The aim of the present study was to evaluate whether dogs that exhibit stereotypy also show higher behavioral persistence in an extinction-learning task. Thirteen pet dogs with stereotypy and 13 breed-matched control dogs were assessed on a resistance to extinction test. Each dog was trained for 40 trials using a food reinforcer to nose-touch the(More)
Approximately 4 million dogs live in animal shelters each year. However, understanding and measuring the welfare of these kenneled dogs presents a challenge. One way to determine welfare is by assessing how stay at the shelter influences physiology, immune function, and behavior of the dogs. Prior research, from all of these domains, has not resulted in(More)
The aim of this study was to develop a humane alternative to the traditional remote devices that deliver punishers contingent on home-alone dog barking. Specifically, we evaluated the use of remote delivery of food contingent on intervals of not barking during the pet owner's absence. In Experiment 1, 5 dogs with a history of home-alone nuisance barking(More)
The present study evaluated whether environmental variables can reinforce and maintain canine stereotypic behavior and whether the removal of these variables can reduce the rate of the behavior. We first present an online survey in which the owners were asked to report the environmental antecedent and consequent events related to stereotypic behavior in(More)
Previous empirical evaluations of training programs aimed at improving dog adoption rates assume that dogs exhibiting certain behaviors are more adoptable. However, no systematic data are available to indicate that the spontaneous behavior of shelter dogs has an effect on adopter preference. The aim of the present study was to determine whether any(More)
In a sequence of studies, we evaluated 2 behavioral interventions designed to decrease undesirable in-kennel behaviors of shelter dogs. In Experiment 1, we compared the efficacy of a simple pairing of person with food (response-independent treat delivery) to an increasing interval differential-reinforcement-of-other-behavior (DRO) procedure and a control(More)
This study involved examining the ability of a postadoption intervention to reduce returns of newly adopted dogs to shelters by encouraging physical activity between adopters and their dogs. Guardians in the intervention group received emails with dog behavior and human activity advice as well as invitations to join weekly dog walks. Both the intervention(More)
25 The aim of the present study was to evaluate whether dogs that exhibit stereotypy also show 26 higher behavioral persistence in an extinction-learning task. Thirteen pet dogs with stereotypy 27 and 13 breed-matched control dogs were assessed on a resistance to extinction test. Each dog 28 was trained for 40 trials using a food reinforcer to nose-touch(More)
The data on the dynamics of prehospital mortality in acute coronary failure (ACF) and myocardial infarction (MI) depending on the improvement in medical service in the prehospital stage of treatment are presented. The research showed that prehospital mortality in ACF and MI accounts for 75% of the total mortality. Among deaths registered in the prehospital(More)
