(17)In order to simplify the conditions for the non-commercial movement of pet animals of the species listed in Part A of Annex I between Member States of equivalent favourable status with regard to rabies, this Regulation should also provide for the possibility to derogate from the anti-rabies vaccination requirement. Such a possibility should be available upon submission of a joint application by the Member States interested. Such a derogation should be based on validated scientific information and be applied proportionately to the risk to public or animal health associated with the non-commercial movement of those animals likely to be affected by rabies. Member States or parts thereof benefiting from such a derogation should be listed in an implementing act to be adopted pursuant to this Regulation.
