Running on a pack of dogs has both benefits and challenges. This is particularly true in the stronger minded breeds, such as the Chow Chow.
Over the years it has been most interesting to observe interaction in the pack and thus learn dog language.
Senior dogs have as much value as other dogs in the pack, and then some more. They are more relaxed in temperament as the over eagerness of youth has dissipated. Thus they teach the younger dogs how to behave calmly in various situations. And in the process of needing to teach individual characters, they learn new tricks in effectively getting their point accross.
They also teach the younger ones how to play, when to stop playing, and how to "speak" politely when communicating with another dog. They teach manners and obedience - also with respect to humans. They effectively teach younger dogs how to thrive in a human's world.
