Was walking in a park just now. Saw a man walking, then looked to my left and saw about 15 meters away, a black German Shepard charging towards me at full speed. Terrifying, l shouted to the owner, put him on a lead. Then the dog charged again. It's was very frightening, a fully grown big dog making a very fast bee line towards you. Time sped up, l sort of did a standing phoetal pose. I shouted again, put your fucking dog on a lead! The man said quietly, lm very sorry. My adrenalin was pumping, l was hyperventilating. Just posting to get it out of my system. It was a young dog but fully grown. Please keep big and young dogs on leads. If that happened to a young child, it would be awful!
