XL Bully owners in Jersey need a licence to travel in and out of the island with their dogs.
The law changes on Saturday, 24 February, and requires people with a dog of that type to apply for an export licence from the Animal Health and Welfare team through rva@gov.je.
Owners will also need written confirmation that their entry with an XL Bully dog will be accepted by the countries they are travelling to or through.
The update in legislation comes after the UK made it illegal to sell, abandon, give away or breed XL Bullies in England and Wales.
UK Ministers also made it illegal to have a dog of that type in public without a lead or muzzle.
Owners who think their dog could be confused with an XL Bully should also contact the Animal Health and Welfare team on the email above.
Jurors have heard the 999 call made by Haut Du Mont resident Louisa De Almeida, reporting the smell of gas inside her flat, hours before the explosion that killed her and nine others in December 2022.
The supervising engineer of gas works that led to a fatal explosion at Haut du Mont was distracted when he attended the flats to check valves were closed, Jersey's Royal Court has been told.
A jury has heard claims the gas work undertaken in the area around Haut Du Mont on the day before a fatal explosion four years ago was rushed, based on 'guesswork', and 'sloppy'.
