I've been posting updates of his progress on his profile page on the shelter's website, occasionally posting pictures and vdieos on the FB page, and taking him to one or two adoption events a month. Duncan is really doing great now other than possibly becoming too attached to me and has gone from a shy mess of a dog to a somewhat outgoing happy boy. He actually jumped up to say hi to a stranger on a walk the other week, while not a good behavior in itself he's losing a lot of his shyness around new people for sure.
Honestly right now I'm split between trying flyers as you suggested, asking the rescue to find another foster for Duncan who might want to keep him forever, take a few weeks of Jubel focused time then get a new foster who needs help (possibly with a different rescue that is mostly foster based). I know someone who fosters for the other rescue I'm thinking about and she hasn't had any dog for more than 8 weeks before its adopted. Most important to me is that Duncan doesn't end up back at the shelter as I think he'll regress there but he'd be fine in another home.
