No, don't bother trying to use Airbnb this way. You'd have to send fake booking inquiries to each individual host, and honestly hosts really hate that. If one reports you, your profile could get banned from the site.
You might check social media to see if there's a home sharing group for your region, and discuss the topic there. But I don't quite understand why you perceive a problem with guests not knowing where to walk their dogs. Are pets forbidden on the regular trails and streets in your area?
