The effective use of psychoactive medications in avian patients is limited by the lack of controlled studies. Appropriate dosages, predictable therapeutic effects, pharmacokinetic data, and information about toxicity are often lacking. A variety of psychoactive agents have been used in avian patients to treat disorders such as feather chewing or picking, self-mutilation of soft tissue, and anxiety, but larger clinical trials and placebo-controlled trials are needed to determine efficacy and safety of these agents. The decision to use psychoactive medication in an avian patient and the choice of medication should be based on existing data for the particular species and an understanding of the drug’s mechanisms and indications. For any behavioral disorder, the need for pharmaceutical intervention requires the following: a thorough physical examination and baseline pretreatment laboratory testing, as indicated by physical examination findings and symptoms; an established diagnosis based on complete behavioral and medical histories; a signed owner consent statement; a behavior modification plan with appropriate environmental modifications; knowledge of the drug, side effects, indications, and mechanisms of action; and realistic expectations about treatment outcomes. Use of antipsychotic agents, serotonin reuptake inhibitors, tricyclic antidepressants, opioid antagonists, benzodiazepines, and hormonal therapies are described.  相似文献

Among 26 dogs greater than or equal to 10 years old, the most frequent owner complaints relating to behavioral problems were destructive behavior in the house (n = 10), inappropriate urination or defecation in the house (n = 10), and excessive vocalization (n = 7). The most frequent behavioral diagnoses were separation anxiety (n = 13) and breakdown of housetraining (n = 6). Most of the behavioral problems in the 26 dogs began after the dogs reached the age of 10 years, and most of the dogs had been owned for many years without having behavioral problems. Few behavioral problems in old dogs had a medical basis. Most cases of inappropriate urination or defecation in the house were not related to urinary or fecal incontinence, but were exacerbated by problems such as degenerative joint disease and renal disease. Behavioral therapy is appropriate for behavioral problems in old dogs, and, taking into account an old dog's health and physical limitations, techniques used are the same as for younger dogs.  相似文献

The practice of behavioral dermatology encompasses the management of any dermatologic condition for which there is a substantial behavioral or emotional component. Commonly recognized behavioral dermatoses such as acral lick dermatitis, psychogenic alopecia, and hyperesthesia are syndromes rather than discrete diagnoses. Successful patient management is dependent upon integrating physiological, social, and environmental factors which contribute to the clinical manifestation of behavioral dermatoses.  相似文献

Pheromonotherapy seems to be a new therapeutic approach allowing practitioners to tackle the treatment of behavioral disorders in a natural, specific, and safe way. Although the efficacy of pheromones has been assessed in some specific behavioral problems, it seems that their range of action could cover the wide field of reduction of stress. Therefore, the use of pheromones should not be reduced to treatment of behavioral disorders (potentially associated with psychotropes or a behavioral modification program) but should be included in a strategy of improving the welfare of pets in veterinary structures (during examination and hospitalization) and in breeding networks (separation from the mother and transport). Moreover, further studies may allow the veterinary practitioner to use pheromone analogues in the field of diagnostics to determine the behavioral status of a pet (e.g., anxious or not, dominant or not). Pheromonotherapy is at its beginning, and the use of pheromones in various fields of medicine is heartening.  相似文献

OBJECTIVE: To determine the prevalence of age-related behavioral changes, namely impairment, in a randomly chosen population of dogs. DESIGN: Age-stratified cohort study. ANIMALS: 97 spayed female and 83 castrated male dogs that were 11 to 16 years old. PROCEDURE: Data on possible impairment in 4 behavioral categories (ie, orientation in the home and yard, social interaction, house training, and sleep-wake cycle) linked to cognitive dysfunction were obtained from dog owners, using a structured telephone interview. Hospital records of dogs had been screened to exclude dogs with dysfunction in organ systems that may cause behavioral changes. Dogs with behavioral impairment were those with > or = 2 signs of dysfunction within a category. Dogs with impairment in 1 category were considered mildly impaired and those with impairment in > or =2 categories were considered severely impaired. RESULTS: Age by sex interactions for dogs with impairment in any category were not significant, and, therefore, data on castrated males and spayed females were pooled for analyses across ages. The prevalence of age-related progressive impairment was significant in all categories. The percentage of 11- to 12-year-old dogs with impairment in > or = 1 category was 28% (22/80), of which 10% (8/80) had impairment in > or = 2 behavioral categories. Of 15- to 16-year-old dogs, 68% (23/34) had impairment in > or =1 category, of which 35% (12/34) had impairments in > or = 2 categories. There were no significant effects of body weight on the prevalence of signs of dysfunction in the behavioral categories. CONCLUSIONS AND CLINICAL RELEVANCE: Data collected provide estimates of the prevalence of various degrees of age-related behavioral changes associated with cognitive dysfunction in dogs. Age-related behavioral changes may be useful indicators for medical intervention for dogs with signs of cognitive impairment.  相似文献

