Might be a stupid question. But I noticed today with sadie when I was outside,if I used a more firm and loud,not yelling but louder than you would talk to someone,that she responded more quickly and better than usual. I always use a firm voice when training her and when telling her commands through out the day but never at a higher volume. Good or bad thing? I guess I dont want her to feel like she's in trouble and I'm yelling at her. Do dogs take volume into consideration or is more about the tone of your voice? I think she needs a firmer hand when training so maybe I should be using a louder,more firm voice for commands?
