Stewart, our basset hound, has...

...been favoring his right hind leg lately. So my wife took him in to see the veterinarian the other day. (You know, the sixty-something guy with the jet-black toupee? Very natural-looking.)

Anyway, the good doctor's expert diagnosis was either a torn ACL or just a plain ol' injured knee. (If it's the former, Stew may need surgery.)

Wait a minute; dogs can tear their ACLs? And basset hounds have knees? Who knew?
