I'd like the name of that gene form the dog genome project-
http://www.ncbi.nlm.nih.gov/genome/?term=canis%20lupus%20familiaris
http://www.genenames.org/useful/genome-databases-and-browsers
Then we could screen baby (humans or dogs or cats) to see if they have the 'aggression gene marker' and take appropriate actions...
All Terriers are smart, active, suborn, and breed to be people pleasing - the need jobs and structure- socialization.
Each was bred for a specific job and that job has changed over time, like greyhounds were not bred for tracks originally - they were bred to see and weary prey.

Anyway I do not allow children under a reasonable age, (depends on the child) around any animal (depends on animal) unsupervised ever- that particular dog I would keep on a leash around any strangers then I control the dog and can also control the intensity of the meeting, I'd have the dog create trained and create if the dog is to excited.
