I answered to you in the gallery thing but i might as well write here too
So my horses are American standardbreds, Windy is a pure yankee, and Willy is 3/4 american, 1/8 french and 1/8 russian.
We don't measure in hands or feet or any other bodyparts, since we have the metric system

Windy is small, only 146cm, and Willy is already bigger than his father. I hope he doesn't get much over 160cm, cuz I like small horses better
In the baby-picture Willy was only 1-month-old, he's born 1st of June, 2004.
Yes, you can start training your horse to pull a cart when he's 1-year-old. Two year olds are racing already. Willy can't get a license though, but it's too complicated to explain why in english

Because runners are trained in a very young age, they are also easier to handle and to train "under saddle" when they are older. They've already gotten used to working.
I think all horses should be trained to pull carts, I don't like most riding horses cuz they are more stubborn and get spooked too easily
Cute-Sega can be vicious cuz she's an aussie and all american breeds are insane

. She's nice to people (she doesn't like children though, but it doesn't bother me cuz i hate children too

), but she can defend herself quite well from intrusive males or otherwise annoying dogs. She's especially strict about other dogs approaching my car
Sega is a working dog, we train obedience and tracking. I only take her to dog shows cuz her breeder wants me to, and because of reasons that again are too complicated for me to explain in english
I haven't tried agility, because it's very stressful for the dog, and because I haven't had Sega's hips/knees/elbows x-rayed yet. Also, memberships to agility clubs are insanely expensive.
And about the horses biting, I meant that kind of serious bite that breaks you arm, not just your fingers
