The findings suggest that matching dogs with compatible roommates could alleviate stress and improve their adoptability, leading to better outcomes for animal shelters.
A new study reveals that praising and petting dogs enhances their learning success by reducing stress. Dogs who received a 'permissive' training style with praise and petting performed better than those in a 'controlling' style, which induced greater stress.
A nonrandomized controlled trial found that psychiatric service dogs partnered with usual care significantly reduced PTSD symptom severity and improved psychosocial functioning in veterans. This study suggests that psychiatric service dogs may be an effective complementary intervention for military service-related PTSD.

The analysis reveals that associations between dog diet and owner perceptions of health are minimal, with other variables such as age, breed, and veterinary care having stronger associations.
Researchers trained two dogs to imitate human actions using the Do as I Do training method, with successful replication from frontal and side angles. However, dogs struggled to imitate actions from overhead perspectives. This study expands knowledge on dog perception and interpretation of human actions.
