I have a Staffy doing agility, I have only met one other but am told that there are a few out there doing it. I got my girl when she was 9 months old and whenever we were out walking she would jump up onto any raised surface, you name it, garden beds, gutters, business fences, peoples brick fences and walk along them! Then she started sitting on top of her kennel at home instead of going in it (yes it was a pitch roof). That was when i decided to look into agility. So we found a school so every Sunday i made the trip - over 100km each way!! Havent been going as regularly lately, as i found she needed more focus on me so we have been working intensly on that and it really paid off at her last trial!! She finished 4 out of the 5 rounds she went in. Still working on getting a pass but it will come. Agility is the best thing i have ever come across!