A survey was carried out in 25 riding centers to evaluate the prevalence of behavioral problems among saddle horses and to investigate the relationship between these and individual traits, training and management of the affected horses. Seven percent of the 650 horses examined had some kind of behavioral problems, and crib-biting was the most frequent. These behavioral problems seemed to be related to the sort of training and management. Show jumping horses tended to be affected simultaneously by more than one behavioral problem and to be more aggressive towards other horses. Although show jumpers were ridden more often, they had fewer opportunities to graze. The prevalence of behavioral problems was lower among those horses ridden Western style than among those ridden English style; the latter employs more hand to bit contact. The study also showed that horses groomed and ridden by one and the same person had more problems than horses groomed and ridden also by different people.  相似文献

In modern intensive husbandry, systems often restrict farm animal behavior. Behavioral needs will be generated by external stimuli such as stressors deriving from environmental factors or the method of animal care, or some internal factor in farm animals. This means that behavioral restriction would induce maladaptation to stressors or chronic stress. Such a risk of behavioral restriction degrades an animal's physical and mental health and leads to economic loss at a farm. Methods to reduce the risk of behavioral restrictions are to ameliorate the source of a stressor through adequate animal management or to carry out environmental enrichment. This review is intended to describe the relation between animal management and behavioral needs from the perspective of animal motivation.  相似文献

Most cats entering shelters are euthanized. This study used behavioral assessments to determine how quickly a cat acclimated to its new environment and whether enrichment eased this transition. Twenty-five cats at 2 municipal shelters were evaluated with 2 separate standardized behavioral assessments at 3 separate times, beginning the day after entering the shelter. One behavioral assessment included an in-cage evaluation, whereas the other assessment involved a stepwise combined in- and out-of-cage evaluation. Eleven of the cats were given a cardboard box to hide in and a toy in the cage, whereas 14 cats were not given these objects. Our results suggest that cats need 72 hours to achieve optimum behavioral scores and a decrease in stress levels based on the 2 separate evaluations. The tests were correlated in their outcomes.  相似文献

The objective of this study were (1) to establish the duration of behavioral estrus signs and timing of ovulation in Murrah buffaloes (n = 10) and (2) to determine relationship between behavioral estrus signs with change in plasma estrogen concentrations. Estrus and its behavioral signs were detected at hourly intervals by visual observations, per recta examination of genitalia and bull parading four times in a day for 30 minutes each. Among the behavioral signs of estrus, swollen vulva (80%) was the best indicator of estrus followed by excitement (70%). Among the duration of behavioral estrus signs the first and longest duration of estrus signs was swollen vulva which was seen upto 19.8 ± 0.8 h after onset of estrus. The mean total duration of estrus symptoms from appearance to disappearance of all the behavioral estrus symptoms was 23.5 ± 1.7 h. All the behavioral estrus symptoms were observed during the period of estrogen surge. Endocrine profile during the periestrus period showed that the mean peak concentrations of total estrogen 23.9 ± 3.9 pg/ml occurred at 8.8 ± 1.7 h after onset of estrus. The average number of estrus symptoms observed per animal during onset of spontaneous estrus was 5.7. Ovulation occurred after 37.4 ± 1.7 h after onset of estrus and 13.4 ± 1.0 h after end of total estrogen surge respectively. In conclusion, our results suggest that all signs of behavioral estrus occurred during the preovulatory rise in estrogens. The first sign of estrus to be observed was a swollen vulva and this symptom persisted the longest.  相似文献

