@Alexandra316, I just went to your listings and pretended to be a typical guest who, as we all know, just skims quickly. In doing so, it wasn't apparent to me that you allow dogs, although as you said if someone were to use the search function for 'pets allowed,' your space would appear.
Personally, when I travel with my dog, I have a tendency to message a potential host just to double check that dogs are indeed allowed or if not, I'll mention it in my initial message to the host that "I'm coming with my 50-pound dog......"
I would also, as others have mentioned, include in-text somewhere more prominent that dogs are permitted.
Btw, have you had any issues with pets? I'm considering permitting pets on a case-by-case basis, but concerned about it.
