The problem with a LOT of dog owners is that they think people like their dogs as much as them ! and they simply don,t.When that large headed Labrador 'homes in ' on your privates you gently push it away and say 'nooo '.When you really want to smack it round the nose and yell at the owner ' can you get your dog's nose out of my f...ing bo....s ! (Thats presuming you have some,reword appropriately ! )
