OBJECTIVE To determine whether age, breed, sex, weight, or distraction index (DI) was associated with the risk that dogs of 4 common breeds (German Shepherd Dog, Golden Retriever, Labrador Retriever, Rottweiler) would have radiographic evidence of degenerative joint disease (DJD) associated with hip dysplasia. DESIGN Cross-sectional prevalence study. (More)
As the benefits of minimally invasive surgery are more widely recognized by veterinarians and their clients, laparoscopic sterilization of female dogs is growing in popularity. Laparoscopic ovariohysterectomy and ovariectomy procedures in dogs are associated with less postoperative pain and a faster return to normal activity versus open sterilization(More)
OBJECTIVES To describe a technique for, and outcome after, laparoscopic cholecystectomy (LC) for management of uncomplicated gall bladder mucocele (GBM) in dogs. STUDY DESIGN Case series. ANIMALS Dogs (n=6) with uncomplicated GBM. METHODS Dogs with ultrasonographic evidence of GBM but without imaging or laboratory signs of gall bladder rupture,(More)
Magnetic resonance imaging (MRI) was used to examine the lumbosacral spine of 27 dogs with degenerative lumbosacral stenosis. Four normal dogs were also similarly imaged. Compression of the soft-tissue structures within the vertebral canal at the lumbosacral space was assessed in two ways: by measuring dorsoventral diameter on T1-weighted sagittal images(More)
Extrahepatic biliary obstruction (EHBO) was confirmed at surgery or necropsy in 22 cats. Biliary or pancreatic adenocarcinoma was diagnosed by histopathology in six cats and one cat had an undiagnosed mass in the common bile duct. The remaining 15 cats had at least one of a complex of inflammatory diseases including pancreatitis, cholangiohepatitis,(More)

OBJECTIVE To determine prevalence of a radiographic caudolateral curvilinear osteophyte (CCO) on the femoral neck in various breeds and age groups of dogs and to evaluate its contemporaneous relationship with degenerative joint disease (DJD) and distraction index (DI). DESIGN Cross-sectional prevalence study. ANIMALS 25,968 dogs, including 3,729 German(More)
OBJECTIVE To describe a surgical technique for laparoscopic medial iliac lymph node (MILN) extirpation, and to describe the quality of biopsy specimens obtained. DESIGN Experimental study. ANIMALS Purpose-bred male hound-mix research dogs (n = 8). METHODS Dogs were randomized to groups of left or right-sided laparoscopic surgical approaches. Three(More)
