Well, I love rottweilers (the dog). Have always had them in my life. My last two service dogs were rotties, and I also used to compete at performance shows with them.
One fun activity I used to do is "Dog Carting". Something rottweilers used to do back in their native Germany (Pull carts with milk or meat). Here in the US, we set up a course and have various levels of skill in drafting or carting.
At the most skilled level, the trainer-owner actually rides in the cart and uses verbal commands to guide the dog through an intricate obstacle course. (One rottie can easily pull two adults in a well balanced cart or wagon). So my name comes from that.
Everyone knew me as the lady who was out driving her Rotties or teaching others carting classes.

Warmly,
Jackie
