My question involves real estate located in the State of: California
My neighbor behind me that has a pool a pit bull dogs does not want to response to my plea to fix our shared fence. I'd like to replace it if possible 50/50. I have 3 kids all under 5 years old who play in the backyard swingset. Sometimes i find their pit bull or other dog in my yard which frightens me. They have a pool and Im wondered that worse case scenerio, one of my toddlers could drown in their pool.
How can I get them to finally do their part in resolving this issue?

So, if the neighbors don't recognize this hazard already.....
