After a week, I got absolutely ZERO inquiries about my dog via PetFinder. From my experience, this site must be a ghost town! I consistently got the most responses from CraigsList (I eventually found an adopter via CL). In second place was NextDoor. I understand that it can be nearly impossible to give away a dog, and you want to advertise everywhere you can. But, to start, I would save your $10, and just try NextDoor and CraigsList and renew your ad every 5 days or so. Hopefully, CL doesn't ban you from reposting too often. You might have to replace all of your photos, rewrite the wording of your listing, use a new email, and new phone number (or none) in order to get your listing back on CraigsList if they ban you.
