Yeah, in that case, the best thing to do is get the owner. Do you live in an area where the animals have to be licensed? Call the cops on the license. If it makes the city some money in licensing fees, you can bet they'll listen to you! *g*

Sonic gizmos won't work. When dogs get in that 'kill or be killed' mode, nothing short of a steamroller is going to stop them. Imgaine dogs fighting, and you pointing a garage door opener at them. Same scenario.

If you have alerted the police, then you are well within your rights to protect yourself. Sometimes overkill works. I once had a neighbor with an angry Rottie who chased me every morning. She saw me several times chucking rocks at her dog. The day I started carrying a chunk of wood with nails sticking out of it is the exact day she chose to start fencing her dog. Problem solved. *bg*

I do wish you luck with this. Every dog needs a good safe place to go for a walk (and good people to take them).
