while Gus is still young there are so many opportunities to work with him. I have not bothered with sit and stay commands rather I ask him certain things like in the first video while he is playing with Bro I call him to me.
As I have said before the most important thing is not the words I use but how I say those words. Imagine trying to explain something to someone who doesn’t speak the same language as you. If you expect them to understand you you could become frustrated and if this reflects in your voice it will make things harder. We don’t have to speak the same language as another person too know if they are polite, calm nervous, agitated or angry. When communicating there are three stages, actions, reactions and interactions and at any of these stages if anger is shown it makes training so much harder. Keep calm and use your tone of voice right for the right situation if the dog is not doing what you want I would say AHH in a deep tone and over time Gus will learn that AHH means he is doing something wrong.
When he is doing what I want I would be talking to him in a nice calm tone of voice, so when I call him up to me in a calm tone I would give him a pat then let him carry on with what ever he was doing. Repeating this enough times will have him coming anytime I call him.
