Hey I have a 75/80 pound Yellow Lab that is VERY protective of my girlfriend, her children, and myself. We do not have a fenced in yard as we are currently renting, but have the dog on a leash every time she needs to go outside. We have posted multiple no trespassing, beware of dog signs in both the front and back yards. I have locked the gate that leads from the front to the back yard, posted a no trespassing sign and beware of dog sign on this gate as well. I have also posted a no soliciting sign on the front door also (that nobody looks at and they act surprised when my dog bears her teeth to them at the door). Now we do love her being protective, and believe it or not she is extremely loving to both of our families also. My thing is I want to know what needs to be done, in case a child (which is my biggest fear) or any other party were to walk in our yard after these signs were posted and if something were to happen while she was on the leash around the posted signs. What kind of liability would I be looking at? Also if someone were to break in and she were to tear them up defending the property and it's occupents I want to make sure that there would be no liability there as well. The county I live in is Santa Rosa in Florida. Getting rid of the dog is NOT an option and we are working with her on this as well. Any input would be greatly appreciated.
