hey...well the puppy turned out to have an infection...shes on meds now so should be getting better i hope. my question now is about dominance issues. she is still a very young puppy, but seems to listen to me well when she is play biting or something, but when she is with my girlfriend (who has spent as much time with her as me) she doesnt listen. she has "attacked" her pants legs a couple times and tried every method to get her off but she wont listen or be redirected. she wont do this when im around or do it to me in general. which leads me to believe that maybe she thinks she is the pack leader instead of my girlfriend. this issue obviously needs to be corrected asap. i will deal with it now, but not if it continues as she gets older. is there a good way to teach her whos boss? any help would be great.
