The findings confirm that thin myelin sheaths support nerve fiber function and survival, providing a potential marker for remyelination.
New research from the University of Portsmouth found that dogs produce more facial expressions when humans are looking at them. The study, led by Dr Juliane Kaminski, showed that dogs use these expressions to communicate with humans and not just due to excitement. Brow raising was the most commonly used expression in this research.

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.
Research by University of Cambridge suggests that external features cannot accurately predict breathing difficulties in pugs, French bulldogs and bulldogs.

A new study reveals that domesticated dogs and humans share a common genetic basis for social behavior, with unique genetic insertions associated with human-directed social behaviors in dogs. This finding challenges the conventional view of dog domestication and highlights the evolutionary conservation of sociability across species.
Researchers at Oregon State University identified a genetic marker linked to Williams-Beuren syndrome, a disorder characterized by hypersocial behavior. The study found domesticated dogs exhibit an exaggerated motivation to seek social contact compared to wolves, leading to prolonged proximity and gazing at humans.

The Puppy Training Supervisor Questionnaire (PTSQ) accurately identified 16.9% of dogs, helping trainers assess suitability early and improve training processes.
A new study confirms that wolves and dogs refuse to cooperate when they don't receive a reward, showing an innate sensitivity to inequity. The behavior is similar in both species, indicating it's not solely due to domestication.
Dog ownership has been found to encourage older adults to be more physically active, with an average of 22 minutes spent walking per day compared to non-owners. The study, published in BMC Public Health, also showed that dog owners had fewer sedentary events than non-dog owners.
