While I support leash laws, I don't think they're a solution since they provide a false sense of security and only define responsibility...without really protecting anyone.

I advocate the deterrent approach.

Today, I resolved to buy pepper spray after being charged hard by a dog that came out of nowhere...right on a double curve with gravel! I've not heard of the whistle, but I'd consider it as preferable if it wasn't too big, simply because it doesn't require aiming.

Broken pelvis! Yuck...isn't that a very long recovery period? Glad she's OK, but I certainly wish it hadn't happened.
