We don't have Schnauzers to rehome ourselves, we put people who have one to rehome in touch with those offering a new home. Hopefully somebody in your area will contact you if they are looking for a new home for their Schnauzer. You could also try Schnauzer Houzer on Facebook, who do a great job of rehoming Schnauzers of all sizes and are always looking for potential adopters. Good luck!
PS Add a comment with your email address so people can contact you if they have a Schnauzer to rehome.
The co-ordinator for Northern Schnauzer Rescue is Pamela Ciceri (based in North Yorkshire)
Pamela.ciceri@btinternet.com They also help to rehome Schnauzers.
Good luck
