The Bottom Line: Londonderry lands in the lower tier of our national comparison. That usually means one or two structural constraints, such as extreme weather, higher recurring pet costs, or breed-law friction, are doing most of the damage.
Londonderry ranks #3602 out of 4,184 analyzed cities nationwide. Inside NH, it currently sits #9 out of 15 cities in the representative state set.
Londonderry has a fairly balanced climate by our scoring model, with 214 walkable days per year. Most owners can expect standard seasonal adjustments rather than year-round weather disruption.
Care is available, but it is not especially cheap. Local pricing runs above the national baseline in our model, so routine visits and emergency care are more likely to feel expensive than in mid-cost markets.
Housing and policy matter here too. Renters should budget for roughly $67 a month in added pet surcharges, which puts this market on the more expensive side of dog-friendly housing.
Londonderry sits in rockingham County, and that local context matters because city-level pet friendliness often swings on county housing pressure, clinic supply, and climate. We do not estimate a strong dog-park footprint here, so the community layer depends more on housing flexibility and nearby alternatives than on obvious off-leash infrastructure. Cold conditions drive the walking pattern here, with 22 very hot days and 52 very cold days in the annual weather window.
