Whenever I am ready for a new foster I check out local animal control's petfinder a few times a week. Otherwise, maybe once every few months I'll look at dogs for me. I could add one any time, but don't need to, so I usually resist. I find a lot of dogs' petfinder ads through facebook dog friends and I have applied for one in the last 6 months- I was approved, but didn't make the trip (a few states away) to see him before he got adopted, so I missed out.
