Invisible fence in front yard

[exboyfil]

3. The dog had the collar

and the owners claimed they had the fence. The dog must have been receiving quite a shock though (guess it would depend on the setting). I am going to do some research on the pedestrian right of way and the leash law before calling the police I will give whatever info I find out to the dog owners if it shows they have a problem. I don't like to escalate situations if it can be avoided. I do know that my daughter was on the sidewalk with a approximately a 4 foot leash (it is shorter than my leashes). Both dogs were biting at each other.
