Since I own 3 horses and ride a bit, I would have to go with Horses, followed by Cats (have one of those right now), followed by dogs (endless friendly and useful critters) and Giraffes (silly looking but very neat) 
I'd rather be a Soldier with a mule and mountain gun, than Knight of old, with spurs of gold, or Roman, Greek or Hun. For when there's trouble brewing, they always send for me!
