One Angry Muskox

Dr. Oakley stops at a local farm to run some tests on horses that may be at risk for a highly contagious disease, transmitted through the bite of horse flies. Then she pays a visit to the angriest muskox in the Yukon for a routine check-up, but he doesn't plan on surrendering without a fight. Later Dr. Oakley helps a devoted dog owner figure out the best options for his sick yet beloved family lab suffering from a chronic cough caused by a blocked windpipe.
