This has to be met with full resistance, it's been allowed to escalate and will only get worse. There are humane deterrents (light, sonic) online, but you have to make life miserable for them enough to leave. Get a 100k Lumen Flashlight 2 for $15, and Pepper Gel 2 for $15 for walks.

Use pepper gel in case of close engagement- aim the stream at center mass of his body, not the face. You dont want it to collapse, you want it to run away.
