2. How to Measure Dog Blood Pressure at Home
Equipment Needed
- Household Electronic Sphygmomanometer: A device designed for measuring blood pressure, available from pet supply stores or veterinary clinics.
Steps to Measure Blood Pressure
- Acclimate Your Dog to the Cuff:
- Get your dog accustomed to the cuff by having them wear it for short periods, about 5 minutes at a time.
- Reassure and calm your dog during this process to alleviate any fear or anxiety.
- Repeat this acclimation process until your dog is comfortable with the cuff.
- Create a Calm Environment:
- Conduct the measurement in a quiet room free from distractions such as other animals, loud noises, or active appliances.
- Allow your dog to relax in the room for 5-10 minutes before taking measurements to ensure they are calm and their blood pressure is stable.
- Position Your Dog Correctly:
- Have your dog lie down in either a ventral (on their belly) or lateral (on their side) position, whichever they find more comfortable.
- Positioning the dog in these supine positions helps keep the cuff close to the heart, resulting in more accurate readings.
- Take Multiple Measurements:
- Place the cuff on one of your dog’s legs, either a front leg or hind leg.
- Press the start button on the sphygmomanometer and take readings every few minutes for about 10-15 minutes.
- Ensure consistency by using the same leg and maintaining the same position for all readings.
- Obtain at least seven readings, discarding the first measurement to allow the dog to settle into the process.
- Calculate Blood Pressure:
- Review the readings and discard any outlier measurements that are significantly higher or lower than the others.
- Calculate the average of the consistent readings to determine your dog’s systolic and diastolic blood pressure.
Regularly measuring and recording your dog’s blood pressure at home can provide valuable information to your veterinarian and help in the ongoing management of hypertension. Keeping a log of readings can help track trends and make informed decisions about your dog’s health care.
3. Dog Blood Pressure Classification and Normal Values
Hypertension Classification

- How They Work: ACE inhibitors block the conversion of angiotensin I to angiotensin II, a substance that narrows blood vessels. This results in relaxed blood vessels and lower blood pressure.
- Uses: Often used for dogs with chronic kidney disease or heart disease.
-
Calcium Channel Blockers
- Common Drugs: Amlodipine
- How They Work: These medications prevent calcium from entering the cells of the heart and blood vessel walls, leading to lower blood pressure.
- Uses: Primarily used in cases of severe hypertension or when other medications are ineffective.
-
Beta-Blockers
- Common Drugs: Atenolol, Propranolol
- How They Work: Beta-blockers reduce heart rate and the heart’s output of blood, which lowers blood pressure.
- Uses: Typically prescribed for dogs with concurrent heart disease.
-
Diuretics
- Common Drugs: Furosemide, Spironolactone
- How They Work: Diuretics help the kidneys remove excess sodium and water from the body, reducing blood volume and pressure.
- Uses: Often used in dogs with fluid retention issues, such as those with heart failure.
