ScienceDaily: Dog News Veterinary research and news on dogs as companions, canine health, wolf pack behavior and more. If it is news about dogs, you will find it here! Disagreeable people prefer aggressive dogs, study suggests Aggressive dog ownership is not always a sign of attempted dominance or actual delinquency. A new study finds that younger people who are disagreeable are more likely to prefer aggressive dogs, confirming the conventional wisdom that dogs match the personality of their owners. Modern dog breeds genetically disconnected from ancient ancestors Cross-breeding of dogs over thousands of years has made it extremely difficult to trace the ancient genetic roots of today's pets, according to a new study. Bioinformatics: We can learn a lot from other species Researchers have confirmed the long-held belief that studying the genes we share with other animals is useful. The study shows how bioinformatics makes it possible to test the fundamental principles on which life science is built. Medical research using dogs as models Dogs are among the best animals when it comes to providing models for better medical treatments in humans. Men can rest easy: Sex chromosomes are here to stay Fears that sex-linked chromosomes, such as the male Y chromosome, are doomed to extinction have been refuted in a new genetic study which examines the sex chromosomes of chickens. What is your dog thinking? Brain scans unleash canine secrets Researchers have developed a new methodology to scan the brains of alert dogs and explore the minds of the oldest domesticated species. The technique uses harmless functional magnetic resonance imaging, the same tool that is unlocking secrets of the human brain. The brain images of a fully awake, unrestrained dog, thought to be the first, opens up a door for understanding canine cognition and inter-species communication. Jurassic pain: Giant 'flea-like' insects plagued dinosaurs 165 million years ago It takes a gutsy insect to sneak up on a huge dinosaur while it sleeps, crawl onto its soft underbelly and give it a bite that might have felt like a needle going in -- but giant "flea-like" animals, possibly the oldest of their type ever discovered, probably did just that. Scientists confirm limited genetic diversity in the extinct Tasmanian tiger Scientists have confirmed the unique Tasmanian tiger or thylacine had limited genetic diversity prior to its extinction. Deadly cat disease: Effective treatment for bobcat fever University of Missouri veterinarian Leah Cohn, a small animal disease expert, and Adam Birkenheuer from North Carolina State University, have found an effective treatment for "bobcat fever" which is a deadly disease found in cats. With age comes greater success among hunting dogs In conducting research on hunting dogs in lowland Nicaragua, researchers have found that older and male dogs seem to enjoy better success rates than do younger and female dogs. Also, dogs are more suited to wildlife sustainability than other hunting options. Hunters with firearms tend to disproportionately hunt prey that lives in trees, including slow-breeding primates, whereas hunters with dogs tend to harvest relatively fast-breeding animals such as agoutis, pacas and armadillos. Too dog tired to avoid danger: Like humans, dogs engage in riskier behaviors ... Like humans, dogs engage in riskier behaviors when their self-control is depleted. Benefits of taking your dog to work may not be far-fetched Man?s best friend may make a positive difference in the workplace by reducing stress and making the job more satisfying for other employees, according to a new study. A number of environmental factors can affect the incidence of hip dysplasia i... Hip dysplasia (HD) in dogs is affected to a larger degree than previously believed by the environment in which puppies grow up. It is particularly during the period from birth to three months that various environmental factors appear to influence the development of this disease. During the puppy stage, preventive measures can therefore be recommended with a view to giving dogs disposed to the condition a better quality of life. New epilepsy gene located in dogs A new epilepsy gene for idiopathic epilepsy in Belgian Shepherds has been found in the canine chromosome 37. This research opens new avenues for the understanding of the genetic background of the most common canine epilepsies. The research also has an impact on the understanding of common epilepsies in humans. No fear of the 'big bad wolf:' Feeding habits of German wolves investigated Scientists have been investigating the feeding habits of wolves in the first eight years since their appearance in Germany. The results are reassuring: The proportion of livestock on the menu lies at less than one percent.
