Blood Pressure for Pets

Just like humans, it is important for your veterinarian to monitor your pet’s blood pressure.  Pets can have both high blood pressure (hypertension) and low blood pressure (hypotension).

If your pet has low blood pressure, their vital organs will be deprived of oxygen and nutrients.


Symptoms of low blood pressure could include the following:

  • Fainting or collapsing
  • Vomiting
  • Pale gums
  • Frequent urination and increased thirst
  • Fast, shallow breathing
  • Confusion


A pet with high blood pressure will present different symptoms.  It is important to treat high blood pressure as it can affect the heart, kidneys, eyes, and the nervous system.


Symptoms of high blood pressure to look out for include:

  • Seizures
  • Circling
  • Disorientation
  • Blindness
  • Dilated pupils
  • Retinal detachment
  • Hemorrhage of the eye
  • Blood in the urine
  • Protein in the urine
  • Bleeding from the nose
  • Swollen or shrunken kidneys
  • Heart murmurs
  • Weakness, on one side of the body or in the legs
  • Involuntary oscillation (rolling) of the eyeballs
  • Palpable thyroid gland (when hyperthyroid)
