For about 6 weeks after Cassy's brother Sassy died, we went walkees on a leash around the complex. It did seem to help him come to grips with the upset of the time...

Since Livvy came to live with us, he doesn't like the leash anymore, and I haven't tried with Livvy.

When we would go out, I got a lot of weird looks from the neighbors (and one who insists Cass is a dog as cats don't walk on leashes. ) -- our walking consisted of quick sprints between bushes and up staircases and long periods where it appeared I'd tethered myself to shrubs and bushes. (Either trying to untangle the leash, or Cassy refreshed himself in the leaves with a quick nap.) It wasn't the highlight of our bonding experience.

The only loose dogs here belong to a friend who would walk the dogs on alternate paths when we were having our 'walkies'.
