Hi there, love this site. I just came apon this site looking for information on training. My husband and I have 2 Chesapeake Bay Retrievers, 1 Golden Retriever and we just adopted a Border Collie rescue that is 5 months old. We live on a hobby farm in Manitoba, Canada. Our male Chessie competes in Agility and plan on working with the Golden and BC in agility. The BC is so different from the others, I thought the energy level of the Chessie was high but the BC is now top of the list for energy.
