Unfortunately where I live no beautiful trails or parks, so I have to 'make do' with what's available. I find just walking with my dogs calms me down if I've had one of those days, but I do take the route which has the least amount of dogs attempting to jump the fence etc. as this isn't conducive to a good walk for either of us.
I do a lot of what you have written in your blog, tricks, allow them to be dogs etc. and try to wear appropriate clothing.
At present we are walking after dark, as it's so hot the sidewalks would burn little paws and I'd be dead from sunstroke, so that adds a new dimension to our walks, because there's all those new shadows around.
I don't play music here, simply because at some point of time during our walk we always are on a very busy road, so traffic noise is something I have to take into account. Once I move to a more salubrious place, music will once more be 'on the menu'.
We also, if there aren't any kids around (parents complain) try out the few kids swings etc. Ra Kismet loves that but Zeus isn't interested in all that agility stuff!
