I am not ashamed to be a zoo and do this quite frequently. First off, I have paw tattoos and have been asked stuff like "does this means what I think it means?" more than once. These tattoos are always good conversation starters, especially at fetish parties and erotic events, where it is already clear that the audience is sexually more open.
Since my husband and I are also swingers, we do meet a lot of people for sex. I almost always try to test the waters with them by making comments which can be picked up by fellow zoos or by people interested in the topic. We mostly joke around, in the sense of "...ahh, this old lady needs to get herself a dog..." etc. You immediately see how people react. Either they don't react and avoid the subject, or they roll their eyes, etc. In those cases, you just let it go and change the subject "Just kidding, LOL", and move on. Some folks, however, do show a positive reaction, which quite often leads to things like "I'd love to try but our dog is neutered..." or "I let my dog lick as a teen".
Over the years, we have met at least a dozen people that way, both couples and also single women, whom we could successfully introduce into dog fucking. This was all through conversations, not online forums. Zoophilia is more common than one would think, at least the urge to try is. Or you wouldn't have a shit ton of zoo porn online, right?
At the moment, we have two single women from out of state lined up who want to visit and try our boy. It just hasn't transpired yet, because of Covid.
