Dog
Dog maintenance constitutes what economists term a substantial ongoing commitment. Daily requirements include feeding, walking, attention, and the management of various biological outputs. Annual costs range from $1,500 to $4,500 depending on size, health status, and the owner's susceptibility to premium treat marketing. The dog cannot be stored in a cupboard during holidays. The dog develops opinions about veterinary visits. The dog sheds.
Furthermore, dogs require training, socialisation, and the navigation of complex behavioural needs that no instruction manual adequately explains. They are, in maintenance terms, a lifestyle-defining commitment.
Pillow
Pillow maintenance approaches the theoretical minimum for any comfort-providing object. Requirements consist of occasional washing, performed perhaps quarterly by conscientious owners and never by a statistically significant proportion of the population. Replacement every one to two years maintains optimal support. Total annual cost: approximately $20-50 for standard pillows, rising to several hundred for specialised orthopaedic variants.
The pillow requires no walks, produces no waste requiring collection, and has never once demanded attention at the precise moment its owner attempted to leave for work. It is, in maintenance terms, functionally negligible.
VERDICT
The mathematics here permits no dispute. Pillow maintenance involves occasional laundering. Dog maintenance involves restructuring one's entire existence.
