High Blood Pressure in Dogs

High Blood Pressure in Dogs

While uncommon, high blood pressure or hypertension is a serious condition that can affect our canine companions. Today, our Rancho Cucamonga vets share the main causes and symptoms of high blood in dogs as well as how it is diagnosed and treated.

Hypertension: High Blood Pressure In Dogs

High blood pressure in dogs is not very common, it only happens in a small percentage of dogs. For a dog's blood pressure to be considered high, it must be consistently higher than normal dog blood pressure (above 150mmHg).

A normal dog's blood pressure range is quite wide and goes higher than the healthy range for humans. A normal dog's blood pressure will range anywhere from 110/60 to 160/90.

Causes of High Blood Pressure in Dogs

The first is high blood pressure caused by hereditary factors. This makes up only about 20% of cases of high blood pressure in dogs.

The second type is called secondary hypertension. This is high blood pressure caused by an underlying condition. Most cases of high blood pressure in dogs are secondary. Because of this, it is important to understand the signs and symptoms of high blood pressure in dogs.

Risk factors for hypertension in dogs can include increased age, obesity, underlying diseases such as kidney disease or Cushing's disease, and certain medications. It is important for pet owners to be aware of the potential for high blood pressure in their dogs and to take their pets for regular check-ups with their veterinarian to monitor for any signs of hypertension or underlying health issues.

Breeds More Susceptible to High Blood Pressure

Certain dog breeds may be more prone to developing high blood pressure than others. One example is the Cavalier King Charles Spaniel, which is known to have a high incidence of chronic hypertension due to their predisposition to heart disease.

Other breeds that may be at increased risk for high blood pressure include Dachshunds, Miniature Schnauzers, Boxers, and Shih Tzus. 

The Typical Signs of High Blood Pressure in Dogs

Signs of high blood pressure in dogs are easily missed by pet parents. Noticing and treating high blood pressure in dogs is made even more difficult by the fact that they have no way to tell us if they are feeling sick. That is why it is important to know and to be able to recognize the symptoms of high blood pressure so that you can plan with your vet to combat it.

Some of the things to look out for are:

  • Weakness
  • Loss of sight
  • Disorientation
  • Nosebleeds
  • Seizures
  • Heart murmurs
  • Enlarged kidneys
  • Rapid breathing

If your dog is showing one or more of the symptoms above it's time to book an appointment with your veterinarian. While these symptoms aren't always a result of high blood pressure they do indicate that your pup is likely suffering from an underlying health problem that should be addressed.

In cases of secondary hypertension, early detection could help lead to the diagnosis and treatment of a developing health concern before it becomes severe. In most cases, health issues are most effectively treated when caught early.

Taking Your Dog's Blood Pressure

The answer to 'How to take a dog's blood pressure?' is unfortunately not as simple as it is for people. While we just have a cuff that slips around our arm, the method for dogs requires a different method. 

Veterinarians use a specially designed inflatable cuff that is placed around the dog's leg or tail to take a reading. If your vet is concerned about your dog's blood pressure further diagnostic testing may be required.

Diagnosing High Blood Pressure in Dogs

High blood pressure in dogs is typically diagnosed through a combination of physical examination, blood pressure measurements, and blood tests. During a physical examination, your dog's veterinarian may check for signs such as increased heart rate, abnormal heart sounds, or swollen blood vessels.

Blood pressure measurements can be taken using a non-invasive technique, such as an inflatable cuff placed around the dog's limb or tail. Blood tests can also be performed to evaluate for underlying causes of high blood pressure, such as kidney disease or hormonal imbalances.

If your dog is diagnosed with hypertension, the underlying cause should be identified and treated as soon as possible. Your dog may require ongoing monitoring and treatment in order to manage their blood pressure.

Treating Hypertension in Dogs

Treatment for your dog's high blood pressure will depend on the type of high blood pressure your dog suffers from.

Dogs with hereditary high blood pressure — the rarer of the two, can be treated with a change in diet and more exercise throughout the day. If that doesn't lower your dog's blood pressure, your vet may prescribe medication.

Dogs with secondary hypertension will likely receive treatment for the cause of hypertension, as opposed to hypertension itself. However, your vet may prescribe medication for hypertension in conjunction with other treatments.

Often, the first signs of hypertension wind up being asymptomatic, so you must schedule regular vet visits if you notice any signs of high blood pressure in your dog.
