Just like with humans, blood pressure in dogs is a vital sign. It’s a measurement of how hard your dog’s blood is pushing against the walls of their arteries as it circulates. If a dog’s blood pressure is too high for too long, it can damage their organs.
So, what’s considered a normal blood pressure for dogs? And what can you do if your vet says your dog’s blood pressure is too high or too low? Keep reading to find out.
What is considered normal blood pressure for dogs?
Like people, dogs can have high blood pressure, low blood pressure, or blood pressure within the normal range.
A normal blood pressure reading for a dog is between 110/60 and 160/90. The top number, or systolic pressure, measures the pressure in the arteries when the heart beats. The bottom number, or diastolic pressure, measures the pressure in the arteries between heartbeats.
It’s worth noting that a dog’s blood pressure can fluctuate temporarily. Stress and excitement at the vet’s office, for example, can elevate blood pressure. That’s why it’s important that your vet take accurate and consistent measurements.
High Blood Pressure (Hypertension) in Dogs
Just as in people, high blood pressure can cause significant health problems for dogs.
A dog is usually diagnosed with high blood pressure, or hypertension, if their systolic blood pressure (the top number) is consistently above 165 mmHg or their diastolic pressure (the bottom number) is consistently above 100 mmHg.
There are two types of hypertension in dogs: primary and secondary. Primary hypertension, meaning there’s no underlying condition causing the high blood pressure, is rare in dogs. Secondary hypertension, which is caused by another health problem, is much more common.
If high blood pressure goes untreated for too long, it can damage a dog’s organs, especially the eyes, kidneys, heart, and brain. Because of this, it’s a good idea to make sure your vet checks your dog’s blood pressure at their regular checkups, especially as they get older.
What causes high blood pressure in dogs?
High blood pressure in dogs can be caused by a number of underlying medical conditions, certain medications, breed predilections, and age.
Underlying medical conditions
Secondary hypertension, or high blood pressure caused by another condition, may be the result of:
- Cushing’s disease
- Hyperthyroidism
- Adrenal gland tumors
- Kidney disease
- Diabetes
- Certain medications
Breed and age
While any dog can develop high blood pressure, some breeds are more prone to it than others. High blood pressure is also more common in older dogs.
What are the symptoms of high blood pressure in dogs?
When a dog has high blood pressure, symptoms may include:
- sudden blindness
- seizures
- nosebleeds
- heart murmurs
If you notice any of these symptoms, you should seek veterinary care for your dog right away. Catching high blood pressure early can help you manage the condition and protect your dog’s health.
The Bottom Line
Regular veterinary checkups, including blood pressure monitoring, are essential for managing high blood pressure in dogs. If your vet identifies hypertension, work closely with them to determine the best treatment plan for your canine companion.
As a dog owner, you play a crucial role in managing your pet’s health. By staying informed and proactive, you can dramatically improve your dog’s quality of life and ensure they live a long, happy, and healthy life.
