Which command is often used to keep a dog focused during training?

The command that emphasizes keeping a dog focused during training is specifically the use of "Watch" or "Focus." This command is designed to encourage the dog to maintain eye contact with the handler, which greatly enhances concentration and engagement. By prompting the dog to focus on the handler, it helps to minimize distractions from the environment, thereby improving the overall effectiveness of the training session.

This command is particularly useful in situations where distractions may arise, allowing the handler to better communicate and reinforce commands. The ability to direct a dog's attention fosters a strong bond between the dog and handler, which is essential in effective training.

Other commands, while useful in their own contexts, do not specifically aim to enhance focus in the same manner. "Come" or "Sit" typically communicate actions rather than concentration, "Heel" or "Stay" instruct the dog on positioning relative to the handler, and "Drop it" or "Leave it" are commands that manage behaviors related to objects rather than maintaining focus. Thus, "Watch" or "Focus" stands out as the most directly related to training a dog's attention and concentration.
