High blood pressure is the colloquial term for hypertension. It happens when the arterial blood pressure of the dog is higher than usual for an extended period. If the cause of hypertension is another disease, then it is termed secondary hypertension. The term "primary hypertension" refers to the scenario when it is the disease. Hypertension may affect a few of the body systems of the dog, including the nervous system, heart, eyes, and kidney.
Dogs are much more affected by systemic hypertension than it
is commonly believed. The common symptoms shown by canines suffering from
hypertension are seizures, disorientation, dilated pupils, hemorrhage of the
eye, urine having protein or blood, nose bleeds, heart murmurs, an involuntary
oscillation of eyeballs, circling, blindness, retinal detachment, shrunk
kidneys or swollen kidneys, and the palpable thyroid gland.
Not much is known about primary hypertension causes in dogs.
There are instances where hypertension suffering breeding dogs have given birth
to babies already suffering from hypertension. It means that there could be a
genetic component. Approximately anywhere between 0.5 percent and 10 percent of
canines suffer from hypertension. The ages of dogs suffering from high blood
pressure range from two years to 14 years old. Almost 80 percent of dogs suffer
from secondary hypertension. The reasons could be many, including
hyperthyroidism, renal disease, and hormonal fluctuation., An important cause
of hypertension is diabetes, even though the latter is not much common in dogs.
It is important to take the dog to the veterinarian to get an expert opinion on
Blood pressure in dogs is frequently measured in the same manner as in humans. A kind of inflatable cuff will be fastened to the dog's tail or paw. The standard instruments used for measuring blood pressure will then check the blood pressure of the canine. It is vital that the dog should remain still for some period of time to get an accurate reading. Canines have different blood pressure readings compared to humans. There is minimal risk at 150/95 or below. No treatment is needed. Caution should be exercised when the reading is between 150/99 and 159/95. Intervention is generally not recommended during such readings. There is a risk of organ damage if the reading fluctuates between 160/119 and 179/100. Immediate treatment should be sought at 180/120. Steps must be taken to restrict other severe complications. About seven measurements are generally taken. The first of the seven measurements will be discarded as the dog gets excited during the first reading. In case the results are believed to be disputed, then the procedure must be repeated. The underlying reason for hypertension gets treated at first. If this is not done, the dog will be indefinitely be put on medication.
