Forget the Treadmill. Get a Dog.

This is an article from the New York Times, written by my favorite author, Tara Parker-Pope.  This article shows the health benefits of having a pet in your life.  I hope you enjoy this article as much as I did.  It's always nice to be validated, especially in such an authority place like the New York Times!

<b> UNLEASHED </b> Among dog owners who went for regular walks, 60 percent met federal criteria for regular moderate or vigorous exercise, a new study says. 
 
Kevin Moloney for The New York Times UNLEASHED Among dog owners who went for regular walks, 60 percent met federal criteria for regular moderate or vigorous exercise, a new study says.
 

If you’re looking for the latest in home exercise equipment, you may want to consider something with four legs and a wagging tail.
Several studies now show that dogs can be powerful motivators to get people moving. Not only are dog owners more likely to take regular walks, but new research shows that dog walkers are more active over all than people who don’t have dogs.
One study even found that older people are more likely to take regular walks if the walking companion is canine rather than human.
“You need to walk, and so does your dog,” said Rebecca A. Johnson, director of the human-animal interaction research center at the University of Missouri College of Veterinary Medicine. “It’s good for both ends of the leash.”
Just last week, researchers from Michigan State University reported that among dog owners who took their pets for regular walks, 60 percent met federal criteria for regular moderate or vigorous exercise. Nearly half of dog walkers exercised an average of 30 minutes a day at least five days a week. By comparison, only about a third of those without dogs got that much regular exercise.
The researchers tracked the exercise habits of 5,900 people in Michigan, including 2,170 who owned dogs. They found that about two-thirds of dog owners took their pets for regular walks, defined as lasting at least 10 minutes.
Unlike other studies of dog ownership and walking, this one also tracked other forms of exercise, seeking to answer what the lead author, Mathew Reeves, called an obvious question: whether dog walking “adds significantly to the amount of exercise you do, or is it simply that it replaces exercise you would have done otherwise?”
The answers were encouraging, said Dr. Reeves, an associate professor of epidemiology at Michigan State. The dog walkers had higher overall levels of both moderate and vigorous physical activity than the other subjects, and they were more likely to take part in other leisure-time physical activities like sports and gardening. On average, they exercised about 30 minutes a week more than people who didn’t have dogs.

Does Your Pet Keep You Healthy?

Dr. Reeves, who owns two Labrador mixes named Cadbury and Bella, said he was not surprised.
“There is exercise that gets done in this household that wouldn’t get done otherwise,” he said. “Our dogs demand that you take them out at 10 o’clock at night, when it’s the last thing you feel like doing. They’re not going to leave you alone until they get their walk in.”
But owning a dog didn’t guarantee physical activity. Some owners in the study did not walk their dogs, and they posted far less overall exercise than dog walkers or people who didn’t have a dog.
Dog walking was highest among the young and educated, with 18-to-24-year-old owners twice as likely to walk the dog as those over 65, and college graduates more than twice as likely as those with less education. Younger dogs were more likely to be walked than older dogs; and larger dogs (45 pounds or more) were taken for longer walks than smaller dogs.
The researchers asked owners who didn’t walk their pets to explain why. About 40 percent said their dogs ran free in a yard, so they didn’t need walks; 11 percent hired dog walkers.
Nine percent said they didn’t have time to walk their dogs, while another 9 percent said their dogs were too ill behaved to take on a walk. Age of the dog or dog owner also had an effect: 9 percent said the dog was too old to go for walks, while 8 percent said the owner was too old.
“There is still a lot more dog walking that could be done among dog owners,” Dr. Reeves said.
And the question remains whether owning a dog encourages regular activity or whether active, healthy people are simply more likely to acquire dogs as walking companions.
A 2008 study in Western Australia addressed the question when it followed 773 adults who didn’t have dogs. After a year, 92 people, or 12 percent of the group, had acquired a dog. Getting a dog increased average walking by about 30 minutes a week, compared with those who didn’t own dogs.
But on closer analysis, the new dog owners had been laggards before getting a dog, walking about 24 percent less than other people without dogs.
The researchers found that one of the motivations for getting a dog was a desire to get more exercise. Before getting a dog, the new dog owners had clocked about 89 minutes of weekly walking, but dog ownership boosted that number to 130 minutes a week.
A study of 41,500 California residents also looked at walking among dog and cat owners as well as those who didn’t have pets. Dog owners were about 60 percent more likely to walk for leisure than people who owned a cat or no pet at all. That translated to an extra 19 minutes a week of walking compared with people without dogs.
A study last year from the University of Missouri showed that for getting exercise, dogs are better walking companions than humans. In a 12-week study of 54 older adults at an assisted-living home, some people selected a friend or spouse as a walking companion, while others took a bus daily to a local animal shelter, where they were assigned a dog to walk.
To the surprise of the researchers, the dog walkers showed a much greater improvement in fitness. Walking speed among the dog walkers increased by 28 percent, compared with just 4 percent among the human walkers.
Dr. Johnson, the study’s lead author, said that human walkers often complained about the heat and talked each other out of exercise, but that people who were paired with dogs didn’t make those excuses.
“They help themselves by helping the dog,” said Dr. Johnson, co-author of the new book “Walk a Hound, Lose a Pound,” to be published in May by Purdue University Press. “If we’re committed to a dog, it enables us to commit to physical activity ourselves.”

