The rule in detail
Identification required (microchip or photos)
What the airline asks, separately
A carrier can require a document no state does. Most US airlines ask for a certificate issued within seven to ten days, whatever the state rule says. The two stack: satisfying one does not satisfy the other.
Dog breeds
Montana bans no breed at state level, but does not stop its municipalities from doing so either. Regulation therefore exists at city or county level, and it is the arrival address that decides — not the state, not the airport. Worth checking with the municipality before a move.

Common questions
- Do you need a health certificate to take a dog or cat to Montana?
- Yes. Montana requires a certificate of veterinary inspection, including for personal travel with your own pet, issued within within 30 days of entry.
- Can a dog breed be refused in Montana?
- Not by the state, but possibly by the destination municipality: Montana lets its cities and counties legislate on breeds. The arrival address decides, not the airport.
