Well, my opinion is far from some of the more experienced on here, BUT...my boxer, Shelby, is the same way. My husband and I play wrestle all the time and she will go after him in a minute if she thinks he's hurting me. Now Koda on the other hand could care less. And Shelby is the same as you said Bubba was...if I pretend to hit my husband she doesn't care and won't react. She will also go after him if he does this to our daughter.