Veterinary behavioral medicine remains an under-supported, under-appreciated, and under-taught specialty within veterinary medicine. Neuropsychopharmacology is the aspect that has provided the field with the most scientific legitimacy, but is also one of the most hotly debated. Paradigms for use of pharmacologic intervention include firstly ruling out any underlying medical cause. If a behavioral diagnosis can be made, treatment with psychotropic medication may be considered, although their use is most effective as part of an integrated treatment program that includes behavior modification. Used without an understanding of the mechanism of action, pharmacologic intervention may only blunt or mask behavior without altering processes or environments that produced the behavior. This paper reviews specific drugs, mechanism of action of those drugs, and relevant uses are reviewed for cats. Future advances in treatment in veterinary behavioral medicine will be pharmacological and neurophysiological. As the field of veterinary behavioral medicine expands, its paradigm will enlarge to include routine combination therapy and the implementation of neuropharmacological intervention as a diagnostic tool.  相似文献

The central nervous systems of eight dogs with behavioral changes were compared. Three had pathological lesions involving the limbic system. The nervous system and, in particular, the limbic system should be examined as a possible site for lesions in dogs with a history of behavioral changes.  相似文献

A 15-month-old female German Shepherd dog showing compulsive tail chasing was treated with a treatment protocol of pharmacological therapy (using clomipramine) in conjunction with behavioral and environmental management. The responses to the treatment protocol were assessed once a week for 7 weeks in respects to behavioral conditions and the frequency of bouts and its duration. The behavior history including mother, father, and her littermates were also evaluated for the apparent diagnosis. The compulsive tail chasing of the patient dog was improved on the aspect of behavioral condition and gradually decreased in the frequency and duration of bouts. However, in the mid of treatment, the animal showed an aggressive behavior as a concurrent sign associated with compulsive tail chasing.  相似文献

This article is not intended as a comprehensive exploration of all issues related to the behavioral management of working dogs or as a survey of all manners of canine employment. Rather, it is one person's perspective into the challenges of managing a behavioral medicine program in a large-scale working dog program environment. The issues presented, however, are those that are commonly encountered when selecting, assessing, diagnosing, and treating working dogs. I hope this article provides insight not only into the author's program but also into some of the unique challenges in working with working dogs as well as some of the commonalities of this kind of behavioral practice with companion animal settings.  相似文献

The objective of this study was (1) to establish the duration of behavioral estrus signs and timing of ovulation in Murrah buffaloes (n = 10) and (2) to determine relationship between behavioral estrus signs with change in plasma estrogen concentrations in animals treated with Heatsynch protocol. Estrus and its behavioral signs were detected at hourly intervals by visual observations per rectal examination of genitalia and bull parading four times in a day for 30 min each. Among the behavioral signs of estrus, swollen vulva was the best indicator of estrus followed by excitement and chasing by bull (90%). Among the duration of behavioral estrus signs, the first and longest duration of estrus signs was swollen vulva, which was seen up to 21.6 ± 1.1 h after onset of estrus. The mean total duration of estrus symptoms from appearance to disappearance of all the behavioral estrus symptoms was 40.2 ± 1.8 h. Endocrine profile during the periestrus period showed that the mean peak concentrations of total estrogen 330.9 ± 108.3 pg/ml occurred at 9.6 ± 1.0 h after estradiol benzoate injection. The average number of estrus symptoms observed per animal during Heatsynch treatment was 7.1. Ovulation occurred after 50.0 ± 2.0 h after estradiol benzoate treatment and 26.7 ± 2.0 h after end of total estrogen surge, respectively. In conclusion, our results suggest that all signs of behavioral estrus occurred after the preovulatory rise in estrogens. The first sign of estrus was swollen vulva, and this symptom persisted the longest.  相似文献

