Come to think about that: to operate a car, motorcycle, boat or aeroplane you need to get a license, proving that you know what you are doing. Depending on vehicle and jurisdiction, you might even need to re-take tests frequently. All of these vehicles (in most jurisdictions) require frequent inspections and if they fail these inspections, you are no longer allowed to operate them.
Also, there are very stringent laws on how you are allowed to operate these vehicles, with really harsh fines for violations of these laws.
Looks like your stance on dog ownership is much more hardcore than mine, but I could get behind that.
