Wanted to put a Like/heart to the first set of pictures.
Her crash pictures made it hard to click though.
Dogs and bikes.
I had to neighbor restitution buy a HarleyDavidon riding neighbor an new set of riding boot from a snapping biting by our AusiShepard dog. Got off lucky at that.
Then spent an actual $1,000 dollars upgrading that properties sides 550 feet of old five wire cow fencing to dog proof. Too many kids bicycle ride there now.
Tough problem you have now.
For her - an ammonia filled distance spray bottle until you can get it resolved.
Best of luck with the neighbor.
