The best thing you could do is telephone nearest Breed Club Secretary. As you don't say where abouts you live I can't say which one will be the nearest but all the contacts can be found
Here. Also have a look
Here for breed specific help and advice. If it's a show type cocker you are looking to add to your family you'll find it much easier to locate a black than a solid chocolate/liver - this colour is seen more often in working lines. You may also find that as we get closer to Christmas, there are less puppies available from reputable sources - a well-bred puppy is worth the wait, though :-)
HTH :-)
