The researchers suggest that veterinarians should thoroughly examine dogs with behavior problems associated with noise for potential underlying pain.
Researchers analyzed ancient animal remains from Ceibal, Guatemala, revealing widespread Maya animal management earlier than thought. The findings suggest that captive animals played a significant role in the development of state society among the Maya.
Researchers analyzed animal remains from Ceibal, Guatemala, and found that dogs, turkeys, and cats were raised for ceremonial purposes, with dogs being traded across the landscape. The study sheds light on the role of animals in Maya civilization and challenges previous assumptions about their management.
Research reveals that wild mice living near humans in a Swiss barn underwent changes in behavior and physical appearance, including the development of white fur patches and shorter snouts. The study, led by Anna Lindholm, found that these changes occurred without human selection or breeding, highlighting the process of self-domestication.
Researchers surveyed 246 students before and after therapy dog sessions, finding significant reductions in stress and increased happiness. The benefits were equally distributed across both genders and lasted for at least 10 hours.

Researchers found a significant peak in dog cases of chocolate ingestion during the Christmas period. The study revealed that most cases involved small amounts of common festive chocolates, and owners should be prepared to provide information about the consumed amount and type of chocolate to help their vet take action.
Experts warn of a significant peak in chocolate poisoning risk for dogs during Christmas and Easter, due to increased accessibility of festive treats. Researchers analyzed 386 cases of dog intoxication from UK veterinary practices between 2012-2017, finding vomiting, heart rate increases, and agitation were common symptoms.

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.
A recent international multi-centre weight study found that overweight dogs can lose up to 11% of their bodyweight through specially-formulated diets. The study, published in PLOS ONE, also revealed improvements in activity and quality of life among dog owners.
Researchers used 3-D scans of fossil canid mandibles to determine whether they belonged to dogs or wolves. The study found that the skull changed shape but the evolution of the mandible lagged behind, making it unreliable for identifying early dog fossils.
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.
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 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.

A study using scat-sniffing research dogs helped scientists develop a plan to save reclusive jaguars, pumas, and other endangered carnivores by creating habitat corridors that connect protected areas. The model provides maximum habitat connectivity for all species while minimizing costs through privately owned lands and communities.
A new research study used a 'sniff-test' to evaluate dogs' ability to recognize themselves, confirming the hypothesis of self-cognition proposed by Dr. Cazzolla Gatti. The experiment found that dogs investigate their own odours longer when modified in an olfactory mirror test.
A University of Liverpool study found that dog walking motivates owners to do so due to feelings of happiness and well-being. Owners' motivations are contingent on their dog's enjoyment during the walk.
Scientists have found that trained dogs are more successful in detecting hermit beetle larvae than traditional methods. Using trained dogs can locate new populations, confirm the presence of target species, and map colonized trees accurately and efficiently.
