Dogs generally don’t hold grudges.
Because the dog’s memory is divided into three types: current memory, scene memory and end point memory. They are limited by the range of their field of vision, limited memory extension ability, and are more affected by the surrounding environment, so dogs generally do not hold grudges. However, if a dog is beaten for no reason for a long time, the dog may become restless and sensitive, distrust humans, and in severe cases may self-mutilate and attack humans.
