I don't think it's okay just to breed a dog because it is titled or because it's a Champion.
Look at some examples of breeders I know:
Breeder #1:
Has 10 champions.
Titles on some of her dogs include: CD, CGN, TG-N, TN-N, CGC, RN, CL1-R, CL1-H, CL1-S, PCD, TT, AGX, SMADC, MADC, NGC, TG-N, WV-N, AGI, ADC,
If someone is focused on titles they may think she is a good breeder. This breeder bred two dogs that she knew both carried the gene for cleft palates. Four of the puppies were born with cleft palates. She let them starve to death. This breeder used to work where I am. She was fired because she was incredibly abusive to the dogs. In agility class she would pinch her dogs when she thought no one was looking. The only reason 8 of the 10 dogs she has got their CH is because she enters lots of her dogs in one show and pins them up against eachother so that if one of her dogs wins, which it usually did because she was the only one with the breed, it would get more points. Her dogs are ugly as hell. In one show, a judge actually said "none of these dogs deserve ribbons" and excused them all from the ring. In another show, the judge asked why there were 2 of the same breed in the group ring -- well, one was the right breed -- he mistook her dog for that breed too!
Breeder #2
All six of her dogs are CH, some both Am/Can CH.
Titles include: CD, CGC, HIC, BPD, VCX, ROMX, HT, PT, TT
Titles look awesome. All of her dogs are champions. 3 of her 6 dogs also have collie eye anomoly. Some of them are slightly micropthalmic (not enough for the judges to notice, but who knows what they produce). 4 of her dogs are MDR1 carriers. She was recently disqualified from a show for kicking one of her clients' dogs down a hill. I've heard horror stories (and experienced one myself with my own dog and this breeder) of dogs going to a show with her and then never being showable again. I've talked to one person who says they've seen her kick a dog in the ribs, and another person who says they saw her throw a client dog down and hit it repeatedly for barking.
I can name a dozen more cases like these.
Now, I also don't find it okay to breed just for pets.
Breeder #1:
Bred their goldens as "pets." Because the dogs were just pets, they didn't research the pedigree. Turns out the dogs were full-siblings. Every puppy in that litter was COMPLETELY INSANE. These were golden retrievers that would sooner rip your face off than look at you. I believe only one of the puppies wasn't put to sleep.
Breeder #2:
Bred their chi/pom mix and their chihuahua. They just wanted to make cute little pets. I know two of the dogs from this litter. One of them is getting surgery to fix his luxating pattellas. The other has some disease the vets can't even figure out.
In other words, I don't think that people should be breeding for show, and I don't think they should be breeding for pets. They should be breeding for the ALL-AROUND DOG. Breed for show, breed for pet, breed for health and temperment and working ability and soundness of body and mind. Love your dogs, take care of your dogs, call your breeding program a hobby but treat it like it's your life and your passion. People focus too much one one factor. "Well this breeder titles their dogs." "This breeder health certifies." "All of this breeder's dogs are champions." Look at the whole picture....
