Welcome to the forum Mandy :-)
Documentation needed for the registration of imported dogs:
13b.1) A copy of the official export pedigree as supplied by an organisation in the country of export recognised by the British Kennel Club.
13b.2) In the case of dogs imported from the USA, Canada,
Australia or Denmark, a copy of the registration certificate issued by the kennel club of the country from which the dog is being imported, showing the dog registered in the ownership of the person registering it with the british Kennel Club.
You should be able to register him with the british
Kennel Club if you have this document. Once registered, you would be able to use him 'officially' at stud. You would also need to register him here before you could show him.
We have a few Mal owner/breeders on this forum, so hopefully someone can tell you of the recommended health checks that may be required before you offer him at stud?
NB: if you have any further questions or would like to join this forum, you will need to
register :-)
