You can always take a step back, but you can never un-teach the bad picture created by a frustrated Trainer. If you can’t keep your energy clean and neutral, close the book and try again tomorrow. The dog will thank you for it. Block out the external noise. Your dog doesn’t care about your goals, your timelines, or what anyone else is doing. They only care about the clarity of the picture right in front of them in this exact repetition.
