Welcome to YT! Sit your yorkie down on a sofa and talk about her mother with her- lol j/k
Is your girl a new addition or have you had her since she was a pup? My boy thinks he is king of the neighborhood and barks even at the great dane that often walks by! When they named them they meant to call them Yorkshire terrors but something got lost in translation
It sounds like your yorkie thinks she is boss. You must establish yourself as boss. Something that has worked great for me is when I take my terror on a walk I walk him
right beside me or a little behind but I do not let him go in front. If I see him notice a dog or a person and start to get irritated I pull him to the other side of the sidewalk and use my leg to block him from going after them. I gently tug on his leash and say 'no'. If he lets the person pass by I praise him for a job well done. Teach her some basic commands, let your husband do them with her too. If she is growling at him he should not back down, he should go sit next to her until she stops then praise her when she is behaving well. Don't let her on your lap or near you when she is being like this. You need to teach her growling is not going to get her what she wants. Welcome to YT!
