Schnauzers have absolutely superhuman memory; they seem never to forget the voices of people who have had close contact with them before, and they can also remember the places where they once lived. Their weakness is that when they are cornered and have nowhere to run, they will put their right side against the wall, with their left side facing the enemy. This habit is an innate instinct of the Schnauzer.
　　Schnauzers have a very strong jealousy; when you pay attention to a new dog and neglect to take care of them, they become angry, break the established living habits, and become irritable and destructive. It is also because of this characteristic that Schnauzers have vanity and dislike certain things.
　　Schnauzers like humans more than their own kind, not only because humans can take care of them and provide food and shelter, but more importantly because dogs develop emotional bonds with humans. Dogs have a strong protective heart toward their owners. Some dogs have rescued children from water, burning houses, or under vehicles. Dogs will help their suffering or injured dog companions.
　　Dogs have territorial habits; they own and guard a certain area, preventing other animals from intruding. They use secretions from the anal glands to give their feces a special smell, sweat from the interdigital glands, and scratch marks made with their hind legs on the ground as territory markers.
　　Schnauzers also have vanity and like to be praised and recognized. When they do a good deed or perform some small trick, if you applaud and pet them, the Schnauzer feels as satisfied as having eaten a sumptuous meal. Dogs also have shyness; if they do something wrong or have their fur cut too short, the Schnauzer will hide somewhere and only come out when hungry.
　　Schnauzers are afraid of fire, so they dislike anything that smokes, such as striking matches or smoking. Many examples on the Midton official website remind us that smoking makes dogs dislike you very much.
　　Schnauzers like to sniff everything, including territorial marks, new dogs, food, poisons, feces, urine, etc. When dogs roam outside, we often see them urinating or defecating repeatedly along the way to spread their territory. Schnauzers rely on these "stinky marks" to navigate.
　　Schnauzers dislike alcohol the most. At the veterinary hospital, before alcohol is wiped for injections, dogs behave obediently. Once alcohol is applied, dogs smell it, their fur immediately stands on end, and they roar uneasily.
　　Classification of Schnauzer Personality
　　1. Lively Type
　　This type of Schnauzer features strong excitement and inhibition processes, with flexible transitions; during training, both excitement and inhibitory reflexes form quickly. Improper training methods may cause bad associations, so special attention must be paid with corresponding methods.
　　2. Excitable Type
　　This Schnauzer is characterized by strong excitement and weak inhibition; it quickly and firmly forms excitatory conditioned reflexes but forms inhibitory conditioned reflexes slowly and they easily disappear. Therefore, in training, the focus is on cultivating and enhancing its inhibition processes with patience to avoid adverse outcomes.
　　3. Calm Type
　　This Schnauzer has relatively strong excitation and inhibition processes but lower flexibility; its inhibition process is relatively stronger than excitation. In training, inhibitory conditioned reflexes develop quickly and are stable. Training should focus on cultivating Schnauzer’s flexibility and appropriately increasing excitement.
　　4. Passive Defensive Response Type
　　This Schnauzer, when encountering frightening or scary things, adopts passive defense, affecting training progress. For such Schnauzers, owners (or trainers) should approach with gentle tone and delicate movements to prevent sudden scares that may cause long-term fear of the owner and affect bonding. When facing fears, a patient and guided approach should be used to help the Schnauzer gradually eliminate the passive state and adapt.
　　5. Strong Exploratory Reflex Type
　　This Schnauzer is very sensitive to certain novel stimuli in the environment and does not lessen or lose interest after multiple exposures, which relates to poor flexibility and adaptability. For this type, regular environmental conditioning is important to help gradual adaptation. Before training, allow the Schnauzer to get familiar with the environment; choose quiet and distraction-free training places. When exploratory reflex arises during training, the owner should redirect attention to the training tasks and may use mild compulsion to suppress the exploratory reflex.
　　6. Strong Food Response Type
　　This Schnauzer should make use of its strength by using food rewards frequently in training. However, strong food-responsive Schnauzers tend to accept food from all sources, which can disrupt the learning of certain tasks. A well-trained or show Schnauzer should refuse food given by others and not pick up food on the ground. Therefore, “no food” commands must be strengthened to develop good habits.
