Service Dog Laws: State vs. Federal – Which One Do You Follow?
When it comes to service dogs, things can get confusing fast. There are federal laws and state laws, and sometimes they don’t say the exact same thing.
At the federal level, the Americans with Disabilities Act (ADA) sets the minimum standard. Under the ADA:
• A service dog is individually trained to perform tasks for a person with a disability.
• Businesses open to the public must allow service dogs.
• Dogs do not have to be registered, certified, or wear special identification.
• Staff may only ask two specific questions if the disability is not obvious.
The ADA applies nationwide and provides a baseline of protection. No state can create a law that gives less access than the ADA allows.
However, individual states can create laws that:
• Add additional protections for handlers
• Address state-level penalties for misrepresentation
• Clarify rules in housing or schools
• Include service dogs in training
If a state law gives more protection than federal law, you can generally rely on the stronger protection. But if a state law conflicts by trying to restrict access in a way that goes against the ADA, federal law prevails.
This is where confusion happens. Some states word things differently, define service animals slightly differently in certain contexts, or have additional requirements in specific settings. That doesn’t override federal access rights — but it can affect how situations play out locally.
The key takeaway:
👉 Federal law sets the floor.
👉 States can raise the ceiling — but not lower the floor.
Understanding both levels helps handlers advocate confidently while staying compliant.

Have you ever encountered a situation where someone quoted “state law” that conflicted with federal service dog law? How did you handle it?
