I haven't gotten tangled with the ropes yet, but I'm sure that won't last too long. Lol My horse is the one in my avatar. He's going to be 4 in April. He's a Qh gelding. Anyway, yes he has been around cows. He's pastured with 5 head right now. He loves them! Every time we ride in the pasture he loves to follow after them. He heads straight for them. I have yet to run one on him, but I doubt that will be a problem. His lines include Peppy San, Doc Bar, Leo, Poco Tivio, Joe Reed II, Three Bars, the list goes on. Lots of cow in him.
You're right, its not that fun when you're starting out! :(
