Comparison of two minimally invasive approaches to the thoracolumbar spinal canal in dogs.

Objective: To describe 2 minimally invasive approaches to the spinal canal for treatment of intervertebral disc disease and compare their efficacy to conventional hemilaminectomy.

Study Design: Experimental; randomized, controlled design.

Animals: Canine cadavers (n = 10; 5 small and 5 large dogs).

Duration of clinical signs prior to total hip replacement in dogs.

Objective: To compare the duration of clinical signs in dogs prior to total hip replacement (THR) for 2 time periods and to determine whether a previous THR influenced the duration of clinical signs prior to THR of the contralateral hip joint.

Design: Retrospective cohort study.

Animals: 833 dogs that underwent unilateral THR (334 dogs between 1992 and 2000 [group 1] and 499 dogs between 2001 and 2009 [group 2]; part 1) and 272 dogs that underwent staged bilateral THR between 1992 and 2009 (part 2).

Effects of diazepam or lidocaine premedication on propofol induction and cardiovascular parameters in dogs.

The effects of diazepam or lidocaine on the propofol induction dose and certain cardiovascular parameters were documented in this randomized, blinded study. Dogs received 0.9% saline (0.
