i know this is not sticking to the subject but another thing to take into account i think is when you go to see a litter and everyone looks for the puppy that comes forward and plays, but what happened to me quite a few years ago was a puppy that hid in the corner and would not come see any one and all brothers and sisters where sold and she was left behind we where not going to buy that day just look {as we feel you should go see as many litters as you can to expand your knowlege as much as you can right from they are babys] we watched this lady with the litter playing with the others  she never had a litter before we asked about the little girl in the background and where told :cant sell her no one wants her  we took her home there and then she never did come around with adults BUT her secret was with childred with sp needs in a little school just down the road from where we live  she was frighted of ----people ,cars , travel,  didnt leave the house only to see the children she turned out to be the most beautfull shaded red  shape ,coat , everything  but a brain that was playing tricks on her every day of her sweet life she died a few years ago now but i like to think we gave her a chance to shine with the children when no one else would so re;; puppy or old chow for me it doesnt matter  you help where you are needed and somehow we always find them or they find us  we will aways be there just incase there is another little girl or boy out there  

Lovely story Teddy.
