I wouldn't be surprised if it also happened precurrency as well. We aren't dogs but one thing known to make them potentially more aggressive is having larger "territory" it thinks it must defend.

That was useful behavior for guard animals but not universally For vast periods of time you want them to bark at intruders, cattle rustlers and predators but not mauling small children or innocents who may leave you liable.

Essentially it may be the power that does it technically.
