Hypertension in Dogs – What You Need to Know

High blood pressure isn’t just a human problem. Dogs can develop hypertension too, and it often sneaks up without obvious signs. If you’ve noticed your pup acting restless, panting more than usual, or you’ve heard the vet mention blood pressure, you’re in the right place. This guide breaks down the basics, shows you how to catch it early, and gives you easy steps to keep your dog’s heart happy.

How to Spot Hypertension Early

First off, there’s no simple “feel the pulse” test at home that works reliably for dogs. The gold‑standard is a veterinary blood pressure cuff, similar to the one used on people. Vets usually recommend checking your dog if they have one of these risk factors:

• Kidney disease or chronic renal issues
• Heart disease, especially if the heart sounds abnormal
• Hormonal problems like Cushing’s disease or hyperthyroidism
• Older age – senior dogs are more prone

If any of these apply, ask your vet for a baseline reading. Normal canine systolic pressure sits between 110 and 160 mm Hg. Anything consistently above 160 mm Hg flags hypertension.

Common Causes and What They Mean for Your Dog

Most cases tie back to an underlying health issue. Kidney disease is the biggest culprit because the kidneys help control fluid balance and blood vessel tone. Hormonal imbalances can also tighten blood vessels, pushing the pressure up. In rare cases, a tumor pressing on the adrenal gland can crank the numbers sky‑high.

Understanding the root cause is key because treating the underlying disease often brings the blood pressure back to normal. Your vet may run blood tests, urine analysis, or imaging to pinpoint the problem.

When the cause can’t be fixed, medication steps in. Drugs like amlodipine, an oral calcium‑channel blocker, are commonly prescribed for dogs. They relax the blood vessels, letting blood flow more easily. Your vet will start with a low dose and adjust based on follow‑up readings.

Alongside meds, lifestyle tweaks make a real difference. Keep your dog at a healthy weight – excess weight forces the heart to work harder. Offer low‑salt meals and avoid treats high in sodium. Regular, moderate exercise (like short walks or play sessions) improves circulation without overloading the heart.

Monitoring at home isn’t as precise as a vet’s cuff, but you can watch for warning signs. Sudden blindness, unexplained seizures, or a change in behavior can signal a blood‑pressure crisis. If you see any of these, call your vet right away.

In short, hypertension in dogs is manageable when you catch it early and follow a clear plan. Schedule regular blood‑pressure checks if your dog fits the risk profile, keep an eye on weight and diet, and stay on top of any prescribed medication. With a little attention, you’ll help your canine companion enjoy a longer, healthier life.
