Training methods and owner–dog interactions: Links with dog behaviour and learning ability

Abstract

The methods by which owners train their pet dogs range widely, with some exclusively using rewards, and others using a combination, or only punishment-based methods. This paper examines links between the way in which owners reported to have trained their dogs and observations of the dogs’ subsequent behaviour. It also explores associations between behaviour of owner and dog when tested in their own home. A total of 53 owners were surveyed about their preferred methods for training each of seven common tasks, and were each filmed interacting with their dog in a series of standardised scenarios. Dogs owned by subjects who reported using a higher proportion of punishment were less likely to interact with a stranger, and those dogs whose owners favoured physical punishment tended to be less playful. However, dogs whose owners reported using more rewards tended to perform better in a novel training task. Ability at this novel task was also higher in dogs belonging to owners who were seen to be more playful and who employed a patient approach to training. This study shows clear links between a dog's current behaviour and its owner's reported training history as well as the owner's present behaviour. High levels of punishment may thus have adverse effects upon a dog's behaviour whilst reward based training may improve a dog's subsequent ability to learn.

Effect of reinforcement, reinforcer omission and extinction on a communicative response in domestic dogs (Canis familiaris)

Abstract

There is a controversy about the mechanisms involved in the interspecific communicative behaviour in domestic dogs. The main question is whether this behaviour is a result of instrumental learning or higher cognitive skills are required. The present investigations were undertaken to study the effect of learning processes upon the gaze towards the human's face as a communicative response. To such purpose, in Study 1, gaze response was subjected to three types of reinforcement schedules: differential reinforcement, reinforcer omission, and extinction in a situation of “asking for food”. Results showed a significant increase in gaze duration in the differential reinforcement phase and a significant decrease in both the omission and extinction phases. These changes were quite rapid, since they occurred only after three training trials in each phase. Furthermore, extinction resulted in animal behaviour changes, such as an increase in the distance from the experimenter, the back position and lying behaviour. This is the first systematic evaluation of the behavioural changes caused by reward withdrawal (frustration) in dogs. In Study 2, the gaze response was studied in a situation where dogs walked along with their owners/trainers. These results show that learning plays an important role in this communicative response. The possible implications of these results for service dogs are discussed.
