Montana Service Dog FAQ

Do I have to register my service dog in Montana?

No. Neither the ADA nor Mont. Code Ann. § 49-4-214 requires registration, and businesses may not demand it.

What can a business in Montana ask about my service dog?

Only two questions: is the dog required because of a disability, and what task is it trained to perform. No documents, demonstrations or pet fees.

Can I take a service dog in training into public places in Montana?

Yes. The ADA doesn't cover dogs in training, but Montana does under Mont. Code Ann. § 49-4-214 — a dog in training must wear gear identifying it as one, legible from 20 feet.

Is it illegal to pass off a pet as a service dog in Montana?

Yes. Under Mont. Code Ann. §§ 49-4-221, 49-4-222, it is a misdemeanor after a prior written warning: $50 first, $75–$200 second, $100–$1,000 for later offenses.

What happens if someone harms or interferes with my service dog in Montana?

Montana treats it as a specific offense under Mont. Code Ann. § 45-8-227: Misdemeanor, fine up to $1,000, for harassing, interfering with, or negligently injuring/killing a service animal; restitution under § 45-8-229. Report it to local police, and keep vet bills and witness details.

How do I file a complaint if I'm refused access in Montana?

File with the Montana Human Rights Bureau within 180 days of the incident, or with the U.S. Department of Justice at ADA.gov.

Can I fly with my service dog from Bozeman (BZN)?

Yes. Airlines at Bozeman (BZN) must accept trained service dogs in the cabin free of charge; most ask for the DOT Service Animal Air Transportation Form in advance.

Are service dogs allowed in rental housing in Montana?

Generally yes. Trained service dogs are a reasonable accommodation under the federal Fair Housing Act and Mont. Code Ann. § 70-24-114, so landlords should waive no-pet rules and pet fees, with narrow exceptions such as some small owner-occupied buildings.
