How wonderful that you are looking to adopt a dog in need - good on ya!
Here is the Swiss-wide database of homeless animals:
http://www.tierdatenbank.ch/cms/tier...unschtier.html
You can search by various critieria, including age, canton, sex, and other traits.
Don't be too put off by distance - a few hours' travel isn't much when you consider the next 10 or 15 years of loving, loyal companionship.
Browse through the database, keeping an open mind - hopefully you'll see a little one who tugs at your heart strings. For the contact information for each animal click on 'Anbieter Information'.
Best of luck in your search - hopefully your next best friend is out there, waiting for you.
