It might be a case of owners who never "had" to obedience train the
dogs. Now that they're in a more populated area, suddenly they are
embarrassed by the dogs' behavior and are trying desperately (via
yelling at them when on walks, etc) to make up for lost time and prove
to other people in the neighborhood that they're not just letting
their dogs run rampant.

It's a thought, anyway.

It's not so much they yell at them to discipline them but rather to keep
them from running off too far or into the street. There are three dogs and
they all go out at once with one human, who endeavors to keep track of all
three at the same time without using leashes. So one or more of them is
always getting too far away and must be called back.
