OBJECTIVE To determine clinical features and outcome in dogs and cats with obsessive-compulsive disorder (OCD). DESIGN Retrospective study. ANIMALS 103 dogs and 23 cats. PROCEDURES Records of patients with OCD were analyzed for clinical features, medication used, extent of behavior modification, and outcome. RESULTS Most dogs affected with OCD had(More)
We examined correlates (sex, size, age) of variation in maximal burst speed (racetrack) and in stamina (time until exhaustion at 0.5 km . h-1) in twopopulations of the iguanid lizard Sceloporus merriami in Big Bend National Park, Texas. Because these populations were known demographically and were studied in several years, we were able to examine the(More)
1. The classic animal models for human psychiatric conditions involves rodents. As prey species, their normal behaviors of avoidance would be considered pathological in humans and dogs. Hence, such models may not be homologous for similar behaviors found in psychiatric pathology in humans. 2. Dogs exhibit pathological behavioral conditions that may be(More)
Behavioral wellness has become a recent focus for the care of laboratory animals, farm and zoo animals, and pets. Behavioral enrichment issues for these groups are more similar than dissimilar, and each group can learn from the other. The emphasis on overall enhancement for laboratory dogs and cats in this review includes an emphasis on behavioral(More)
Rationale: There exists a wide range of animal models and measures designed to assess anxiety or fearfulness. However, the relationship between these models and clinical anxiety symptoms and syndromes is unclear. The National Institute of Mental Health convened a workshop to discuss the relationship between existing behavioral models of anxiety and the(More)
Most of the future advances in therapy with behavioral medicine probably will be pharmacologic. Newer developments in tricyclic antidepressants, specific and nonspecific anxiolytics, narcotic agonist-antagonists, and benzodiazepines will have great relevance for veterinary medicine. As the field of behavioral medicine expands, its paradigm hopefully will(More)
OBJECTIVE To determine the frequency of nonspecific clinical signs in dogs with separation anxiety, thunderstorm phobia, noise phobia, or any combination of these conditions and determine whether these conditions are associated in dogs. DESIGN Case series. ANIMALS 141 dogs. PROCEDURE Diagnoses were established using specific criteria. Owners of dogs(More)
Neurobehavioral deficits in higher cortical systems have not been described previously in a large animal model of diffuse brain injury. Anesthetized 3-5 day old piglets were subjected to either mild (142 rad/s) or moderate (188 rad/s) rapid non-impact axial rotations of the head. Multiple domains of cortical function were evaluated 5 times during the 12 day(More)
