Well, I'm going to use pit bulls as an expample as that's what I'm familiar with.

In order for me to even consider someone a reputable breeder I'd need to see the following:

Health testing. OFA hips, elbows, eyes. Health guarantee.

One litter per year.....max.

For working dogs, I'd like to see working dog titles in obedience, weight pulling, agility. CGC as well. Therapy dog work a plus.

Lastly, I feel that unless you've got a waiting list for at 'least' 7 puppies, you've got no business breeding.

Just a brief synposis of some of the criteria. It may sound harsh, but so is the meaningless deaths of millions of dogs a year, many of them pit bulls.
