Best place to start: The research for a WONDERFUL mentor. The best thing a person can have is a wonderful, RESPONSIBLE mentor.
You want someone who has the thought of the breed on their mind, not just quick $$$$> Someone who does more than just breed, whether it's herding, showing, obedience, agility. Someone who tests their dogs(CERF and Thyroid I believe are problems in Collies, and think they should be OFA'd, but won't bet on that LOL) Someone who researches the bloodlines, pedigrees. Someone who breeds rarely, and not just to 'sell puppies'. Someone who weeds throught the bad people for Collies, and finds the good homes. They sell on S&N, and have a comes back to breeder clause if something should happen and the owner can't keep them.
Stay away from people who
1. Never have pets(all breeders have pets in their normal sized litters)
2. Don't require S&N on pets
3. Trash all other breeders as not having good dogs, only their dogs are good.
4. Constantly has puppies or young adults for sale.
Good luck. . .i know there'll be plenty of good advice thrown your way.
