We all get frustrated now and then, but what many don't realize is...so do our dogs.
Yes, dogs get frustrated too. No, they can't come right out and tell you, you have to know how to read their body language and figure it out.
I had a client tell me this morning, she's frustrated her dog isn't getting the homework given. She cried about it and that added insult to injury to the dog not wanting to comply.
I tell clients, all the time, if you are feeling frustrated, STOP the task at hand and come back to it later. Your dog can read your emotions, more than you think, and will feed off said energy.
Give yourself a time out. Take a couple deep breaths. Have a glass of water or whatever to relax. Once you're relaxed and calm, go back to working with your dog. You'll both me happier in the long road!
