If dogs are kept in a free range environment (wild), they will naturally live in mixed-sex, mixed-age social groups. Social ranking is determined by mainly by age, but sex is also a factor.
The role of the female is to guide the groups activities. Dogs are sexually mature between 6-9 months of age, however this can be longer for the giant breeds. However it isn’t until your dog is 18-36 months of age that they are socially mature. At social maturity the dog will fall into a natural hierarchial position, determined by sex, size, and temperament. In the wild dogs that try to challenge the social hierarchy wil sometimes leave the group and form their own pack, that is if they don’t suceed in altering the social order. This may explain the aggression sometimes seen in multi dog households. It is at the time of social maturity (18-35 months of age) that problem aggression and anxieties tend to surface,hence why socialisation through activities like puppy pre-school are so beneficial.
