Paroxysmal sympathetic hyperactivity (PSH) is a syndrome that causes episodes of increased activity of the sympathetic nervous system. Hyperactivity of the sympathetic nervous system can manifest as increased heart rate, increased respiration, increased blood pressure, diaphoresis , and hyperthermia . [ 1 ]
Canine cognitive dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. [1] CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life.
Surviving dogs developed seizures, fecal and urinary incontinence, confusion, memory loss, seromas, emotional dysregulation, focal neurologic symptoms, weakness, and weight loss. [ 19 ] 40% of surviving dogs did not have a reduction in existing aggression, and some dogs' aggression worsened after the procedure. [ 19 ]
Treatment involves insulin replacement therapy, [95] and use of a diet high in fiber and complex carbohydrates. [96] Oral diabetes medications cannot be used for dogs because none repair or surmount the permanent damage to the beta cells of the pancreas.

Sympathetic failure manifests itself as orthostatic hypotension and anhidrosis. Orthostatic symptoms, which include lightheadedness, dizziness, or syncope upon standing and loss of postural reflex tachycardia, occur in 78% of patients. [1] Dry eyes and mouth are symptoms of parasympathetic failure caused by secretomotor dysfunction.
Horner's syndrome, also known as oculosympathetic paresis, [1] is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged. The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk.
A pug named Vito has been crowned best in show at the 92nd annual National Dog Show – the first time a pug has won the title in at least two decades.
The sympathetic nervous system's activation provides for these needs. A similar example involving fight is of a cat about to be attacked by a dog. The cat shows accelerated heartbeat, piloerection (hair standing on end), and pupil dilation, all signs of sympathetic arousal. [23] Note that the zebra and cat still maintain homeostasis in all states.
