Sector Primers — The $100B Dog

The dog-care economy is not a monolith — it is a stack of operating sub-sectors, each with its own structure, growth rate, and degree of consolidation. Making the whole legible starts with mapping the parts.

The sub-sector map

FoodSourced

~$40.9B U.S. dog-food sales (2025)

The largest, best-measured slice — ~69% of the dog+cat food line, ~2.3× cat food. The dog majority on the dollar axis. (Euromonitor)

ServicesSourced

Lead growth driver of pet care

Grooming, daycare, training, walking, boarding — the operator layer, and the part of pet care growing fastest. (Morgan Stanley)

Boarding & KennelPartial

NAICS 812910 · fragmented base

An overwhelmingly independent, mom-and-pop operating base — the “Step 1” sector of the recognition staircase. Structure sourced; sub-sector dollar figures in research.

VeterinarySourced

~$41.0B U.S. vet care & product sales (2025)

One of the largest single slices of the $158B U.S. pet-spending total, projected ~$42.4B in 2026 — defensive and consolidating. (APPA; a care-plus-product bundle, derived from Packaged Facts.)

InsuranceSourced

~5.46% of U.S. dogs insured (2024)

A low base compounding fast: North American written premium rose 20.8% to $5.2B, ~91% of it in the U.S. The humanization proxy — the penetration gap is the runway. (NAPHIA)

Health & PharmaPartial

~$13.0B U.S. animal-health market (2021)

Medicines, vaccines, and diagnostics — ~32.6% of the ~$39.9B global market. Spans companion animals and livestock and dates to 2021; a dog-specific, current figure is still pending. (Animal Health Institute)

On the “Partial” tags. Per the library’s discipline, a sub-sector dollar figure is only shelved once it traces to a named primary source and clears a verification pass. Food, Services, Veterinary, and Insurance now carry verified primary figures; Boarding & Kennel and Health & Pharma stay partial — structure sourced, or a dated/broad figure sourced, with a clean current dog-specific figure still pending. The structure is real; the placeholders are honest.
