High Blood Pressure in Dogs Symptoms and Treatment

High Blood Pressure

The blood pressure in dogs is a rare condition and is shown in two ways: as primary hypertension or secondary hypertension. If you have diagnosed your dog this health problem. It will be crucial to find out what the risk factors that cause it, the symptoms it presents or the treatment to follow.

High Blood Pressure

The hypertension blood is a sustained elevation of systolic or diastolic pressure or, in other words, persistent high pressure. High blood pressure is called primary, essential, or idiopathic when another disease does not cause it. This type of hypertension is very common in people is very rare in dogs. Conversely, when another disease causes the rise in pressure it is known as secondary hypertension. This is the most frequent form in dogs.

Although this disease is not routinely diagnosed in veterinary consultations, its potential effects are very dangerous as it affects different organs and may even cause death. Among the damages that high blood pressure can cause in dogs are:

Causes and risk factors

Primary or idiopathic hypertension occurs due to unknown causes. It has been speculated that it may be of genetic origin, but there is no conclusive evidence. In any case, the incidence of this type of hypertension is so low in dogs that no research is done. On the other hand, other diseases mainly cause secondary canine hypertension. Dogs most prone to hypertension are the elderly and obese. The diseases that most frequently raise the blood pressure of dogs are:

Symptoms of High Blood Pressure in Dogs

Dogs with primary hypertension rarely have symptoms. Those with secondary hypertension the most common form may have one or more of the following symptoms:

  • Hemorrhage within the eyeball
  • Blindness
  • Dilated pupils
  • Retinal detachment
  • Nystagmus (abnormal and frequent movements of the eyeball)
  • Blood in the urine
  • Proteins in the urine
  • Kidneys of abnormal size (enlarged or reduced)
  • Nasal bleeding
  • Disorientation
  • Loss of coordination
  • Partial paralysis of the limbs
  • Seizures
  • Heart murmur
  • Enlarged thyroid gland


The diagnosis of arterial hypertension in dogs is similar to the method used for humans: an occlusive cuff is used to measure the pressure in the artery distal to the cuff. Usually blood pressure is measured dogs in one leg or tail. To obtain accurate and accurate results it is necessary to measure the pressure several times.

Also other procedures are more complicated or invasive so they are not normally used in veterinary practices, but in research institutions or in large veterinary hospitals. Unfortunately, the diagnosis of hypertension is not routinely done in veterinary clinics because the procedure is difficult and can give erroneous results with ease, since most dogs get nervous during the diagnosis.

That is why blood pressure is accustomed to measuring only when there is reason to believe that the dog suffers from hypertension. It is important to keep in mind that the blood pressure of the greyhounds is usually slightly higher than that of the other breeds of dogs.

Treatment of hypertension in dogs

The primary pressure should be treated with drugs to help reduce blood pressure and by proper diet should produce veterinary, according to the specific needs of the patient. On the contrary, in secondary hypertension it is necessary to treat the underlying causes. If you do not treat the diseases that cause it, it makes no sense to try to lower your blood pressure. Each treatment, therefore, will be different according to the causes that cause the pressure rise.

In some cases, it may be necessary to intern the dog in a hospital or veterinary clinic. In most cases, it is often necessary to modify the diet and follow a recommended exercise program, in addition to prescription drugs to treat underlying conditions.
