Rex really changed the relationship between the dog owner and the dog pro..
Before Rex came on the scene,the dog pro was nothing more than hired help, probably one step ahead of the stable boy, but not quite the ranch foreman...during the days of the Murnanes,the Wallaces, and even the early years of the Belmonts, the dog pro served at the whim of the wealthy owner, one old timer told me that he even had to hold the folding chair for one of his wealthy clients and when his client decided where he wished to sit he would unfold the chair for him...
Well along comes Rex and his clients include those same wealthy blue bloods,the Belmonts, the Crows,the Ken Cory's and even a young dapper couple named Lanse Brown and his former wife Dana...along with up and coming stars named Judy Weikel and Delma Hazzard..the clients came to Rex, and adapted to his schedule, his terms..the Major was definitely in charge
When you really think about it Rex taught his clients, not only how to handle their dogs , but also how to train their dogs...Not too many pros have that distinction in present day time...they may show their clients how to run the dogs that they trained, but how many have taught their clients sufficiently to where they are able to go on their own, with very little if no need of the pros services..;-)
