Canine Dysautonomia

Dysautonomia is a condition characterised by a malfunctioning autonomic nervous system - the system responsible for involuntary functions like the contraction of smooth muscles, the heart rate, regulation of the pupil size, and so on.

Dogs suffering from the disease typically have dilated pupils that don't respond to light, decreased tear production, and elevated third eyelids. They may also suffer from vomiting or regurgitation due to decreased motility in the digestive tract.

In the majority of cases, the disease is incurable and fatal.
