Have you ever wanted to talk with your dog? Technology that actually enables translation is a little ways off, but in the meantime, hand signals can be a tool within reach!
Training with hand signals can be a great training tool for you and your dog. It's easy to learn and understand; the trick is consistency.
Of course, you will want to decide which signals you'd like to use while training, but once you've decided, just stick with those signals throughout the entire process.
