Dog aggression (original) (raw)

Dog aggression expressed by dogs is considered to be normal behaviour and various types of aggression are influenced by a dog's environment and genetic predisposition. Dogs commonly display possessive aggression when defending resources or themselves. Canine aggression may be influenced by a dog's age, sex, health and reproductive status. Canine aggression is one of the most serious behavior problems in animal behavioral medical science. Aggression in canines is particularly important because a dog's sharp teeth can result in serious injuries, or even fatalities in the young or frail.
