I could look into it - I'm not sure if there are any hound clubs where we are.
And yes, that situation is frightening! I wanted to communicate my desire to train a recall for safety as well as obedience/fun. We live in a city at a major intersection - which is why I got my dog a harness - and why we'd never let her off-leash in the city. But I was hoping that we could work towards leash-free time when we go on our weekend day-hikes/runs.
News from those rescue hounds you mentioned doesn't sound promising...
I'm not giving up yet though!
