Animal shelters can be stress-inducing environments for dogs because of the noise, social isolation and unpredictable housing (Hennessy et al., 2020). Dog enthusiasts and researchers alike have found that social interaction can help alleviate stress in dogs. The aim of this study was to understand dogs’ interaction preferences to improve their welfare in animal shelters. We hypothesized that there would be statistically significant differences between both the time dogs spent in dog-dog and dog-human interactions. The dogs’ interaction preferences were operationalized as the percentage of their play time they spent in dog-dog, dog-human and dog-environment interactions. A total of twelve dogs from the Animal Humane Society (AHS) in Golden Valley, Minnesota shelter participated as subjects in the study. The study ran for two weeks, and there were 2 sessions of 15 minute playgroups recorded at 9:00 AM, 11:40 AM and 2:20 PM. Each playgroup consisted of two to four dogs. We found statistically significant differences between the percentage of each dog’s individual time they spent in dog-human interactions, which is supported by the literature. Differences between the percentage of each dog’s time in dog-dog interactions were nearly, but not quite statistically significant. Further research is needed to determine if age, size and breed contribute to the dog’s interaction preferences. More research is also needed to determine whether individual differences in preference for dog-dog interaction exist between dogs, and how this knowledge can be applied to improve dogs’ welfare in shelters. Our research suggests that shelters should continue to provide dogs with play time to interact with humans, as it is helpful in alleviating the impact of environmental stressors.

Animal shelters are stressful environments for dogs and a plethora of research has been conducted on interventions aimed at improving the welfare of these animals. One type of intervention is social interaction, either between dogs and people or dogs and conspecifics. To investigate the types of social interaction dogs engage in and the impact of that contact on their welfare, 12 dogs were enrolled to participate in group sessions with other dogs, supervised by staff, in a shelter setting. There were three, 15-minute sessions per day across three days in which groups of two to four dogs were observed and recorded on video. These videos were then analyzed per dog for three types of interactions: dog-dog, dog-human, and dog-environment. It was found that the dogs spent significantly more time engaging with the staff members in the room than with conspecifics or the environment. Physiological measurements, including cortisol and S-IgA levels, were taken using urinary and fecal samples obtained both in the morning prior to these interaction sessions and after the final interaction of the day. No significant correlations were found between the amount of time that the dogs spent in each type of interaction and dogs’ cortisol or S-IgA levels. However, smaller statistical effects suggest that human interaction may correspond with decreased stress the day after interaction while conspecific interaction may be related to increases in stress the following day. Overall, these findings suggest that social interaction, particularly with people, may be beneficial, and should be further explored as a method to enhance the well-being of shelter dogs.

A handheld metal noisemaker known as a “clicker” is widely used to train new behaviors in dogs; however, evidence for the superior efficacy of clickers as opposed to providing solely primary reinforcement or other secondary reinforcers in the acquisition of novel behavior in dogs is almost entirely anecdotal. Three experiments were conducted to determine under what circumstances a clicker may result in acquisition of a novel behavior more rapidly or to a higher level compared to other readily available reinforcement methods. In Experiment 1, three groups of 30 dogs each were trained to emit a novel sit and stay behavior of increasing duration with either the delivery of food alone, a verbal stimulus paired with food, or a clicker with food. The group that received only a primary reinforcer reached a significantly higher criterion of training success than the group trained with a verbal secondary reinforcer. Performance of the group experiencing a clicker secondary reinforcer was intermediate between the other two groups, but not significantly different from either. In Experiment 2, three different groups of 25 dogs each were shaped to emit a nose targeting behavior and then perform that behavior at increasing distances from the experimenter using the same three methods of positive reinforcement as in Experiment 1. No statistically significant differences between the groups were found. In Experiment 3, three groups of 30 dogs each were shaped to emit a nose-targeting behavior upon an array of wooden blocks with task difficulty increasing throughout testing using the same three methods of positive reinforcement as previously. No statistically significant differences between the groups were found. Overall, the findings suggest that both clickers and other forms of positive reinforcement can be used successfully in training a dog to perform a novel behavior, but that no positive reinforcement method has significantly greater efficacy than any other.

Extensive research on the human mother-child relationship has led to the investigation of how relationships between dogs (Canis lupus var. familiaris) and humans compare. Studies suggest that dogs share a strong affectional bond with their owners and if put under stressful situations, exhibit key characteristics of attachment also observed in human babies. The goal of this review is to assess a variety of studies that explore different ways of measuring attachment between dogs and humans, beginning with a discussion of the Ainsworth Strange Situation Test (SST). The SST provides a foundation for the first studies that introduced attachment to the canine science field. It also aids in linking numerous attachment studies that look into different factors like the ages and physiology of the dogs, varying degrees of familiar people interacting with the dogs, owner-reported attitudes and behaviors, and the connection to wolves’ attachments with humans. I propose ways in which this particular scientific field can be enhanced and place a heavy emphasis on the implications of studying attachment particularly in shelter dogs. Synthesis and evaluation of the significant research on dog-human connections will not only lead to ways of fostering better relationships between owners and their dogs, but also allows us to better appreciate the special bond we have with dogs that lets us learn more every day.

A handheld metal cricket noisemaker known as a "clicker" is often used in dog training to teach dogs new behaviors; however, evidence for the superior efficacy of clickers as opposed to providing solely primary reinforcement or other secondary reinforcers in the acquisition of novel behavior in dogs is almost entirely anecdotal. We sought to determine under what circumstances a clicker may result in acquisition of a novel behavior to a higher level when compared to other potential reinforcement methods. In Experiment 1, three groups of 30 dogs each were trained to emit a novel sit and stay behavior with either the delivery of food alone, a verbal marker with food, or a clicker and food. The group that received only a primary reinforcer reached a significantly higher criterion of training than the group trained with a verbal secondary reinforcer. Performance of the group experiencing a clicker secondary reinforcer was intermediate between the other two groups, but not significantly different from either. In Experiment 2, three different groups of 25 dogs each were shaped to emit a nose targeting behavior and then perform that behavior at increasing distances from the experimenter using the same three methods of positive reinforcement used in Experiment 1.
