Abstract

OBJECTIVE:To describe the clinical and epidemiologic features of persons with dog and cat bite injuries who presented to emergency departments.

SAMPLE:Records of 648,492 dog and cat bite-related emergency department visits in California from 2005 to 2019.

PROCEDURES:Visits were selected by standardized International Classification of Diseases, Ninth or Tenth Revision, Clinical Modification codes that indicated a bite as an external cause of injury in the medical record. Incidence rates were calculated for patient demographics, location and month of bite incident, characteristics of bite injury, infection, patient outcome/disposition, and expected source of payment. Cross-sectional descriptive analysis was performed.

RESULTS:The average annual incidence of dog bites was highest in children aged < 10 years and males, while that of cat bites was highest in adults aged ≥ 80 years and females. Bites were more likely to occur in rural settings, in private residences, and during the summer. The median household income for zip codes in which animal bite patients resided was lower than the statewide median household income. Both dog and cat bite injuries were more likely to occur to upper limbs. Bacteria were isolated from 3% of dog bite injuries and 21.5% of cat bite injuries at initial presentation.

CLINICAL RELEVANCE:Epidemiologic findings about persons presenting to emergency departments for animal bite injuries can inform bite prevention efforts by identifying at-risk populations. Effective animal bite prevention demands an ongoing multisectoral program of veterinarians and other health professionals, collaborating with community and governmental organizations, to develop and implement integrated strategies within the context of other socially contributory factors.

Development of a dog owner caregiving style scale (Lincoln Owner Caregiving Questionnaire, LOCQ) and its relationship with behaviour problems in dogs
Compared to owners of dogs without behaviour problems, owners with high scores for the Disorganised caregiving style predicted dogs with separation related problems or with more than one behaviour problem, owners with high Avoidant caregiving style scores predicted dogs with Fear, and owners with high scores for both Disorganised and Avoidant caregiving styles predicted dogs with Aggressivity problems.

Effective treatment with afoxolaner (NexGard) of Trixacarus caviae in a pet guinea pig.
The animal was treated with a single oral dose of 2.50 mg/kg afoxolaner, and the lesions, presence/absence of mites, and intensity of pruritus were evaluated periodically until 2 months post-treatment. A week after the medication, the lesions were milder, but pruritus was still present and was attributed to the healing process. Further examinations showed significant improvement with the complete remission of clinical signs and no mites at the microscopic examination after 4 weeks.

Investigation of maternal mortality and stillbirth in feline dystocia after emergency obstetric care interventions: a retrospective analysis.
Medical treatment was successful in 17% of patients, and 83% underwent surgical treatment for dystocia. Ovariohysterectomy (59%) was the most common surgical method, followed by conservative caesarean section (35%).

Investigating the relationship between canine training classes and post-adoption return rates in North American shelters
Of all the returned dogs, those who attended training were more likely to be returned for owner-related reasons (58.8?%), whereas dogs who did not attend training were more likely to be returned for animal-related reasons (78.9?%). While attending training classes at animal shelters may help to reduce behavioral returns, as shown by the shift in return reasons, they do not appear to reduce return rates significantly for the general shelter population.

Risk Factors for Injury in Border Collies Competing in Agility Competitions.
The jump height relative to the shoulder height was associated with injury, with dogs jumping noticeably above or below shoulder height more likely to report a history of injury. Other identified risk factors included the number of weekends spent competing/year, the number of competitions at the national level, the age when starting elbow height jumps and backside jumps, the acquisition of the dog from a breeder, and the age of the handler.
