The odour of an unfamiliar stressed or relaxed person affects dogs' responses to a cognitive bias test

Z. Parr-Cortes, C. T. Müller, L. Talas, M. Mendl, C. Guest, N. J. Rooney

Published in 2024

Scientific article confirming that dogs can discriminate between human odors emitted during positive or negative emotions with no other cues. The results also show that olfactory signals of human stress affect dogs' behaviors when approaching a bowl of food placed in an ambiguous location and may affect their learning.

Family pigs' and dogs' reactions to human emotional vocalizations:a citizen science study

Fanni Lehoczki, Paula Pérez Fraga, Attila Andics

Published in 2024

Scientific article on a study testing whether the emotional contagion provoked in dogs by human sounds of distress is the result of their selection for cooperation with humans or is rooted in the universal signals of emotion. The authors compared the reactions of dogs and pigs to recordings of human crying and humming. Dogs became agitated when listening to crying, which the authors interpret as emotional contagion, while pigs were stressed by humming, which the authors interpret as neophobia (fear of the new).

Exploring the relationship between horse-owner attributes and their approach to horse training

E. Bartlett, E. J. Blackwell, L. J. Cameron, J. Hockenhull

Published in 2024

Scientific article aimed at identifying the factors that influence horse owners' choice of training approach. An online survey revealed that the choice of approach depended on several factors: age, gender, goals, activities, role in the industry and whether or not respondents had undergone training in animal behavior. Beliefs about the sentience and cognitive abilities of horses, and the use of scientific data were correlated with the likelihood of applying aversive methods.

Effects of single- or pair-housing on the welfare of shelter dogs: Behavioral and physiological indicators

Hecker G, Martineau K, Scheskie M, Hammerslough R, Feuerbacher EN

Published in 2024

Scientific article reporting that dogs housed in pairs in shelters, even for a short time, exhibit fewer stress-related behaviors (lip licking, whining, and ears back) than dogs housed individually. In addition, the urinary cortisol:creatinine levels in non-isolated dogs were lower.

A field approach to observing changes in behavioural welfare indicators over 2 years in stabled horses

A. Ruet, J. Lemarchand, C. Briant, C. Arnould, L. Lansade

Published in 2024

Article describing behavioral variations in stabled horses at 2-year intervals. Among the welfare indicators observed at the individual level, aggressive behaviour towards humans increased, while resting postures decreased. Other observed behaviours (stereotypies, withdrawal, alert and observation postures) did not change significantly over time.
