"re-programming" a 10 year old dog who now finds everything he has been allowed to do (possibly encouraged) his whole life is now wrong is like taking a 90 year old man and forcing him to change evrything he has spent his whole doing and believing in and saying times have changed you have to be re-programmed, all this over a women (you) wanting to hang out with yr romantic ineterest - as a guy i would tell YOU to go take a hike and just find another woman and leave the old dog be.
sounds harsh i know and explains why i am a long time single guy no doubt - good dogs are hard to find.
This is a dog that now controls its owner, the household, and that decides who can come to visit. This is a dog that every day subjects his owner to a lawsuit and lifelong regret for injury to a child or friend. When the dog decides the owner's overstepped the line on a correction, there is a likelihood of handler aggression, the road of no return.
However this dog may have started his life, he is not now a "good dog." He is a liability.
