I used to walk a young bull terrier on a disused rail track, straight and see for miles. A horsey type old bag let her standard poodle run about 200 hundred yards and set about the pup, she did f**k all my dog was on the lead and thought it was great but did not really know what to do thankfully. A month or two later she lets it run over and knock me off the bike as i am excersing the dog, same carry on. Final time the dog is grown and knows whats what and would destroy her daft poodle, i see her about 200 yards away and start shouting to put her dog on the leash, she takes no notice of course
