Update on black dog with blue collar

We're fostering the little female dog found last week. We've named her "Sadie" and she's a real sweetheart! She did not have any tags or a microchip, and the vet says she's about 1 1/2 - 2 years old. She's negative for heartworms and is being treated for parasites. She black with tan markings and weighs 32 pounds, but is about 5 pounds underweight.
Sadie's still a little skittish, but very friendly. She gets along with our dogs, and loves to chase squirrels in the back yeard. Please call Petwatch if you recognize her, or would be interested in fostering her. Let us know of anyone who might be interested in adopting her, in case we're unable to locate her owners.
