Some terms dog breeders use

Breeder Champion Lines
This means that there is a least one champion somewhere in the pedigree. Virtually all-purebred dogs (and a lot of mixed breeds) have champions somewhere in their pedigree. Though you may have to go back 20 generations to find one.

Champion Sired
This means that the father is a breed conformation champion. The title of Champion does not guarantee health and is not an alternative to genetic testing. Remember also that the sire is only half the pedigree. The same rules apply to the Champion dam.

Obedience- titled Parents
This means that the parents have completed the requirements for an obedience title. Although it indicates that the parents are probably well socialized, it is no indication of quality and genetic soundness. Advanced titles such as Companion Dog Excellent (CDX), Utility Dog (UD), and Obedience Trial Champion (O.T.Ch.) can be good indicators of stable temperaments and stamina. It also indicates a breeder who spends a lot of time with his dogs.

Experienced Breeder
This only means the breeder has done a lot of breeding. But it is not clear what kind of breeding has been done.

Reputable Breeder
Again, this doesn’t mean much unless you know them well.
