Canine mitral valve size as measured by computed tomography.

Objective: To measure the mitral annulus in dogs. Our hypothesis was that mitral measurement would be possible and consistent among observers using CT.

Sample: Thoracic CT scans of dogs without known heart disease.

Long-Term Assessment of Bone Regeneration in Nonunion Fractures Treated with Compression-Resistant Matrix and Recombinant Human Bone Morphogenetic Protein-2 in Dogs.

Objective:  The aim of this study was to assess bone density, bone architecture and clinical function of canine nonunion distal appendicular long bone fractures with a defect treated with fixation, compression-resistant matrix and recombinant human bone morphogenetic protein-2 (rhBMP-2).

Study Design:  Prospective cohort study with dogs at least 1-year post treatment. Computed tomography was performed and quantitative measurements from previous fracture sites were compared with measurements from contralateral limbs.

Carpal Extension Angles in Agility Dogs Exiting the A-Frame and Hurdle Jumps.

Objectives:  The aim of this study was to determine the mean carpal extension angles in dogs participating in the A-frame and hurdle jumps, and to determine if the use of a carpal brace changed the carpal extension angle.

Study Design:  Data from 13 healthy agility dogs were included. Approximately 1 cm square adhesive tape markers placed on both forelimbs served as anatomic landmarks for carpal angle measurement.
