One out of every three adults has high blood pressure or hypertension. As with humans, this health problem is seen in cats and dogs.Primary hypertension occurs when the blood pressure is higher than normal with no other cause. Secondary hypertension, however, occurs when the blood pressure is higher than normal as a result from a different disorder.Ordinarily, both a cat’s and dog’s blood pressure should be about 120/70, which is similar to the normal blood pressure of a human.

Different from humans, however, animals usually experience secondary hypertension as a result from another disorder instead of primary hypertension said Dr. Ashley Saunders, assistant professor at the Texas A&M College of Veterinary & Biomedical Sciences said.

“People get hypertension, so they can relate to it,” Saunders said. “The thing that is different between people and pets, though, is high blood pressure in pets is usually caused by something else.”

High blood pressure can be a sign of kidney disease, diabetes, endocrine disease, cancer in the adrenal glands, and central nervous system and brain disease. High blood pressure can also cause resinous problems such as blindness, seizures, and depression. Other signs include fainting, anxiety and restlessness at night, and loss of balance.

“Hypertension can result in blindness, fainting episodes, and can even contribute to kidney disease,” Saunders said.

Blood pressure on a pet is usually taken by shaving the underside of a paw and placing a cuff halfway down on the leg. Taking blood pressure on a pet is similar to that of a human, an ultrasound machine is used to listen to the pet’s blood flow while the cuff is inflated and then released. The animal’s blood pressure should be taken by a veterinarian. The main treatment for hypertension is medication.

“Hypertension in pets is totally different than people because it is normally caused by another disease and it needs to be medicated,” Saunders said. “People are used to hearing that they need to change their lifestyle, diet, and activity level when diagnosed with hypertension, but that does not work for pets--- medication is needed.”

Since hypertension is also a symptom for underlying problems, Saunders explained that it is important to get the pet’s blood pressure checked regularly. Middle aged pets and older, she added, are more susceptible to having diseases that would cause hypertension.

“Once the pet is middle aged or older, blood pressure should be taken regularly, at least once a year,” Saunders said. “This helps monitor their blood pressure and other possible disorders.”

I have found from years of world travel, meneitg new people every day as a tourguide in San Francisco, working with every age, gender and ethnic group around the Bay Area and the world, that it seems to be pretty clear: some people tune in to others and their emotions, others never will, can't do it. IN the latter category are a lot of males, especially those from US, Canada, Australia and northern Europe. From third-world countries, both men and women seem to be much more aware of others' emotions.So to me, it's clear, that it's both gender training and cultural expectations. If a ruthless emotionless male in northern countries can do much better in his profession or politics, then his parents, esp. the mother, will raise him to be so. If he's Sensitive , he can even be suspected of being gay! In fact, gay males around the San Francisco area seem to be inordinately sensitive and easily offended, and terribly concerned with others' emotions, to the point that it's self-defeating and emotionally crippling anxieties begin to mount as one focuses on others' emotions, those angry ones in particular. Learn to ignore, as the Chinese do!

It turns out our dogs have Oxidative Stress that could shorten their lives. There is canine supplement on the market to reduce oxidative stress in pets. Oxidative stress has been linked to 200 + diseases in mammals. http://goo.gl/rxZkw
