Dogs from puppy mills most commonly come from large kennels where they spend 24 hours per day inside wire cages without any human interaction or stimulation like dog toys or dog walks.

They are not exposed to other dogs but instead, they live with their species which makes it extremely difficult for them to interact with humans once they have been adopted out of the puppy milling environment.
