Tibetan Terriers are a relatively healthy breed, thanks to breeders dedicated to their health and welfare.

Neuronal Ceroid Lipofuscinosis

Neuronal Ceroid Lipofuscinosis (NCL), is an autosomal recessive disorder affecting the eyes and the nervous system.

Abnormalities are often observed starting at 4-6 years. These include mental changes such as the development of aggressiveness toward people and/or other dogs; nervousness; changes in eating habits; loss of both behavioral and house training. Affected dogs exhibit a mildly uncoordinated gait with occasional stumbling and crossing over. The lack of coordination becomes more severe as the disease progresses. They often have difficulty jumping up onto surfaces and going up or down stairs. In the later stage of the disease affected dogs fall over often and have difficulty getting back on their feet. Visual abnormalities maybe be noticed such as impaired vision under dim light conditions. Mild seizures that are often unrecognized by the owner are common as the disease progresses.

Due to the late onset of the disease, a dog may not show any symptoms until after their breeding career is finished. Fortunately, thanks to research at the University of Missouri a genetic marker was finally found and as of late January 2010 there is a DNA test available.

Hip dysplasia

Canine hip dysplasia is a disease involving abnormal formation of the hip joints. Progressive and crippling arthritis may result. CHD is thought to be of polygenetic inheritance with environmental influence.


Patellar Luxation

Patellar luxation is the dislocation of the patella (kneecap). The condition can result from trauma that caused the knee to be forced out of normal alignment, but is more often genetic in nature.



A cataract is defined as any spot on the lens, regardless of size, that does not allow light to pass through. Cataracts can be confined to a single area within the lens or affect the entire structure. They were identified in dogs as early as 1925.


Progressive retinal atrophy

Progressive Retinal Atrophy (PRA) is an inherited form of eye disease causing blindness. The first symptom is usually the loss of night vision. This can appear as early as 8 months of age but often does not show up until the dog is 3 to 5 years old.
