I have the feeling that this is my dog!
He disappeared 2 months ago. I don't want to get my hopes up but I just emailed her and left a voicemail on her phone. My dog is a corgi, is brownish reddish and did have a blue collar on. I put an ad on craigslist 2 months ago and someone who saw that ad emailed me about this post, which is on Petfinder.com.
