someone's dog pulled out of their harness and attacked me because it didnt like the sound of my skateboard

it seems like people should be buying better harnesses

If you know of any, let me know. The problem is that any harness you buy will get more loose as it is warn, and panicked dogs can get out of a harness the same way you can get out of a t-shirt: line your head and arms up along the same axis and back up. A harness is only really effective if the dog is moving forward and away from you, not if they are backing away from you in a desperate panic.

A few weeks ago was the fourth of July, maybe it wasn't that random.

On the 4th, it wasn't random. The days following? I can't predict when fireworks are going to go off. (That's irrelevant anyway, as the dog needs to go out regardless of the date.)

Sounds like your dog is the problem here.

My dog is a 1 year old animal. Of course he is a problem. But he isn't the one exploding shit to amuse himself.
