Hello @Alonso,
What specific rules or laws are you after?
In general, service dogs can serve their purpose under similar guidelines as exist in the US. In other words, we don’t have “stricter” rules on Roatan. If anything, you’ll notice the opposite. Either rules don’t exist and or they are not enforced.
I would recommend you contact your local operators, tour guide, or hotel to ask specific questions about your specific situation.
Let me know if we can be more helpful.
