Hi swissmiss24 I would have been glad to help out but sadly I am out of town at exactly that time. Hope you find someone nice but if not and you are stuck, I'd really recommend the tierheim at Rümlang. I think its the nicest one we've seen, the animals (ALL kinds!) have lots of space, its green and well looked after, the pooches are walked by volunteers and I think you get a fair deal price wise.
Good luck!
