Here is my take on breeding and rescue:
If order to be a reputable breeder you have to be willing to take back your own if the situation occurs. That along should be written into a breeders contract. If this was the case with all breeders then there would be no reason from rescue. It does not matter if you are a one time producer of puppies or a puppy mill. If "you" decide to breed and then allow those puppies to leave your care your door should NEVER close to that puppy. If the owner of a puppy the "you" produced decided somewhere along the line that they no longer wanted to care for or were not able to care for "your" puppy then as a breeder you should step in and find a new home for that puppy/dog. If this were to occur there would be no reason for rescues and animal shelters to even exist.
But of course that is not in the real world and there are people producing puppies with no other goal in mind then to make money. Be it puppy mills, bybers, oops litter or whatever you would like to call it~anyone that has a litter of puppies is a breeder. So when all of these unwanted animal need homes due to whatever the circumstance someone needs to step in to help or they will be euthanized.
So then that leaves us with the question of who will take responsibility for the care and possible rehabilitation of the pup that no longer has an owner. Someone who steps forward to rescue then becomes responsible for the care and rehoming process. If it is a breeder I say wonderful for giving back to the animal community.

See yoru rescue through to the end. If there are medical issues treat them. If there are behavior issues address them. Make sure that the dog is spayed/neutered and then find a forever home that will take over their care for the rest of their lives in an appropriate home that fits the needs of the dog. Of course vet checks and references should also be done but that should go without saying to a responsible breeder since they would already be using steps for their own breeding program. It is just that simple. I would agree with Yorkiemother that if a breeder is capable of all of the above then I do not see anything wrong with being involved with a rescue and giving back. I think it is a wonderful way to give back too.
BUT~as we have learned from the Mindy story rescues are not always what they seem and issues may arise and need to be addressed.
PERIOD end of story. There can be no excuses as to why you cannot address the issues and the poorest of the issues is lack of money. When you want to call yourself a rescue and take on the responsibility of any animal there is always financial involvement and the possibility of a long term commitment. Rescues invest hundreds and sometimes thousand of dollars on their dogs. It might take weeks, months and sometimes years to find the very best home for any one pup. Taking on the responsibility of rescues is a huge commitment but emotionally and financially and always seem to the very end without excuses.
So my answer to your question capt_noonie is that yes I do believe that RESPONSIBLE breeders can be involved in rescue it they are willing to spend the time and are financially willing/able to finish with the rescue.
