Evolution of facial muscle anatomy in dogs
Contributor(s):: Kaminski, J., Waller, B. M., Diogo, R., Hartstone-Rose, A., Burrows, A. M.
Domestication shaped wolves into dogs and transformed both their behavior and their anatomy. Here we show that, in only 33,000 y, domestication transformed the facial muscle anatomy of dogs specifically for facial communication with humans. Based on dissections of dog and wolf heads, we show that...
Dog breed differences in visual communication with humans
Contributor(s):: Konno, A., Romero, T., Inoue-Murayama, M., Saito, A., Hasegawa, T.
Domestic dogs (Canis familiaris) have developed a close relationship with humans through the process of domestication. In human-dog interactions, eye contact is a key element of relationship initiation and maintenance. Previous studies have suggested that canine ability to produce human-directed...
Justice for all? Children's moral reasoning about the welfare and rights of endangered species
Contributor(s):: Ruckert, J. H.
This study reports children's developing moral concerns for endangered animals. Three questions were addressed: (1) Do children conceive of not harming an endangered animal as a moral obligation? (2) Do children use biocentric (nature-centered) moral reasoning? and (3) Does a developmental shift...

When dogs look back: inhibition of independent problem-solving behaviour in domestic dogs ( Canis lupus familiaris) compared with wolves ( Canis lupus)
Contributor(s):: Udell, M. A. R.
Domestic dogs have been recognized for their social sensitivity and aptitude in human-guided tasks. For example, prior studies have demonstrated that dogs look to humans when confronted with an unsolvable task; an action often interpreted as soliciting necessary help. Conversely, wolves persist...

Dogs that perform best for guarding and herding livestock have different behavioural profiles, as stated by the authors: 'herding dogs are selected to show hunting behaviours, such as eye, stalk, grip or heel. Guarding dogs are selected to show more of the wild ancestor's puppy-like or juvenile...

A comparison of pet and purpose-bred research dog ( Canis familiaris) performance on human-guided object-choice tasks
Contributor(s):: Lazarowski, L., Dorman, D. C.
Several studies have shown that domestic dogs respond to human social cues such as pointing. Some experiments have shown that pet dogs outperformed wolves in following a momentary distal point. These findings have lent support to the hypothesis that domestication is responsible for domestic dogs'...
A fresh look at the wolf-pack theory of companion-animal dog social behavior
Contributor(s):: Kerkhove, W. van
A popular perspective on the social behavior of dogs in multiple-dog households sees the dogs' behavior as reflecting the sociobiological laws of the rigidly structured dominance hierarchy that has been described for wolf packs. This view suggests that aggression problems among dogs are natural...
Human interaction as environmental enrichment for pair-housed wolves and wolf-dog crosses
Contributor(s):: Mehrkam, L. R., Verdi, N. T., Wynne, C. D. L.
Private nonhuman animal sanctuaries are often financially limited in their ability to implement traditional environmental enrichment strategies. One possible solution may be to provide socialized animals with human interaction sessions. However, the merit of human interaction as enrichment has...
