Effects of a Brief Separation From the Owner While in the Home Environment: Comparison of Fearful and Control Dogs

Abstract

ABSTRACT Separation from their owner is stressful for some dogs. Studies examining this phenomenon are usually carried out in novel places. However, given that separation distress can also impact the behavior and welfare of dogs in their home environment, it is critical to study them in this context as well. Our first aim was to evaluate the reactions of dogs to a brief separation from their owner in the home. Secondly, we aimed to examine differences in the reactions of dogs classified as fearful, without (n = 27) and with (n = 17) aggressive responses, as well as controls (n = 28). All dogs were adults, from various breeds and mixes, and lived as pets. Each dog’s behavior was evaluated across three phases: (1) 2 min interaction with owner (baseline), (2) 3 min separation from the owner (alone), and (3) 2 min after the owner returned (owner return). We measured exploration as well as affiliative and stress behaviors. The results show that dogs explored the environment more in phase 1, directed more behaviors toward the door through which the owner had left in phase 2, followed the owner leaving at the end of phase 2, and greeted them when they returned in phase 3. Dogs also spent more time near the owner after their absence in phase 3 than in phase 1. A decrease in exploration triggered by the absence of the owner in phase 2 and a lack of full exploration recovery in phase 3 were observed as possible indicators of stress. No differences were found between fearful dogs and controls. The results indicate that it is possible to evaluate dogs’ reactions to separation from their owner in a more naturalistic context. This could aid in the development of strategies to improve separation-related problems in dogs and thus improve their welfare and quality of life.
