I'm 19 years old (turning 20 in June). I have been doing dog walking/walks from when I was 11 and could go out and walk dogs :). I've walked dogs for friends and family as-well as people I've never met and even with aggressive/shy or anxious dogs I do really well to keep them calm and stay away from what triggers them. Dogs to me are like people like me and you and the energy you give off to a dog will effect the way they act or behave! I like to keep calm in situations where the dogs might not be the most comfortable E.g. meeting/seeing dogs or seeing other animals/vehicles or even people. No dog is a bad dog maybe unless they do a 1 or 2 on the carpet but overall all big dogs or small, fat or slim, anxious or confident I love all dogs :) I have had anxious dogs not be anxious and also dogs which react to certain things not because you have to keep calm and give them good energy:)
