are more susceptible than other dogs to demodectic mange, also known as "demodex". This condition is caused when parasitic mites, that are often present in a dog's skin without causing symptoms, are allowed to do damage because their host has a weakened immune system. It is a problem for many young pugs, although not usually a major one, and is easily treatable, but some are especially susceptible and present with a systemic form of the condition. This vulnerability is thought to be genetic and breeders will avoid producing puppies from adults who have this condition.

In 2008, an investigative documentary carried out by the BBC found significant inbreeding between pedigree dogs, with a study by Imperial College, London, showing that the 10,000 pugs in the UK were so inbred that their gene pool was the equivalent of only 50 individuals.

Pugs can suffer from necrotizing meningoencephalitis (NME), also known as pug dog encephalitis (PDE), an inflammation of the brain and meninges. NME also occurs in other small dogs, such as the Yorkshire Terrier, Maltese, and Chihuahua. There is no known cure for NME, which is believed to be an inherited disease. Dogs usually die or have to be put to sleep within a few months of onset, which, in those susceptible to this condition, is mostly between six months and three years of age.

This breed, along with other brachycephalic dogs (e.g., boxers, bulldogs), are also prone to hemivertebrae. The curled tail of a British bulldog is an example of a hemivertebrae, but when it occurs not in the coccygeal vertebrae but in other areas of the spine, it can cause paralysis. The condition occurs when two parts of a spinal vertebra do not fuse properly while a young pug is still growing, resulting in an irregularly shaped spinal cavity which can put pressure on the spinal cord.

Health

Due to their athleticism and diverse breeding background, the breed tends to be hardy, with an average lifespan of 12 to 14 years, longer than many breeds of a similar size. There are some genetic conditions to be watchful for. The breed tends to suffer from bone diseases such as hip dysplasia, degenerative myelopathy and kneecap dislocation. The breed can also suffer from skin problems, such as mange and skin allergies, because of its short coat. Other health ailments seen in the breed include thyroid and congenital heart defects.

The breed tends to have a higher than average incidence of hip dysplasia. Culling for performance has helped eliminate this problem and others such as patella problems, thyroid dysfunction and congenital heart defects. American Pit Bull Terriers with dilute coat colors have not had a higher occurrence of skin allergies as other breeds. As a breed they are more susceptible to parvovirus than others if not vaccinated, especially as puppies, so vaccination is imperative beginning at 39 days old and continuing every 2 weeks until 4 months old. Then again at 8 months. Once a year after that, as recommend for all breeds.

They are prone to Demodex Mange due to culling for performance. There are two different types of Demodex Mange, namely Localized and Generalized Demodex. Although it is not contagious it is sometimes difficult to treat due to immunodeficiency in some puppies. The localized symptoms are usually loss of hair in small patches on the head and feet of the puppies. This type will usually heal as the puppies grow and their immune systems grow stronger. The second type which is Generalized Demodex mange is a more severe form of the sickness. The symptoms are more severe and include loss of hair throughout the entire body and the skin may also be scabby and bloody. Generalized are usually hereditary due to immunodeficiency genes that are passed on from Sire and Dam to their puppies. A simple skin scraping test will allow the vet to diagnose demodex mange. The most widely used method to treat Demodex Mange is ivermectin injections or oral medications. Since Demodex Mange lives in the hair follicles of the dog, Ivermectin will kill these mites at the source (please consult your vet before taking any action.).
