Can this help my dog?
Personally, I think that the walking is POTENTIALLY helpful to every dog's well-being.
There is no guarantee that walking will help every dog become more behaviorally stable, satisfied, and rested.
However, it has helped many dogs with a variety of issues including: reactivity, frustration, separation anxiety, hyperactivity, socialization, weight issues, nervous scratching, etc.
If other solutions have not worked for you in the past, whatever your difficulty, why not give it a try?
Walking's success, is partly dependent on an owner's openness to new ideas and ways of doing things and a willingness to put those ideas into practice when the walker is not present.
Are you elderly? Disabled? Work long hours away from home? Have a busy lifestyle? If so, a dog walker is likely to be helpful to you and your dog.
