From the 1 January 2012 the EU rules regarding pet travel from the UK to Ireland changed. However, pet owners travelling should not experience any changes on the ground. Full details can be found at defra.gov.uk
The following breeds have restrictions that you need to comply with:
and any other dog of the type commonly known as a Ban Dog (or Bandog) and every other strain or cross of every breed or type of all of these dogs.
In public places all of the above dog breeds must be kept on a sufficiently strong chain or leash, not exceeding two metres in length, by a person over the age of sixteen years who is capable of controlling them, they must be securely muzzled, and at all times wear a collar bearing the name and address of the owner.
