I was wondering if there is an age when a border collie becomes really biddable. I have an 8 year old dog I bought when he was nearly two years old. He is and always has been, for as long as I've had him, a very biddable, sensitive affectionate dog. I also have a nearly 9 month old pup. He obviously has his own personality etc. but I was wondering if it is anybody's experience that the biddableness comes with more time than 9 months. I know it wouldn't be fair to judge an entire breed by one individual dog but I was under the impression that all the great things I love about my older dog are very typical border collie traits. To be honest, I am kind of disappointed with my younger pup. I wonder if he is just a hard dog or perhaps I just didn't do as good a job raising him as my older dog's original owner did raising him. Or, hopefully and my main question, does the biddableness/sensitivity come with more time? I appreciate any input. Thanks
