I know they mean well. I was walking my springer/lab x this afternoon, stopping every time he pulls and its starting to work.
A total stranger said 'I've got springers, what you need is a willow switch and tap him on the nose every time he pulls'. And kept pushing his back to make him sit - I was so incensed that 'please don't do that' stayed in my head and didn't come out of my mouth. He was trying to help but there is no way I'm going to hurt my pup.
The next stranger said 'don't worry about him jumping up, that's fine, mine does that all the time. Here puppy, puppy!!'
Why do they do it?!
