the owner sounds like he knew he was screwed as he said he’d come back and hadn’t yet.
I’d say the blame is more with the entitled dog owner who needs to stop thinking he and his pet are so special that they don’t have to obey the laws.
Pedestrian trails and bike trails should be separate.
I’ve never put my dogs on a leash. They new the property boundaries and stayed there. You come onto mtheproperty then you get what you get.
They wouldn’t fit in a purse, kiddie cart etc because they aren’t dogs they’re cats that yip and they never went to a restaurant, pub or brewery etc. They stayed home loving life. Never had one for emotional support.. those people should be institutionalized.
I miss the dogs I had. They had long good lives.
Hope the dog is okay.
