Abundant giant schnauzers are dominant or aggressive toward other dogs of the same sex. Some have a powerful chasing drive and can chase and seize cats or alternative animals that head for the hills from them. Because it’s an outsized dog, it is capable of seriously injuring or killing other animals. Responsible breeding and correct meeting and coaching square measure vital to curtail this instinct. They are best for one-pet homes and should always be kept in a fenced yard and leashed when out walking or jogging.
