Pug Rescue
We were very lucky to find Bruno, Cassie, and PeeWee through Pug Rescue.  We try and support Pug Rescue Organizations by attending their fundraisers, volunteering to do home checks, and making donations when we are able.  We even substitute fostered a couple of sweeties for a week (see Molly & Porky on our Friends page!), though it was a challenge having five Pugs in the house!  Please check out these links and think of how you can help Pugs in need.
These guys are GREAT!  They're a newer organization, but the people are the old Pug Rescue of Sacramento gang that hooked us up with the Pug Family!  They're VERY dedicated to saving Pugs and Pug Mixes in need!
PROS
Pug Rescue - Bay to the Borders
PROS is the Pug Family's alma mater!  They rescue LOTS of needy Pugs and have great fundraising events!  (Much of our Pug Collection is from PROS raffles, silent auctions, and live auctions!)  Check them out!
Pugs 'N Pals
of Southern California
We've done a home check or two for Pugs 'N Pals!  (Every now and then a San Francisco person will fall in love with a needy Pug in Southern California!)  I hear only good things about these folks, and they have a GREAT website!
