Oxytocin receptor gene polymorphisms are associated with human directed social behavior in dogs (Canis familiaris).

The oxytocin system has a crucial role in human sociality; several results prove that polymorphisms of the oxytocin receptor gene are related to complex social behaviors in humans. Dogs' parallel evolution with humans and their adaptation to the human environment has made them a useful species to model human social interactions. Previous research indicates that dogs are eligible models for behavioral genetic research, as well.

Separation anxiety in dogs. The function of homeostasis in its development and treatment.

The model discussed here should help to provide an understanding of the range of stimuli that each dog needs for the maintenance of emotional homeostasis and the interplay between these stimuli and events in the dog's [table: see text] environment. In turn, this should aid in diagnosis and the setting of appropriate treatment plans.
