Where the numbers come from
Each estimate adds up typical US price ranges for the main costs of owning a dog, scaled by size. Giant breeds (100+ lb) cost the most because food, medication and boarding are priced by weight.
- Biggest swing: dog walkers and daycare can cost more than everything else combined.
- Biggest surprise for new owners: emergencies. A single emergency vet visit can cost $1,000–$5,000 or more.
- Biggest savings: adopting instead of buying, and grooming at home.
