Are you committed to the puppies for their entire life. In other words, will you take them back no matter what. These are but a few questions which you need to answer before you even consider breeding your jrts. A prospective buyer will want to know the answer to all of the above. Lastly, I urger you to reconsider breeding casually.
Rescue is full of unwanted dogs.
So please unless you are prepared to make a lifetime commitment to the pups, please reconsider.