Good Dog, Smart Dog

 After reading this article, I have a new found appreciation for my little man.  I have always known that he was special, but I really never thought he could be as special as the dog in the article.  However, it seems I have very low expectations of my little man.

I only included an excerpt from this article.  There is more than what I have below.  Please go to the original site to read it in full.  Then, won't you come back and tell me if you agree or disagree with the article?

Life as a Labradoodle may sound free and easy, but if you’re Jet, who lives in New Jersey, there is a lot of work to be done.


Ross Macdonald

He is both a seizure alert dog and a psychiatric service dog whose owner has epilepsy, severe anxiety, depression, various phobias and hypoglycemia. Jet has been trained to anticipate seizures, panic attacks and plunging blood sugar and will alert his owner to these things by staring intently at her until she does something about the problem. He will drop a toy in her lap to snap her out of a dissociative state. If she has a seizure, he will position himself so that his body is under her head to cushion a fall.
Jet seems like a genius, but is he really so smart? In fact, is any of it in his brain, or is it mostly in his sniff?
The matter of what exactly goes on in the mind of a dog is a tricky one, and until recently much of the research on canine intelligence has been met with large doses of skepticism. But over the last several years a growing body of evidence, culled from small scientific studies of dogs’ abilities to do things like detect cancer or seizures, solve complex problems (complex for a dog, anyway), and learn language suggests that they may know more than we thought they did.
Their apparent ability to tune in to the needs of psychiatric patients, turning on lights for trauma victims afraid of the dark, reminding their owners to take medication and interrupting behaviors like suicide attempts and self-mutilation, for example, has lately attracted the attention of researchers.
In September, the Army announced that it would spend $300,000 to study the impact of pairing psychiatric service dogs like Jet with soldiers returning from Iraq and Afghanistan with post-traumatic stress disorder. Both the House and Senate have recently passed bills that would finance the training and placement of these dogs with veterans.
Hungarian researchers reported in a study last year that a guide dog for a blind and epileptic person became anxious before its master suffered a seizure and was taught to bark and lick the owner’s face and upper arm when it detected an onset, three to five minutes before the seizure. It is still somewhat mysterious how exactly dogs detect seizures, whether it’s by picking up on behavioral changes or smelling something awry, but several small studies have shown that a powerful sense of smell can detect lung and other types of cancer, as the dogs sniff out odors emitted by the disease.
Beyond these perceptual abilities, in which trainers can use the dogs’ natural instincts, some research has examined dogs’ actual cognitive ability, and found not just good doggie, but smart doggie.
“I believe that so much research has come out lately suggesting that we may have underestimated certain aspects of the mental ability of dogs that even the most hardened cynic has to think twice before rejecting the possibilities,” said Stanley Coren, a psychology professor at the University of British Columbia and an author of several books on dogs.
