Hi & Welcome to the Board Mr. Graham. I spent the 19 so minutes absolutely amazed at your "Walking Baseball" exercise. Totally new to the World of Labradors or any Retriever breed, so I've never experienced field work between a handler and his partner. Your explanations on are really easy to understand. The terminology, well, all new but I have gotten a gist of what they mean through listening and viewing your retrievers.
Thank you so much for sharing this. Know a Lab is a "thinking" kind of dog, enjoying companionship and a challenge. Really enjoy watching you and your dogs work together.
