It looks like you've gotten some great recommendations already, but I just had to chime in.

This clinic is in Everett, but they are wonderful:

Diamond Veterinary Associates
3625 Rucker Avenue
Everett, WA 98201

phone: (425)252.1106

Ruby as well as my RB dog and cat have all gone there (Dr. Susan Zakos is/was their vet). She's simply wonderful, such a kind woman who really loves animals. We became very close with her when Muffy, my RB schnauzer was battling cancer. She helped her (and my family as well) through a lot.
