hiya. Ok i.ll start with a bit of history to try and make it a bit clearer. About 8 months ago i got me a cute, funny doggy called pop, who needed a new home. She is a right little "buggerswine" at we call her she is nearly 6 now, we think, and in the 8 months i.ve had her she has come on fantastically. She has learnt heel off lead, can do a load of tricks, has learn.t about not stepping off the curb until i say. She is great with my older brother who is profoundly autistic and frightened of dogs. She is so gentle and gives him his space. She.s loyal, obedient, loving and very submissive with family. Too submissive, she flinches quite alot, especially when you walk near her with something in your hand. She will quake and hit floor or roll onto her back. So i think something has happened to her at some point. The real problem is her need to bark, in the house she silent, she scares the hell out of me some days by sneaking around. But outside she is loud. She is very dominant with all other dogs even familiar ones. She barks constantly i.ve taught her the command "quiet" and any other time she does so immediatley. But when other dogs or people she decides are bad, she seems unable to stop. She will go quiet for a few seconds then start up again. I dont think its aggressive with other dogs its just her being dominant. But i just can.t seem to break her of it. Also if we are out and its dark she will loudly growl at any men passing. What should i do?
