My wife is continuing to work on building a better relationship with Lexi, by doing more play and fun activities.
Lexi is a very head strong, physically strong, energetic and intelligent dog. When Lexi wants something it is all my wife can do to hold her back. Choke chains, star marks or prong collars have no effect on her if she wants something (stray cats, small animals, to see someone she knows etc.) We have tested her enough to know she knows all her commands. When she is in the mood and no distractions she obeys them perfectly.
It is hard to find what will motivate her as it changes day to day.
We are thinking we may have to build a small agility course, and or do scent work to give Lexi something constructive to do.
