QWhen we meet people with dogs on walks, our six-year-old Lhasa Apso goes to the owner for a stroke or fuss, and if that person’s dog comes back, she will snap at it. Also, if I give attention to another dog, she’ll come over and push between us. What is the reason for this behaviour and how can I train her not to react in this way?
