As kita says, anytime after twelve months is fine for hip scoring. Unless you have a very laid back dog, it is difficult to get them to lie still enough without knocking them out, but if you have a particularly quiet Malinois (a contradition in terms!)
you might get away with sedation. I will enquire about vets in your area who do them without anaesthetic and let you know.
As for eyes, they should be done annually (usually, depending on conditions prevalent in your breed), and your nearest specialist is Ian Mason, Seadown Vet Hospital, Frost Lane, Hythe, SO45 3NG tel 02380 842237. Details of other eye testing sessions can be found in either of the weekly dog papers, Our Dogs or Dog World, and they are often held at shows, so again I will look out for any in your area and let you know.
Obviously if you are planning on breeding, then try to get her eye tested as near as possible before mating as you can, to ensure the most up to date information.
