As Karen said, the rescues group for both BCs and Aussies are staffed very committed people! Volunteers who love the breeds and know how to work with them.

Breeding for 'fun' is just nuts. A reputable breeder is going to do extensive genelogical work and have testing done on both sire and dam to ensure no genetic defects are present. A reputable breeder is working to improve the breed, and is actively involved with the breed group - either in conformation, or Agility, field trials, etc. A reputable breeder provides a minimum 2 years health guarantee and will insist that ANY puppy placed be returned to him if the dog cannot be cared for, at any time during the life of the dog. The reputable breeder has all this in the contract, and makes sure the contract is enforced! I've a FB friend enforcing a contract with a bichon puppy she placed in Belgium, and the people apparently got rid of the dog; she has hired legal counsel and is getting the dog BACK.

Are you committed and prepared to do all of this? Any reputable breeder will tell you, breeding is not a money maker; it is a big financial hole, and they are in it for the love of the breed and to better the breed. NOT 'for fun.'
