Google - what do you think about linebreeding in dobermanns? (1rst cousin x 1rst cousin)?

I would not breed any dog with related other dogs! For starters this could cause issues with the puppies. Secondly, if you breed from the same family your puppies will not have good backfgrounds. For example I breed AKC german shorthiared and on both sides the parents of the puppies come from different families with different accomplishments this adds more qualification to your new puppies. Hope this helps!!
