Body weight at 10 years of age and change in body composition between 8 and 10 years of age were related to survival in a longitudinal study of 39 Labrador retriever dogs.

Background: Overweight and obesity have been adversely associated with longevity in dogs but there is scarce knowledge on the relation between body composition and lifespan. We aimed to investigate the effects of body composition, and within-dog changes over time, on survival in adult Labradors using a prospective cohort study design. The dogs had a median age of 6.

Exceptional longevity and potential determinants of successful ageing in a cohort of 39 Labrador retrievers: results of a prospective longitudinal study.

Background: The aim of this study was to describe the longevity and causes of mortality in 39 (12 males, 27 females) pedigree adult neutered Labrador retrievers with a median age of 6.5 years at the start of the study and kept under similar housing and management conditions. Body condition score was maintained between two and four on a 5-point scale by varying food allowances quarterly.

Computed tomographic documentation of the natural progression of humeral intracondylar fissure in a cocker spaniel.

Objective: To report the computed tomographic (CT) documentation of humeral intracondylar fissure (HIF) developing after complete ossification of the humeral condyle (HC).

Study Design: Clinical report.

Animals: Male 3 year old working (English) Cocker Spaniel.

Maxillomandibular circular external skeletal fixation for repair of bilateral fractures of the caudal aspect of the mandible in a dog.

Objective: To describe the novel use of circular external skeletal fixation (CESF) for repair of bilateral fractures of the caudal aspect of the mandibles.

Study Design: Clinical report.

Animals: A 5-month-old female Newfoundland.

The effect of weight loss on lameness in obese dogs with osteoarthritis.

This paper describes the effect of weight loss on lameness in obese dogs with osteoarthritis (OA). Fourteen obese client-owned dogs with clinical and radiographic signs of OA participated in an open prospective clinical trial. After a screening visit and a visit for collection of baseline data, the dogs were fed a restricted-calorie diet over a study period of 16 weeks that incorporated six follow-up visits.

Ex vivo evaluation of the effect of tibial plateau osteotomy on the proximal tibial soft tissue envelope with and without the use of protective gauze sponges.

Objective: To investigate the effect of tibial plateau leveling osteotomy (TPLO) on the proximal tibial soft tissue envelope with and without use of protective gauze sponges, and to determine whether the action of an oscillating saw blade on the gauze sponges would result in retention of particulate cotton debris.

Study Design: Cadaveric study.

Animals: Medium to large breed dog cadavers (n=10; 20 pelvic limbs).

In vitro validation of a technique for assessment of canine and feline elbow joint collateral ligament integrity and description of a new method for collateral ligament prosthetic replacement.

Objective: To assess the ability of an operator to differentiate intact from transected canine and feline elbow joint collateral ligaments (CL) using a reported manipulative test (Campbell's test) and to determine the potential for elbow joint luxation in canine and feline elbows with intact, transected, and surgically stabilized CL.

Study Design: In vitro biomechanical study.

Sample Population: Canine (n=6) and feline cadavers (n=3).

Contour and volume assessment of repairing mandibular osteoperiosteal continuity defects in sheep using recombinant human osteogenic protein 1.

Background: This study describes the contour and volume of reconstructed mandibles using recombinant human osteogenic protein 1.

Material And Methods: The investigation was conducted on six adult sheep, where a unilateral 35 mm parasymphyseal osteoperiosteal continuity defect of the mandible was created. Recombinant human osteogenic protein 1 and type-I collagen (as carrier) were applied to the defects.

A minimally invasive novel design for a vascular-pedicled bone segment for experimental studies of reconstruction of mandibular defects.

We describe a new minimally invasive vascularised bone segment (VBS) for experimental reconstruction of the mandible. The study was validated and the feasibility was tested on fresh sheep cadavers. The integrity of the arterial blood supply was confirmed using inferior dental artery static arteriography.

Type I immune-mediated polyarthritis in dogs: 39 cases (1997-2002).

Objective: To determine clinical signs, laboratory findings, relationship to vaccination, and response to treatment for type I immune-mediated polyarthritis (IMPA) in dogs.

Design: Retrospective study.

Animals: 39 dogs

Procedure: Clinical records and radiographic reports from 3 university referral hospitals were reviewed.
