I am amazed at the number of knuckleheads who let their dogs run around, unleashed, with the owner nowhere in site or "worse" think every dog wants to play with their dog. Here's the scenario: The Ghillie is running on the beach (herding the surf) while I keep watch over him. Along comes another dog and owner. The owner sees Ghillie running, unclips his/her dog and says "go play with that other doggie". After the dog has taken off after Ghillie, yipping/yapping and being a PITA the other dog-owner asks "Does your dog like to play with other dogs." I reply "He does not." "Oh? What does he do?" "He ignores your dog until your dog has become an irritant. Then he turns and says, in doggy talk "Piss off, wanker " Usually a few seconds later Ghillie bares his teeth, growls and chases the other dog off. It matters not how large or small the other dog is, Ghillie accepts no interference in his work. Oh, and he's just as uninterested when he is at home in his yard. Neighbors do not bring their dogs to play because The Ghillie has made it clear he is not a playmate he's a work-a-holic. Happily though he "works" well with other BCs and some shelties.
