Lexi is my wifes dog, yet my they have been having issues. Lexi will obey me fairly well, yet seems to always push my wife.
After watching them we are working and more praise and consistence on the part of my wife working with her.
Also noticed confusion with lexi when my wife called Lexi to her. Lexi knows 'here' as the come command. Yet my wife told her 'come here' and Lexi stood by the door looking confused. Seems my wife has been telling lexi 'come on lets go' when they leave. Appears inadvertently lexi as picked up 'come' as get ready to go.
So will continue to work on human consistency of word usage, praise and setting conditioned punisher.
Also realized since dogs often seem to naturally gravitate towards me I need to do much less with Lexi.
