Sprayed Neighbor In The Face With Hose

Neighbors dog tries to get over our back fence when my children are playing in the back yard. It's gotten to the point where they won't go out side because they are scared of the dog actually making it up over the fence. Today I got tired of it and sprayed the dog with a water hose while watering my rabbits, the owner came out screaming and cussing (I've told her and her husband many times about the issue). The argument led to her spraying pepper spray at me with my toddlers a couple feet away, she missed but I didn't want her to try again so I soaked her with the hose until she got off our fence. It's a bummer situation but I reached my end in that moment. Any suggestions on how to move forward to a solution?
