I'm afraid it's a thing dogs do, some years ago we werevisiting one of my nieces when one ofher friends was litteraly dragged in by her by her dog, a gorgeous long haired G.S.D bitch puppy she called Hailley, who galloped round the room saying hello to everbody before settling on me ( she must have known i'm a sucker for G.S.D's) any way after a while being told how they were struggling with her etc etc I decided to take her for a walk while the ladies had a "girlie" talk so off I went and,after hearing Danielles' tales of woe I couldn't believe how well she behaved when I was well clear of any roads I even took the risk of letting her off the lead and she was perfect, running off chasing sticks and playing but comming in as soon as I whistled. On returning to the house I met Danielles' husband who said he'd passed us in the lane and nearly stopped to ask what I was doing with his dog then decided the dog was just a look alike as it was too well behaved to be his. I saw them In the pub a few days later and they wanted to know how I did it because as soon as we left she reverted to her normal behaviour, but persevere masma, Hailley eventually settled down and became the sort of dog you could be proud to take anywhere and I'm sure Coco will too (once shes' got you where she wants you)
