Hi All; Skye, my 5 year old Sheltie and I are glad to join you. When Skye gets barky, I just remember reading the historical uses and origins of Shelties. They were raised to bark - to enable the farmer to find the location of the flocks. They are just doing what comes natural to them. Skye will stop barking when asked 'who is barking?' Any other thoughts from you all? Nan and Skye
