Hello, I got a 3 month old Yorkshire Terrier about 10 days ago. Since day 2, she has growled at my family members, especially my Dad whenever they come up the stairs or into my room. I've tried shaking a noisy object to stop her as well as saying a firm no. I don't know what else to do so she'll stop. Any ideas of why she's doing this and what can solve the barking? I'd appreciate it a lot!
