Introduction

The Antimicrobial Stewardship Guidelines in companion animals are designed to aid practicing veterinarians in choosing appropriate antimicrobial therapy to best serve their patients and minimize the development of antimicrobial resistance and other adverse effects. The Guidelines presented below were developed by an expert task force and provide a recommended framework for judicious antimicrobial use in companion animals.

Position Statement

Antimicrobial stewardship, as defined by the American Veterinary Medical Association (AVMA), refers to the actions veterinarians take individually and as a profession to preserve the effectiveness and availability of antimicrobial drugs through conscientious oversight and responsible medical decision-making, while safeguarding

ABSTRACT

The goal of this study was to determine if anxiety, aggression, and fear-related behaviors are more common in pruritic dogs with atopic dermatitis than nonpruritic, healthy dogs. One hundred forty-one pruritic dogs >1 yr of age with a clinical diagnosis of atopic dermatitis and a >3 mo history of pruritus were recruited. Dog owners completed a behavioral survey (canine behavioral assessment and research questionnaire) and a pruritus scale (pruritus visual analog scale). Pruritic, atopic dogs showed significant increases in fear- and anxiety-related behaviors as well as aggression compared with a large control group of healthy dogs. Stranger-directed aggression, owner-directed aggression, familiar-dog aggression, dog-directed fear, nonsocial fear, touch sensitivity, excitability, and attention-seeking behaviors were all increased in the study group. Trainability was decreased in the study group. Chronically pruritic dogs experience fear and anxiety and are more likely to display aggression. This is an important welfare issue for these animals. Early recognition of the behavioral derangements that can be associated with chronic pruritic skin disease could allow early intervention with a multidisciplinary approach for these patients, thus improving patient and owner quality of life and long-term treatment outcomes.

ABSTRACT

Abdominal ultrasound with spleen and liver cytology is part of routine staging for canine mast cell tumors (MCTs). However, such tests are associated with increased morbidity and cost. Therefore, the objectives of this study were to determine if spleen cytology was predictive of liver cytology in canine MCTs and if any patient or tumor variables were associated with spleen and/or liver metastasis. Records of dogs with MCTs and cytology of spleen and liver were reviewed. Two hundred five patients were included. Overall, 22 (10.7%) patients had metastasis, with 21 (10.2%) and 13 (6.3%) having spleen and liver metastasis, respectively, and 12 (5.9%) having both. For patients with a positive (or negative) spleen cytology, the odds ratio of having a positive (or negative) liver cytology was 233.49. However, a negative spleen cytology had a higher predictive value (0.99) than a positive cytology (0.54). Finally, the presence of local and systemic signs and tumor size were associated with spleen, liver, and/or spleen or liver metastasis. These results suggest that spleen cytology is predictive of liver cytology in staging of canine MCTs, and increasing tumor size and presence of local or systemic signs are associated with an increased risk of visceral metastasis.

ABSTRACT

A recessed vulva is a conformational abnormality that predisposes affected dogs to urinary tract infections. An episioplasty can be recommended for correction of this abnormality when medical management of recurrent urinary tract infection fails. The objective of this study was to investigate the type and incidence of urogenital abnormalities visualized by cystoscopy in dogs presenting for episioplasty. Medical records of 29 dogs that presented for an episioplasty and had a concurrent or prior cystoscopy were reviewed. Eleven of the 29 dogs had urogenital abnormalities diagnosed on cystoscopic evaluation, and 1 dog was diagnosed with a urogenital abnormality during vaginal examination while under general anesthesia. Ten of the dogs with urogenital abnormalities had a corrective procedure performed, 8 of which were cystoscopically assisted. Cystoscopy provides the ability to directly visualize the urinary tract and obtain samples for biopsy and culture and facilitates correction of some anatomic abnormalities that may predispose the patient to developing recurrent urinary tract infections. Cystoscopy should be considered as a routine part of a thorough evaluation of the urinary tract in cases presenting for episioplasty.
