Understanding High Blood Pressure in Dogs
High blood pressure, also known as hypertension, is a condition that can affect dogs, just like humans. It is important for dog owners to be aware of the signs and risk factors associated with high blood pressure in dogs.
Definition and Causes
High blood pressure in dogs is defined as an elevated blood pressure measurement above the normal range. The cause of primary hypertension in dogs is unknown, while secondary hypertension is often due to underlying conditions such as kidney disease, adrenal gland disease, diabetes mellitus, pheochromocytoma, or central nervous system disease (VCA Hospitals). Dogs with renal failure, for example, have been shown to have a high incidence of hypertension.
Certain dog breeds may have a higher predisposition to hypertension. Sight hounds, especially deerhounds, normally have higher blood pressure than other breeds. Additionally, overweight dogs may experience elevated blood pressure levels (AKC Canine Health Foundation).
Risk Factors in Dogs
Several risk factors can contribute to the development of high blood pressure in dogs. These include:
- Underlying diseases: High blood pressure in dogs is often associated with underlying diseases such as chronic kidney disease, adrenal gland disease, diabetes mellitus, pheochromocytoma, or central nervous system disease (VCA Hospitals).
- Breed-specific considerations: Certain breeds, such as sight hounds, may naturally have higher blood pressure levels compared to other breeds. Additionally, overweight dogs may be at a higher risk of developing hypertension (AKC Canine Health Foundation).
- Age: Hypertension in dogs is more common in older dogs, often associated with underlying diseases. However, it can also occur in younger dogs with developmental kidney abnormalities.
Recognizing the signs and symptoms of high blood pressure in dogs is crucial for early detection and proper management. In the following section, we will explore the various signs and symptoms associated with high blood pressure in dogs.
Signs and Symptoms of High Blood Pressure
High blood pressure, or hypertension, in dogs can manifest in various signs and symptoms, providing important clues for early detection and intervention. It’s crucial for dog owners to be aware of these indicators to seek veterinary care promptly. The signs and symptoms of high blood pressure in dogs can be categorized into ophthalmologic, cardiac, neurological, and renal signs.
Ophthalmologic Signs
Signs of high blood pressure in dogs can often be observed in the eyes. Ophthalmologic changes may include intraocular bleeding and retinal detachment, which can lead to sudden blindness. Retinal hemorrhage, sudden blindness, dilated pupils, and blood in the eye are among the specific signs to watch for.
Cardiac Signs
High blood pressure can also affect the cardiovascular system of dogs. Cardiac signs may include the presence of a heart murmur and congestive heart failure (AKC Canine Health Foundation). Monitoring for heart murmurs and seeking veterinary attention if they are detected can be crucial in identifying potential hypertension.
Neurological Signs
Neurological signs can occur as a result of high blood pressure in dogs. A stroke caused by hypertension can lead to changes in gait and balance, sudden blindness, and altered mental activity (AKC Canine Health Foundation). Recognizing these neurological changes is essential for early intervention and management.
Renal Signs
The kidneys are also susceptible to the effects of high blood pressure in dogs. Renal signs may include the presence of protein in the urine and progressive signs of renal failure. Blood in the urine and proteinuria can be indicative of hypertension. Monitoring your dog’s urination habits and noting any abnormalities can help in detecting potential renal involvement.
Being vigilant for these signs and symptoms of high blood pressure in dogs is crucial for early detection and effective management. If you notice any of these indicators, it’s important to consult with a veterinarian for proper diagnosis and appropriate treatment. Early detection and intervention can help mitigate the potential complications associated with hypertension in dogs.

Diagnosis of High Blood Pressure in Dogs
To diagnose high blood pressure, or hypertension, in dogs, veterinarians employ various diagnostic methods. These methods help assess the blood pressure levels and identify any underlying conditions that may contribute to hypertension.
Physical Examinations
During a physical examination, veterinarians will assess your dog’s overall health and look for any signs or symptoms that may indicate high blood pressure. They will examine the heart, lungs, eyes, and kidneys for any abnormalities. This examination helps identify potential areas of concern that may require further evaluation.
Blood Pressure Readings
Measuring blood pressure is a critical step in diagnosing high blood pressure in dogs. Blood pressure readings are typically performed using a Doppler device or an oscillometric blood pressure monitor. The Doppler device uses sound waves to detect the blood flow in the arteries, while oscillometric monitors use an inflatable cuff to measure blood pressure.
A blood pressure reading consists of two numbers: systolic pressure and diastolic pressure. In dogs, systolic blood pressure is the most commonly measured parameter. Dogs with systolic blood pressures exceeding 150 mmHg may require further evaluation and, in some cases, medication.
Blood Tests
Blood tests play an essential role in diagnosing high blood pressure in dogs. These tests help identify any underlying conditions that may be contributing to hypertension. For example, dogs with renal failure often have hypertension. In fact, one study found that 93 percent of dogs with renal failure had high blood pressure (AKC Canine Health Foundation).
Blood tests may include a complete blood count (CBC), blood chemistry panel, and urinalysis. These tests help assess the overall health of your dog, including kidney function and the presence of any underlying diseases or abnormalities.
Once high blood pressure is diagnosed in your dog, appropriate treatment options can be discussed. Medications, such as angiotensin-converting enzyme (ACE) inhibitors, angiotensin II receptor antagonists (ARBs), beta blockers, diuretics, and calcium channel blockers, are commonly used to manage hypertension in dogs. The specific treatment plan will depend on the severity of hypertension and any underlying conditions.
Regular veterinary check-ups, especially for senior dogs or those with known risk factors, are crucial for early detection and management of high blood pressure. Monitoring your dog’s blood pressure, coupled with appropriate lifestyle changes and management of underlying conditions, can help ensure their overall well-being and minimize the potential complications associated with hypertension in dogs.
Treatment Options for High Blood Pressure
When it comes to treating high blood pressure in dogs, a combination of medication, lifestyle changes, and regular monitoring is often necessary to manage the condition effectively.
Medication
Medication plays a crucial role in managing high blood pressure (hypertension in dogs). Commonly prescribed drugs for dogs with high blood pressure include:
- Angiotensin-converting enzyme (ACE) inhibitors: These medications help relax and dilate blood vessels, reducing blood pressure.
- Angiotensin II receptor antagonists (ARBs): These drugs block the action of angiotensin II, a hormone that constricts blood vessels.
- Beta blockers: Beta blockers work by reducing the heart rate and the force of heart contractions, thereby lowering blood pressure.
- Diuretics: Diuretics help increase urine production, reducing fluid volume and blood pressure.
- Calcium channel blockers: These medications relax and widen blood vessels, allowing for better blood flow.
The specific medication and dosage will depend on the individual dog’s condition and response to treatment. It’s important to work closely with a veterinarian to determine the most appropriate medication for your dog’s needs.

