Good Dogs Live Longer, Study Finds

Personality might play a big role in how long dogs live. Live fast die young might also apply to dogs, a study in the June issue of The American Naturalist suggests.Vincent Careau, of the University of Sherbrooke in Quebec, Canada, and his colleagues came to that conclusion by comparing numerous dog breeds based on their personalities. For example, poodles are ranked as 29 percent more docile than boxers, and Careau’s team found that poodles are four times more likely than boxers to live past age 10.

Beyond simply looking at aggressiveness, the researchers also found that the most obedient breeds, such as German Shepherds, Poodles, and Bichon Frises, live considerably longer than hard-to-train dogs such as Beagles and Pomeranians. Careau used personality data based on a 1995 psychology study that ranked dog personalities and also compared dogs of similar size.

Study Gives Scientists A Sense Of How Animals Bond

Scientists have pinpointed how a key hormone helps animals to recognise others by their smell.Researchers at the University of Edinburgh have shown that the hormone vasopressin helps the brain differentiate between familiar and new scents.The study, published in the journal Nature, suggests that when the hormone fails to function, animals are unable to recognise other individuals from their scent.

The ability to recognise others by smell is crucial in helping animals to establish strong bonds with other animals.The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC), may offer clues about the way people make emotional connections with others through smell and deepen our understanding of the role scent plays in memory.Many scientists think a failure in this recognition system in humans may prevent them from forming deep emotional bonds with others.

They are known as one of the deadliest creatures on Earth. But according to a shocking new study, great white sharks are also one of the most endangered. Wildlife experts say there are now fewer than 3,500 great whites left in the oceans, making them rarer than tigers.Yesterday, marine biologists called for an end to mankind’s long battle with sharks and demanded urgent action to prevent them going extinct.Great white sharks have a deserved reputation as ruthless and efficient killers, who use ambush techniques to attack fish, dolphins and seals from below.

Walk With Pet Dog Better Than Gym: Study

However, the human version may not be the most effective. A new study has shown that having a dog can successfully fill that requirement.

A survey of 5,000 Britons, conducted by pet healthcare company Bob Martin, showed that dog owners get more exercise walking their pet than people who go to gyms.Two dog walks a day each lasting 24 minutes and three longer walks a week each lasting 30 minutes give pet owners seven hours’ exercise a week, reports the Daily Express .

Those without a dog spend an average of just one hour and 20 minutes a week exercising by going to the gym or walking or jogging.And 47 per cent of non-pet owners admit they do no exercise.The survey revealed that 86 per cent of dog owners enjoy walking.On the other hand, only 16 per cent of gym users actively enjoy it, with almost 70 per cent seeing gym exercise as a chore.

New University Study Says Dogs Reduce Need for Meds

000752925

As pet lovers, we know having an animal around makes life better, but now there’s even more data to prove our point. Researchers at Chicago’s Loyola University announced this week that adults who use pet therapy while recovering from total joint-replacement surgery require 50 percent less pain medication than those who do not.

“Evidence suggests that animal-assisted therapy can have a positive effect on a patient’s psychosocial, emotional and physical well-being,” said Julia Havey, R.N., of Loyola University Health System. “These data further support these benefits and build the case for expanding the use of pet therapy in recovery.”

Animal lover Havey and colleague Frances Vlasses began raising puppies through the Canine Companions for Independence program more than 10 years ago, and based their claim on their observations of the field. As trainers, they absorb the costs associated with having the dogs, and teach them social etiquette until they reach about 15 months of age. The pups are then returned to the CCI’s regional training center for several months, where they are conditioned to become assistance dogs. There, they learn to assist with physical tasks, eventually understanding around 40 commands that help adults and children with special needs.

Based on their findings, Havey and Vlasses hope that animal-assisted therapy will eventually become universal in the healthcare field.
