a girl was walking a dog in the parking lot earlier, an American Bulldog that lives in the building that I have personally fallen in love with (he's gorgeous but I have yet to creepily sneak a photo). the girl walking him, I've never seen her before, but the owners of the dog let another couple in the building play and walk with him sometimes when they aren't around and I think this girl was their friend. anyway, the dog is too big for her, and was pulling (not much mind you, but enough) so she took the end of the leash and started hitting him. she hit him over the back, on the legs, and on the face/head. after the first hit the dog stopped, and she didn't. if you see someone do this, what do you do? do you call them out? offer advice if you can? let them know you saw that? or do you just keep going and hope that's the only time it ever happens and that the dog doesn't get fed up with it, turn around and snap at her? ETA: this dog doesn't pull with his owners. I thought maybe he saw something, but they weren't close enough for me to see what it was. usually, he is perfectly well-behaved. I know he's not neutered, and I know there's a female downstairs that hasn't been spayed yet so I thought maybe that might be it.
