This section is informational and is not legal advice. Anyone with a specific concern should confirm the current rules with their local authority.
There is no breed-specific legislation targeting the Dutch. Like other domestic rabbits, it is regulated, where it is regulated at all, as a rabbit rather than as a particular breed, and lop or marked patterns make no legal difference.
The rules that matter are about rabbits in general and are often geographic. The most striking example is the outright restriction of pet rabbits in some jurisdictions for ecological reasons, most notably the Australian state of Queensland, where keeping pet rabbits is generally prohibited regardless of breed.
A prospective owner's research should therefore focus on whether and how pet rabbits are permitted and classified in their specific location, not on anything unique to the Dutch.
