Has he been BAER tested with a certificate to prove he has bilateral hearing? No dalmatian should be bred from without this proof. To be used at stud he'll need to be a good example of his breed; there are plenty of Champions at stud, so he'll have to have something good to offer the breed. The best way to find this out is to show him - if he does well, then bitch owners will ask if they can use him. If he doesn't do well, they won't.
Remember, using him at stud could change his nature from the soft, soppy boy he is now to an overly masculine, possibly dog-aggressive animal - although this doesn't always happen. You will also have lifelong moral responsibility for any puppies he sires, maybe having to take them into your home if the new owners can't keep them.
Also, have a read of the first post on the Breeding forum of this site.
