Sadie's not possessive of me. she does hate cats i think because she tried to attack one that i tried to bring in off the street. but she's rather tame really.
 
i know she'd protect me from strangers that were trying to hurt me, but not just bark and growl for no reason. 
i've seen episodes of It's me or the dog with Victoria Stillwell about dogs that are posseive of their owners, in these shows it's a bad thing because hubbies nad kids could get hurt or bitten over it. i hope that your situation is not that bad, but it might be if you can't figure out how to get Yoda to let you have a life 
 
good luck hope he lightens up a little bit soon 

 check out Victoria's suggestions for this type of behavior if you need some help. i think she's just great.
