Among the respondents, 75.7% expressed concern about the welfare of shrimp, believing that they can experience fear (63.0%), pain (84.0%), and pleasure (47.7%). The latter finding suggests a relative reluctance to recognize positive feelings in shrimp. Regarding eyestalk ablation, 81.7% of respondents were unaware of the procedure, but after a brief explanation, 81.3% considered it unacceptable, with 84.0% believing that shrimps suffer from the practice. Most respondents associated terms such as \"painful, cruel, suffering, mercantilist, disrespectful, and mutilating\" with the practice of ablation. Furthermore, by using Pearson's chi-square test, it was observed that gender, age, region, education, socio-economic status, profession, and frequency of consumption may be related to the respondents' opinions about shrimp welfare and their perception of shrimp sentience. Therefore, by recognizing that public concern drives changes in production methods, increasing knowledge about shrimp sentience and farming practices can help advance socially acceptable methods.</span></p></div>","PeriodicalId":17567,"journal":{"name":"Journal of Veterinary Behavior-clinical Applications and Research","volume":"71 ","pages":"Pages 41-56"},"PeriodicalIF":1.8,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139069513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While this phenomenon has been observed in several mammal species, findings in domestic dogs have been inconsistent, although this issue has strong relevance in dog training. The aim of this study was to assess the effects of SNC in two responses that had already been studied in this species, but with an increase in the methodological rigor and variations in the experimental conditions to examine the generalizability of the phenomenon. To this end, experimental dogs experienced a preshift phase in which they received a high-value reward (liver), followed by a postshift phase in which they obtained a low-value reward (dry dog food), and then a reshift phase in which the high-value reward was available again. Control dogs received dry food in all phases. The results show a contrast effect on the behavior of following human pointing to obtain food (study 1). On the contrary, there were no differences in problem-solving behavior after the de- and re-evaluation of the reward during a nonsocial task (study 2). The results support that SNC is not a consistent phenomenon in pet dogs. It is possible that certain characteristics of dogs such as the great availability of high-value rewards in their daily lives could attenuate the effects of a reduction in incentive value.</p></div>","PeriodicalId":17567,"journal":{"name":"Journal of Veterinary Behavior-clinical Applications and Research","volume":"72 ","pages":"Pages 18-27"},"PeriodicalIF":1.8,"publicationDate":"2023-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139069241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, fourteen horses were participated in a series of behavior tests with one rider to determine the effects of androstenone on behaviors.

In the riding test without obstacles, horses exhibited a significantly reduced frequency of undesirable behavior when treated with androstenone (<em>P</em> &lt; 0.05).

This study included 19 shelters, with dogs housed for at least two months. Management data were collected with the Shelter Quality protocol, and emotional indicators were evaluated with the Qualitative Behavior Assessment (QBA) methodology. By grouping the 12 QBA descriptors and the SQP indicator “barking level,” five profiles were obtained that describe the valence of the dogs’ emotional states: positive, interactive, hesitant, aggressive, and negative. These profiles were used in MCA, generating two principal components that each had two associative patterns; inverse correspondences with the management variables “population size,” “mortality rate,” “food management,” “number of dogs per pen,” and “walking routine” were explored. Positive emotional states were observed in shelters providing weekly or daily walks, housing dogs in individual pens, and feeding them twice a day.

A questionnaire targeting small animal veterinarians was applied via online or printed forms. Multinomial logistic regression analysis was applied to examine the relationship between the opinions of veterinarians about the prohibition/restriction of dog breeds and their opinions on the level of aggression of these breeds. While 29.23% of veterinarians approved the prohibition of dangerous dog breeds, 45.64% of veterinarians stated that dogs of these breeds should be restricted. However, 25.13% of the participants did not approve of breed-specific legislation for whatever reason.

It was followed by Dogo Argentino (15.17%), Bull Terrier (14.20%), Rottweiler (10.44%), American Staffordshire Terrier (7.74%), Japanese Tosa (7.69%), and Fila Brasileiro (7.63%), respectively.

As a result, veterinarians were of the opinion that individuals of dog breeds that can frequently exhibit aggression resulting in severe injury or death to the victim should be restricted instead of banning them.

However, assessments of the prevalence of the problems vary greatly depending on the source of information and questions the study employs. The most accurate estimate of prevalence is likely to be obtained through study of a representative sample of dog owners. The aim of the current questionnaire study was therefore to investigate the prevalence of and risk factors for dog behavior problems by analyzing the responses of a representative sample of Danish dog owners. To the authors’ knowledge, this kind of study, involving a representative sample of dog owners, has only been conducted once before in the state of Victoria, Australia. We found that 34% (<em>n</em> = 172) of Danish dog owners surveyed (<em>n</em> = 502) perceived their dog to have one or more problems related to behavior. The most common problems were related to fear (<em>n</em> = 90 dogs, 18%) and disobedience (e.g., jumping up at people and not coming when called <em>n</em> = 54 dogs, 11%). The most common fear problem was fear of noises (<em>n</em> = 51 dogs, 10%). Among aggression problems, the most common by far was inter-dog aggression (<em>n</em> = 40 dogs, 8%). We identified dog, owner, and management variables as possible risk factors for dogs with behavioral problems. Increasing dog age was associated with lower levels of problems connected with disobedience. Dog disease within the last year was associated with a higher risk of problems with fear and aggression. Living in an apartment, as opposed to a (sub)urban house or farm/house in the countryside, was associated with a raised risk of fear problems. Daily off-leash time on walks was associated with a lower risk of problems related to aggression and disobedience. Finally, a higher frequency of training with the dog, either at home or in dog training classes, was associated with a lower risk of problems related to all three of fear, aggression, and disobedience.
