| Not a drive issue, you are describing something a dog is trained to do. Not all teaching/training is based on drives. Mine pull because I harness them up and them to. Dogs were used to pull carts because the owners found it useful. A dog was cheaper to feed and smaller to keep than a horse.
Please, refer to Mick's initial definition. " Drive: "describes part of an inherited trait which serves to sustain life and species". It is where the dog is exibiting behavior where it has a sole focus to achieve a desired goal. " |
