Ever since I adopted my Purebred Treeing Walker Coonhound, every time she see's me she always rolls over and shows me her belly. While she never seems to challenge me or anything she is starting to growl and nip (but she never nips hard enough to hurt, she just scares them) at the rest of my family, she leaves my cat, cockatiel and goose alone but is starting to..i guess be aggressive towards the humans. Any reason why? They all do the same things I do when around her, and i have started modifying the ways they act around her to see if it goes away....any suggestions?

Well she has done the belly thing ever since I got her from the shelter, she has never been beaten or slapped...she has been corrected when she does something wrong but only by removing what she did and giving her a sharp NO or Bad. Please don't think that I am hurting her cause I never would, she is my first dog that I have had to beg my dad for years to get.

And I've noticed that its really only men that she growls and nips at. Would that be normal of a female?

....since you've had her in your home. Do you know her
situation before she came to you? Unlikely, but it's worth
asking.

While you're following Dogman's advice about getting a good
one-on-one assessment, don't do that. Don't put her in a
situation in which she may become scared of you and your
family. That won't help the situation.

Many dogs are more fearful of men than women. Men tend to
think that punishment and consequence is the first recourse.
Men tend to think that a hearty slap on the side is
commardrie. Men loom and talk deep. Men get pissed off when
the dog doesn't immediately take to them.
