Epidemiological Associations Between Brachycephaly And Upper Respiratory Tract Disorders In Dogs Attending Veterinary Practices In England, Dan G. O'Neill, Caitlin Jackson, Jonathan H. Guy, David B. Church, Paul D. Mcgreevy, Peter Thomson, Dave C. Brodbelt

Epidemiology Collection

Background: Brachycephalic dog breeds are increasingly common. Canine brachycephaly has been associated with upper respiratory tract (URT) disorders but reliable prevalence data remain lacking. Using primary-care veterinary clinical data, this study aimed to report the prevalence and breed-type risk factors for URT disorders in dogs. Results: The sampling frame included 170,812 dogs attending 96 primary-care veterinary clinics participating within the VetCompass Programme. Two hundred dogs were randomly selected from each of three extreme brachycephalic breed types (Bulldog, French Bulldog and Pug) and three common small-to medium sized breed types (moderate brachycephalic: Yorkshire Terrier and non-brachycephalic: Border Terrier and West Highland …

Prevalence Of Disorders Recorded In Cavalier King Charles Spaniels Attending Primary-Care Veterinary Practices In England, Jennifer F. Summers, Dan G. O'Neill, David B. Church, Peter C. Thomson, Paul D. Mcgreevy, David C. Brodbelt

Epidemiology Collection

Background: Concerns have been raised over breed-related health issues in purebred dogs, but reliable prevalence estimates for disorders within specific breeds are sparse. Electronically stored patient health records from primary-care practice are emerging as a useful source of epidemiological data in companion animals. This study used large volumes of health data from UK primary-care practices participating in the VetCompass animal health surveillance project to evaluate in detail the disorders diagnosed in a random selection of over 50% of dogs recorded as Cavalier King Charles Spaniels (CKCSs). Confirmation of breed using available microchip and Kennel Club (KC) registration data was attempted. …

Prevalence Of And Risk Factors For Degenerative Mitral Valve Disease In Dogs Attending Primary‐Care Veterinary Practices In England, M. Mattin, A. Boswood, D. B. Church, J. López-Alvarez, P. D. Mcgreevy, D. G. O'Neill, P. C. Thomson, D. C. Brodbelt

Epidemiology Collection

Background

To date, epidemiological studies on degenerative mitral valve disease (DMVD) in dogs have largely reported referral caseloads or been limited to predisposed breeds. Analysis of primary‐care data to identify factors associated with DMVD would help clinicians identify high‐risk individuals and improve understanding.

Objectives

To estimate the prevalence of and identify risk factors for DMVD in dogs attending primary‐care veterinary practices in England.

Animals

Cases were identified within the electronic patient records of 111,967 dogs attending 93 practices. Four hundred and 5 dogs were diagnosed with DMVD (diagnosed cases) and a further 3,557 dogs had a heart murmur (HM) consistent …

Prevalence And Risk Factors For Mast Cell Tumours In Dogs In England, Stephanie J.W. Shoop, Stephanie Marlow, David B. Church, Kate English, Paul D. Mcgreevy, Anneliese J. Stell, Peter C. Thomson, Dan G. O'Neill, David C. Brodbelt

Epidemiology Collection

Background

Mast cell tumour (MCT) appears to be a frequent tumour type in dogs, though there is little published in relation to its frequency in dogs in the UK. The current study aimed to investigate prevalence and risk factors for MCTs in dogs attending English primary-care veterinary practices.

Methods

Electronic patient records from practices participating in the VetCompass animal surveillance project between July 2007 and June 2013 were searched for MCT diagnosis. Various search terms and standard diagnostic terms (VeNom codes) identified records containing MCT diagnoses, which were evaluated against clinical criteria for inclusion to the study. MCT prevalence for …
