Hi Zug bound, I too would love to own a hound, but due to work hours, it's just not possible, so to get my "mut" fix I go down to the local dog shelter in Kloten where they willingly let you take their dogs out for walks. I know it's a bit far for you but here's the link incase you're tempted:

You need to present your permit as ID, but they provide the lead (and dog!!) and you're welcome to take along any little treats. Various models of dog in varying sizes available too to suit the walker

Good luck!
