Leslie, I do not know enough to form an opinion on why this is suddenly occuring. It may be that Kersey is feeling the stress of all that has been going on in your families life but then again it may be something totally different. I would really like to understand better so bear with my extra questions.

1. How old is Kersey (approximately)?
2. How old was she when she was given up by her previous owners? Or How long was she in the shelter?
3. Do you know anything about her past history before you got her?
4. How is she with Graham? Does she try to be the alpha dog over the two of them?
5. Does she obey you when you give her a command immediately or does she do it when she feels ready too?
6. Is she spayed?

I am really interested in knowing how Kersey and Grahams relationship is.

Thanks for the additional info. I will write more after I get your answers.