Lifestyle Changes
In addition to medication, certain lifestyle changes can help manage high blood pressure in dogs. These may include:
- Diet modifications: A balanced diet that is low in sodium and high in essential nutrients can help maintain a healthy blood pressure. Consult with your veterinarian to determine the most suitable diet for your dog.
- Exercise: Regular exercise, tailored to your dog’s fitness level, can help promote cardiovascular health and control blood pressure. Ensure that exercise is gradual and appropriate for your dog’s breed, age, and overall health.
- Stress reduction: Minimizing stress and providing a calm environment for your dog can contribute to better blood pressure management. Create a peaceful and comfortable space for your furry friend.
- Weight management: Maintaining a healthy weight is important for dogs with high blood pressure. If your dog is overweight, work with your veterinarian to implement a weight loss plan that includes a combination of diet and exercise.
Monitoring and Follow-Up
Regular monitoring is essential to ensure that treatment is effective and that your dog’s blood pressure remains within a healthy range. This may involve periodic visits to the veterinarian for blood pressure readings, as well as routine blood tests to evaluate the overall health of your dog.
The treatment goal for dogs with high blood pressure is to achieve a systolic pressure of 140mmHg or less and a diastolic pressure of 90mmHg or less. Regular laboratory testing is essential to monitor medication side effects and disease progression. Your veterinarian will determine the appropriate frequency of follow-up visits based on your dog’s condition.
By combining medication, lifestyle changes, and ongoing monitoring, you can effectively manage high blood pressure in dogs. Remember to work closely with your veterinarian to develop a comprehensive treatment plan tailored to your dog’s specific needs. With proper care and attention, you can help your furry companion live a healthy and comfortable life.

During these visits, your veterinarian can assess your dog’s overall health, including monitoring their blood pressure. Regular monitoring allows for early detection of any changes or abnormalities that may indicate the development of high blood pressure. It is recommended to schedule routine check-ups at least once a year, or more frequently for older dogs or those with underlying health conditions.
Managing Underlying Conditions
Managing underlying conditions that can contribute to high blood pressure is another important preventive measure. Certain diseases, such as kidney disease or Cushing’s disease, can increase the risk of hypertension in dogs. By working closely with your veterinarian, you can develop a comprehensive treatment plan to manage these conditions effectively, which, in turn, can help prevent the development or progression of high blood pressure.
It’s crucial to follow your veterinarian’s recommendations regarding medication administration, dietary modifications, and any lifestyle changes that may be necessary. Regular follow-up appointments will allow your veterinarian to monitor your dog’s condition closely and make any necessary adjustments to the treatment plan.
Breed-Specific Considerations
Certain dog breeds may be more prone to developing high blood pressure. For example, Cavalier King Charles Spaniels, Dachshunds, Miniature Schnauzers, Boxers, and Shih Tzus have a higher incidence of chronic hypertension due to predispositions to heart disease. If you own a dog from one of these breeds, it’s important to be particularly vigilant and proactive in monitoring their blood pressure and overall health.
Regular veterinary check-ups and screenings are especially crucial for these breeds to detect any signs of high blood pressure early on. By being aware of your dog’s breed-specific risks, you can work closely with your veterinarian to implement preventive measures tailored to their needs.
By prioritizing regular veterinary check-ups, managing underlying conditions, and being mindful of breed-specific considerations, dog owners can take proactive steps to prevent high blood pressure in their furry companions. Early detection and intervention are key, as they can lead to the timely diagnosis and treatment of any underlying health concerns before they become severe. Together with your veterinarian, you can create a preventive care plan that helps ensure your dog’s long-term health and well-being.
