Dog owner one takes her dog to the community park on the way to somewhere else (not the kids park part BTW but fields and gardens). Dog one is barrier reactive to other dogs if they run at it in a bonkers giddy but not nasty way. Dog one is fine with other dogs off the lead but will chase squirrels so on lead in this area.
Dog owner two comes on to the park and sees it as a place she can let her dog run free. One of the only places she can. She let's her dog off and it runs round the park repeatedly running at dog one who then diving about on a short lead and being a pain for owner one. She tries to shout him back but he doesn't come back and keeps running at the other dog for the entire walk through the park until dog ones owner leaves.
Is dog owner one at fault for taking their dog on the park when they know they might encounter off lead dogs who will run at them.
Or dog owner two for not having control of their dog.
