I'm assuming she's KC registered and BAER tested normal? Is she a very good example of the breed - has she done well in shows or otherwise been independently assessed? I'm sure you know that only about 10% of pedigree dogs are of suitable breeding quality, and dalmatians are especially difficult!
Her breeder (if knowledgeable) would be the best person to advise on which stud dog to use and which lines to avoid, because some bloodlines, when combined, are a disaster! :(
