I live in a Town Home that is surrounded by college students. There are "No Dog" signs around the pool but they never enforce it. The homeowners pretty much want to do as little as possible around here. What actions can be done to keep people from bringing their dogs to the pool legally?
This will typically depend on the city and county regulations. However, this does pose a clear health risk and you can contact your health department. If nothing else, they can help to educate the pool maintenance staff to the risks of having dogs in the pool on a regular basis. Perhaps that would motivate them to enforce the regulations a little more.
