Hello everyone, I am new to this forum and excited to participate! I am a certified dog trainer using primarily positive reinforcement...love my work! I am looking for advice on teaching a dog to respect the boundries of his/her property when fences are not an option. I will be doing some private training out at the lake this summer and do not have experience in this area, but suspect there will be clients who would like advice on this issue. The cottages run alongside each other along the lake, usually only separated by trees. Many cottagers have dogs they would like to reliably train to stay within the boundries of their lots...any advice or suggestions for addressing this?
