Dogs' special relationship to humans may go back 27,000 to 40,000 years, according to genomic analysis of an ancient Taimyr wolf bone. Earlier genome-based estimates have suggested that the ancestors of modern-day dogs diverged from wolves no more than 16,000 years ago, after the last Ice Age.
Brown Dog Ticks can drive homeowners and their canines to extreme measures. But new research may help alleviate the problem: homeowners can use pesticides to control the ticks, but "the vacuum is your best friend," the researchers say.
Gray wolves in Yellowstone National Park have given researchers the first scientific evidence from wild mammals that living in a group can lessen the impacts of a chronic disease. The research also is one of the first studies to measure the costs of infected non-human individuals of any species on members of their group.
Dogs who suffer with separation anxiety become more optimistic when taking the animal equivalent of Prozac during behavioral treatment, according to the results of an innovative new study. Canine separation-related problems -- also described as separation anxiety or separation distress -- are among the most common behavioural complaints of dog owners. But the issue of using psychoactive medication to help pets with behavioural problems is a widely debated one. Treatment with psychoactive medication in parallel with a behavior modification plan is well documented, but it is unknown if this is associated with an improvement in underlying emotion or mood, or simply an inhibition of the behavior.
