A recent study published in Nature Communications found that all contemporary dogs have a common origin and emerged through a single domestication process of wolves. The research team analyzed the DNA of two prehistoric dogs from Germany and found that their genomes were the probable ancestors of modern European dogs.
Researchers found that puppies raised by attentive mothers were less likely to succeed in training programs. Those whose mothers nursed more often while standing up had lower graduation rates as adult guide dogs. The study suggests that minor obstacles can help offspring succeed later in life.
Researchers found that puppies raised by doting mothers were less likely to succeed in a training program to become guide dogs. The study suggests that guide-dog-training organizations can better identify dogs who are more likely to succeed by understanding the impact of maternal style on offspring behavior.
A new study of over 2,200 children finds no link between having a dog or cat and improved mental or physical health. While children from pet-owning families tend to have better general health, the association disappears when adjusting for other variables.
A UCLA researcher calculates that feeding pets contributes to climate change, with dogs and cats responsible for 25-30% of meat consumption's environmental impact in the US. The nation's 163 million dogs and cats eat about 19% as many calories as humans, with premium pet foods often containing more animal products.

According to Rutgers University researcher John McGann, humans can detect and discriminate an extraordinary range of odors, rivaling that of rodents and dogs. The human olfactory bulb is similar in size and number of neurons to other mammals, challenging the long-held misconception about human sense of smell.
A recent review by John McGann suggests that humans' ability to detect certain scents is superior to other animals, such as dogs. The study highlights the importance of smell in human communication and mate choice, challenging the long-held notion that humans have an inferior sense of smell.
Researchers from Oregon State University found that a family dog can improve physical activity, motor skills, and quality of life for children with disabilities. The study involved an eight-week intervention program where the child and dog participated in supervised physical activities and home exercises.

A large, wispy shell of gas, Sh2-308, is blown out by intense radiation from the extreme Wolf-Rayet star EZ Canis Majoris. The star's ongoing activity pushes the bubble to grow bigger and farther apart.
Cognitive biologists found dogs can correctly interpret cues by humans and find hidden food even if they cannot see it. Dogs adopt human perspectives by following gazes and understanding who knows what, enabling them to identify informants and successfully complete tasks.
A University of Alberta study found that babies from pet households had higher levels of microbes linked to lower allergy and obesity risks. Exposure to pets in the womb or after birth increased abundance of bacteria Ruminococcus and Oscillospira, which have been linked to reduced childhood allergies and obesity.

Researchers at the University of Helsinki have identified a novel gene associated with acute respiratory distress syndrome (ARDS) in Dalmatian dogs. The gene study found that the disorder results from a defect in an anillin protein which binds to actin, leading to abnormal regeneration capacity of the bronchiolar epithelium.
A study by Emory University used functional magnetic resonance imaging (fMRI) to analyze the brain activity of canine candidates. The results found that brain scans could predict which dogs would fail a rigorous service training program with a significant improvement in accuracy, helping organizations identify unsuitable dogs earlier. ...
Studies suggest that dogs and humans share a common type of social intelligence, which could help scientists better understand human evolution. Researchers found that dogs who excel in one social skill tend to perform well in related skills, similar to children, but not chimpanzees.
