After years of struggling to justify the cost of dog ownership, I have compiled a list of chores for my dogs to do that save me money and time. Training was simple, since most duties are derived from their natural instincts. I find myself with more time, more money and less stress. Most dogs would love to be productive members of society, if only humans would let them do their thing.
I no longer buy vacuum bags. My dogs eagerly take care of accidentally dropped food. They will sit under the table at mealtime to provide our family with instant clean up service. As a bonus, dogs will also clean up other dropped items besides food, like pencil erasers and thumbtacks.
