From a dog’s point of view, a human’s “job” is to provide endless personal services to the canine members of the household. We seem to think we have them trained, but with a dog in the house you quickly realize they are in charge and we are just the servants who love and care for them. Their needs are our commands. If we do not do our various jobs properly, they will let us know. No complaints from us are allowed. We live to serve our dogs and do it with a smile.
Humans have two hands with ten fingers. That means we have multiple digits created just for scratching a favorite spot behind a dog’s ears, or a good spot on their back or stomach. A full massage is always nice too. If those hands are occupied with some mundane unnecessary task, we must immediately set that aside and perform our assigned duty of petty and scratching. The exception is if our hands are busy getting them their CANIDAE meals or treats. Then the lack of required petting and scratching is temporarily forgiven. They consider themselves reasonable bosses, after all.
