If you suffer from agoraphobia and panic attack and anxiety I would have thought that having your dog on a long line would VASTLY decrease these feelings as you would not have to be anxious about what your dog does?
When you are anxious I find people tend to be MORE careful rather than less.
It is just logic.
If you have a dog totally under control then you never have to worry about him getting lost, getting run over etc.
When you ask for an opinion, be sure that you really want one.
You should be proud that you are asking questions, many people go through life never challenging themselves or others.
It is natural to feel a bit despondent at times when you think you were doing well only to be told that what OTHERS see is an entirely different picture.
That is life I am afraid.
There are plenty of things in life you CAN control, doing so will increase your confidence and eventually improve your abilities to cope..
