so where do I go to get my dog started in weight pull? He is only 10 or 11 months, but I think he would love it. We are in the Rochester area, east side. He runs with me at my running club every Tuesday night, its hills and about 4 miles. We also run 5 on Saturdays, so he is in good shape. Don't want to have a get a harness though if he is not into it, he is about 45lbs, can you borrow these things?
