Two studies present evidence suggesting that exposure to dogs during pregnancy and early childhood may reduce the risk of developing eczema and asthma. While exposure to dog allergens can exacerbate symptoms in children with allergies, non-allergen-related factors associated with dogs may provide a protective effect.
A team of researchers from the University of Wisconsin-Madison reports that in long-lived animals, renewed but thin myelin sheaths are enough to restore the impaired nervous system. 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.
Researchers found that wolves excelled in cooperative behavior compared to dogs, even when raised together under similar conditions. The study suggests that domestication may not have increased tolerance and cooperation among dogs as expected.
A genetic mutation has been identified as a key factor in the development of intervertebral disc disease (IVDD) in short-legged dog breeds, including dachshunds and French bulldogs. The discovery provides a valuable tool for owners, breeders, and veterinarians to mitigate the risk of IVDD and related spinal cord disease.
A world-first study published in The Lancet Psychiatry suggests that basic mental health training for managers can significantly improve workers' mental wellbeing.

A University of New South Wales researcher has uncovered documents that suggest Teddy Evans, Scott's second-in-command, may have been responsible for his leader's death and that of four others. Evans' actions, including stealing rations and failing to pass on orders, are believed to have contributed to the tragedy.
A study led by the University of Arizona found that dogs with leash aggression had higher levels of total vasopressin, while those without exhibited higher oxytocin and oxytocin-to-vasopressin ratios. This supports the idea that oxytocin may help inhibit aggression in dogs.
Researchers funded by Morris Animal Foundation found that the rabies vaccine reduces mortality from all causes in dogs by 56 percent, particularly among young dogs. This non-specific protective effect may have implications for human medicine as well.

Researchers describe three cases of eyeworm infection in UK dogs with recent travel to mainland Europe. The parasite, Thelazia callipaeda, is found in fruit flies and can infect dogs, cats, and humans, posing a significant threat to the UK canine population.
A new study from Linköping University finds that dogs' willingness to collaborate with humans is linked to genetic variations in the oxytocin receptor gene. The researchers discovered a possible explanation for why dogs differ in their ability to work together, which may have contributed to human selection during domestication.
A study by researchers at the University of Veterinary Medicine in Vienna found that wolves demonstrate a better understanding of cause and effect than dogs. In experiments, wolves correctly identified causal cues such as noise produced by an object containing food when shaken, whereas dogs did not.
