Needing help with aggression
Hello everyone, sorry it's been a while things have been hectic around here a lot of last year was spent taking care of my senior girl and i sadly lost her around Christmas. I have lapsed on my chihuahua boy a bit and was wondering if anyone had advice. My niece is with me everyday, until I move next month, whenever she lays down he will lay on the back of the couch and growl at everyone. If you walk toward her for any reasonhe will jump down on top of her barking and lunging at you. It freaks her out and it really upsets me. I don't know what to do to not escalate the issue or scare him or her. Any advice? I'm considering calming chews but I'm not sure how well they will work on him.
