Some of my friends are dog owners. Many love their dogs and are quite aware of the responsibilities incurred with it but still tend to complain about the timing issues of taking care of their pet.
Having a dog is sometimes like having a child; you have to feed it, wash it, and also take it out to take care of its duties. The latter could be compared to diaper changing which is crucial and necessary with babies.
The owner of this video may be lazy, innovative or perhaps a multi-tasker. Their solution to taking out the dog for a walk is to tie the leash to a remote control car.
While having fun and playing with their toys, they are are also taking care of their pet owner responsibilities.
The only thing is, I am not sure the dog is enjoying or understanding what is really going on. I guess it depends on the pet.
