  • Complete case histories from 120 dogs referred because of aggression were reviewed to determine what trends, if any, were present. Sixty percent of the animals were male, with the remaining 40% divided almost equally between females, neutered males, and neutered females. The mean age for dogs presented was 3.0 years, although females tended to be younger and neutered males somewhat older. Mixed-breed dogs (18.3%) were the most common, while Cocker Spaniels and German Shepherds (10% each) were the most commonly seen purebreds. Attacks or threats were directed to adults by 54.2% of the dogs, toward children by 21.7% of the dogs, and toward other dogs by 41.7% of the patients. Twenty animals (16.7%) threatened more than one category. Competitive (dominance) aggression, the most frequent type diagnosed, was expressed by 59.2% of the dogs and was generally responsive to treatment. 1983.
