Whoa!

I taught my dogs to 'whoa'. So if we're out walking and I say "whoa" they stop where they are. Well yesterday, I hopped on my horse while he was out in the field and rode him around a little, no saddle no bridle. My dogs were milling about and my horse started trotting off and with no means to steer I said WHOA! Well my dog stopped directly infront of my horse! I quickly shouted at my dog to "GO!" And he scooted out of the way and my horse finally stopped. And that's how I learned my dogs whoa command is better than my horses.
