We live in the main house on our property, and rent out a 2 bedroom apartment over our detached garage. The apartment has its own private entrance, parking, deck and walkway to the beach. We have three dogs on OUR property that don't access the apartment area at all. However, I do fully disclose that we have three dogs, and that they will see you as you pass by our property (the walkways are next to each other like all beach properties, but being on one lot they are closer together). And when they see you they will greet you the first few times.
My dogs are very friendly, occassionally bark when you walk past until they are shusshed. and nearly every single one of my guests has stopped to pet them and speak with them on their way by. In fact, a few have even asked if they can take them for walks on the beach.
I guess my point is that I felt it was better to fully disclose the presence of my dogs so that guest would know ahead of time what to expect. I figured it was better to disuade a guest from booking my property if they are afraid or dislike dogs rather than deal with upset guests or receive negative reviews.
I would include your dogs in your description, and offer a full disclosure description of when, if, and where your guests might run into them.
Best of luck!