This study examined the difference in dog owning between Japan and the United States, and the effect of these differences on dogs’ behavioral characteristics. Behavioral evaluations of privately-owned dogs were obtained by using online questionnaire. We compared background and demographic information from the two countries and analyzed the effects of these differences on behavioral characteristics in dogs. The results indicated that there was a bias in the dog breeds kept in Japan compared to the United States and that Japanese dogs’ body weight was lower than the US dogs. The main source of dog acquisition was pet stores in Japan and breeders and/or shelters in the United States. Multiple linear regression analysis found that Japanese dogs showed more aggression to household members and higher energy, restlessness and fear of non-social stimuli than US dogs, while US dogs showed more fear of unfamiliar persons, separation-related behavior and excitability. US dogs also showed higher levels of trainability and attachment to owners. The lower dog’s body weight was, the higher the behavioral scores except for trainability were. When dogs that were obtained under 3 months of age were analyzed, the younger the dogs were when their owners obtained them, the higher the scores on some behavioral problem factors were. The higher rates of problem behaviors among Japanese dogs compared with US dogs suggest that the preference for small breed dogs and poor early development environment influenced the behavioral characteristics of dogs.  相似文献

OBJECTIVE: To evaluate a behavioral intake questionnaire in animal shelters for the presence of biased results and assess its use in the characterization of behavioral problems of dogs relinquished to shelters. DESIGN: Cross-sectional study. Animals-54 dogs being relinquished to a shelter and 784 dogs belonging to veterinary clients. Procedure-Owners who were relinquishing their dogs and agreed to complete the behavioral questionnaire were alternately assigned to 1 of 2 groups; participants were aware that information provided would be confidential or nonconfidential (i.e., likely used for adoption purposes). Data from confidential and nonconfidential information groups were compared, and the former were compared with data (collected via the questionnaire) regarding a population of client-owned dogs. RESULTS: Analyses revealed significant differences in 2 areas of reported problem behavior between the confidential and nonconfidential information groups: owner-directed aggression and stranger-directed fear. Compared with client-owned-group data, significantly more relinquished shelter dogs in the confidential information group were reported to have owner-directed aggression, stranger-directed aggression, dog-directed aggression or fear, stranger-directed fear, nonsocial fear, and separation-related behaviors. CONCLUSIONS AND CLINICAL RELEVANCE: Among persons relinquishing dogs to a shelter, those who believed questionnaire responses were confidential reported owner-directed aggression and fear of strangers in their pets more frequently than relinquishers who believed responses were nonconfidential. Confidentiality had no apparent effect on the reporting of other assessed behavioral problems. Results suggest that behavioral questionnaires may sometimes provide inaccurate information in a shelter setting, but the information may still be useful when evaluating behavior of relinquished dogs.  相似文献

Boundaries between behavioral conditions and medical differentials are likely to blur more rather than less as we learn more about genomic, cellular, and subcellular effects on common conditions. These changes should lead to better treatment but may also require a paradigm shift in how we view behavioral conditions and the mechanisms that contribute to them.  相似文献

Aging pets often suffer a decline in cognitive function (eg, memory,learning, perception, awareness) likely associated with age-dependent brain alterations. Clinically, cognitive dysfunction may result in various behavioral signs, including disorientation; forgetting of previously learned behaviors, such as house training; alterations in the manner in which the pet interacts with people or other pets;onset of new fears and anxiety; decreased recognition of people, places, or pets; and other signs of deteriorating memory and learning ability. Many medical problems, including other forms of brain pathologic conditions, can contribute to these signs. The practitioner must first determine the cause of the behavioral signs and then determine an appropriate course of treatment, bearing in mind the constraints of the aging process. A diagnosis of cognitive dysfunction syndrome is made once other medical and behavioral causes are ruled out.  相似文献

“Coping” or “coping strategy”, defined as the behavioral and physiological efforts of animal to master the situation, is more and more in interest of researchers dealing with applied animal behavior and welfare. Knowledge about “coping styles” may be helpful in understanding individual adaptive capacity to stressful events. At least two types of animal coping strategy (or coping style) can be involved: (1) active copers (proactive) and (2) passive copers (reactive). The individual differences in stress response to threatening situations have been found in horses, and these animals can show specific coping strategies such as other species. This article reviews the set of behavioral, psychoneuroendocrine, and psychoneuroimmune mechanisms involved in animal adaptation to environmental challenges and discusses the relationship between behavioral and physiological factors involved in stress response of the horse. Exploring coping strategies in horses and in any captive animal can be successful when a multidimensional approach including behavioral, neural, hormonal, and hematological measures is considered. Knowledge on stress coping styles can provide valuable information to predict the behavior of individuals during response to specific challenging situations. Moreover, assessing individual differences in adaptation strategies can be useful in horse selection to different exploitation tasks and reproduction.  相似文献
