It lasts longer. Cars can last several years but we generally get rid of them as soon as they wear down or we tire of them. It can't be traded in for a newer model. A dog will be part of your intimate family for years to come and should be with you, barring any unforeseen circumstances, for its entire life. It comes with a personality.
Cars come in different colors with different options but all are basically identical.
Each Border Collie is unique in and of itself. Our concern is for the welfare of the dog in particular and the breed in general. Poor and hasty choices, along with nondiscriminatory matching policies are the biggest cause of returned or abandoned dogs. Though rescuers sometimes continue to monitor the adopted dog's early progress and hope you keep in contact long into the future, it is their mission to ensure that each dog is placed in a loving home and will not need to be removed for any reason. Like adopted children, their long-term placement in a caring family is our highest priority.
