Next time it’s loose and you have your dog, I wouldn’t try to hurt the other dog necessarily, but I’d rush it/ charge it in a way to where the owner wasn’t comfortable leaving it off the lease around me anymore.

I’d do this while not saying anything to the dog or the owner. The dog will run away, just trust me. Owner will probably yell and call him/her. And I’d carry on my walk with my dog without acknowledging the owner or what just happened.
