Dog
Dog ownership initiates what economists classify as a non-discretionary recurring obligation. Daily requirements include two to three walks totalling 30-60 minutes, feeding at consistent intervals, fresh water provision, and social interaction sufficient to prevent the development of destructive behaviours. Annual veterinary costs average $700-1,500, with food expenses adding $500-2,000 depending upon size and dietary requirements.
Beyond scheduled maintenance, dogs generate unplanned demands: midnight bathroom emergencies, consumption of inappropriate objects requiring surgical intervention, and the inevitable carpet incidents during the training period that owners describe as lasting significantly longer than the literature suggested.
Toilet
The toilet requires remarkably minimal intervention for the service it provides. Weekly cleaning prevents the accumulation of biological residue. Occasional replacement of the internal flapper mechanism, at a cost of approximately $15 every five years, maintains flush efficiency. The average toilet operates for 25-50 years before requiring replacement.
Water consumption represents the primary ongoing cost, with modern low-flow models using merely 1.28 gallons per flush. Total annual operating expenses rarely exceed $100, a figure that includes cleaning supplies and occasional plunger deployment.
VERDICT
The maintenance disparity proves mathematically stark. A toilet costs less annually than a single month of premium dog food.
