I also have a Schnauzer at home. She is almost one year old and her name is Nicole! Today my girlfriend was video chatting with her mother on the balcony. They also have a dog at home named Luban. Then in the video, my girlfriend kept calling Luban, Ban, Ban, Ban! Nicole heard this several times and ran over. . . Later, my girlfriend and I tested it, and no matter what I called Nicole, she would come over. . .
