Peter Cook, Ashley Prichard, Mark Spivak, and Gregory S. Berns, Jealousy in dogs? Evidence from brain imaging

Abstract

Cook et al. investigated neural responses in domestic dogs in an experiment designed to elicit jealousy. Relative to a control condition, watching the dogs’ caregivers feed a fake dog activated the amygdala bilaterally. Dogs rated higher in dog-directed aggressiveness showed larger initial amygdala activation. Amygdala activity in this context is insufficient evidence to infer that the dogs experienced jealousy or even negative affect. The experimental design does not provide an adequate level of control to infer the presence of jealousy.
