Factors Contributing To Aggression
Factors contributing to the likelihood of the development of dog aggression include:
- Anxiety, fear or phobia
- Lack of structure
- Lack of proper exposure to other dogs during the critical socialization period
- Early imprinting by an aggressive or nervous dam
- A traumatic experience
- Territorial behavior
- Thyroid malfunction or other medical conditions
- Abuse from owners
- Medical or physical ailments
- Breeding and genetic predisposition
Dog aggression manifests at the age of adolescence to social maturity (6 months to 4 years). Warning signs such as fear and/or nervousness around other dogs, displays of aggression only under certain circumstances (while on leash, in the presence of food, in the presence of the owner, etc.), or most commonly, over-the-top play behavior can be seen at any stage of the dog's development. Play behavior such as tackling, chasing, mouthing, nipping, pawing, and wrestling are all normal canine behaviors that serve the evolutionary function of preparing the young dog for later combat and hunting. Young dogs that engage in excessive amounts of these behaviors are much more likely to develop dog aggression as they age.
Dog-dog aggression should not be confused with dog-human aggression (in the past, this was referred to as "dominance" aggression when directed at the owner, but is now simply called owner-directed aggression).
Many people commonly mistake fear and anxiety-related aggression as "dominance aggression," which is inaccurate. Dominance is rarely the cause of aggressive behaviors in dogs, with fear and anxiety being the greatest cause of both dog- and human-directed aggression.
Lack of exercise is not a cause of aggressive behavior, although exercise boosts serotonin levels, which offset stress hormones such as cortisol, and can complement a behavior modification program. However, it is a common misbelief that aggressive dogs are "not exercised enough." Many aggressive dogs are exercised regularly.

Famous quotes containing the words factors, contributing and/or aggression:
“I always knew I wanted to be somebody. I think that’s where it begins. People decide, “I want to be somebody. I want to make a contribution. I want to leave my mark here.” Then different factors contribute to how you will do that.”
—Faith Ringgold (b. 1934)
“[Girls] study under the paralyzing idea that their acquirements cannot be brought into practical use. They may subserve the purposes of promoting individual domestic pleasure and social enjoyment in conversation, but what are they in comparison with the grand stimulation of independence and self- reliance, of the capability of contributing to the comfort and happiness of those whom they love as their own souls?”
—Sarah M. Grimke (1792–1873)
“In any case, raw aggression is thought to be the peculiar province of men, as nurturing is the peculiar province of women.... The psychologist Erik Erikson discovered that, while little girls playing with blocks generally create pleasant interior spaces and attractive entrances, little boys are inclined to pile up the blocks as high as they can and then watch them fall down: “the contemplation of ruins,” Erikson observes, “is a masculine specialty.””
—Joyce Carol Oates (b. 1938)
