Pug health problems you can't ignore
Part of what makes the Pug so adorable is their flat face, but it can also cause a few problems. The shape of the face and the way the eyes protrude may make them prone to ulcerations if they touch the food bowl or anything else. This isn't a huge problem, just something to be aware of.
The Pug's face shape can be related to the problem of an elongated soft palate. In a Pug, this soft tissue at the back of the roof of the mouth can be longer than it should be, and can restrict the airway. The wheezing and odd breathing that is common in Pugs can be one symptom. It may also cause loud snoring and coughing up their food. Thankfully this can be corrected with surgery.
Sadly, there are two other Pug health problems that are much more serious in nature.
Pug Dog Encephalitis is an inflammation of the brain and generally starts when the dog is between 2 and 3 years old. There is currently not much information available about the disease, but it is always fatal. If your dog has seizures or has trouble walking and muscle weakness your vet should evaluate the Pug as these symptoms can be caused by problems other than Pug Dog Encephalitis.
The other is called hemi-vertebrae which is a congenital abnormality. If your dog has this abnormality you will probably have to euthanize him. While there isnt much you can do about this, you can avoid the heartbreak of adopting a dog with this condition. The abnormality can be detected by x-ray. What happens is that the vertebra do not mature properly, causing a spinal imbalance. As the dog grows this imbalance causes pressure on the spine which can lead to paralysis of the hind legs.
Pug health problems are something that any one considering getting a Pug should think about. Luckily, these problems are not common, so don't obsess about them too much when making your decision.
