There are other diseases, i.e. Perthes, where it is not yet proved whether this is hereditary, and also digestive problems. It is always good to see the mother of the pup and make sure the puppy is assertive, bright eyed, and comes to you wagging his tail. Look also for a good, firm body and ask about the worming programme, and injections. If you wish to buy a poodle to show I always advise anyone to go around the shows first of all to see them in action, to speak to breeders, get advice, and watch how they are shown, how they are trimmed - as the trimming fashion changes a good deal. This is only my personal opinion.
Poodles come in a variety of colours - black, silver, apricot, white, cream and blue.
