Um, well, without knowing his pedigree no one can (or I should say SHOULD) tell you what to breed your dog to.
As an aside...why on earth did you purchase you dog without knowing his background??? How do you NOT know his pedigree--with or without papers in hand???
I'd just like some ideas about what common combination's are among different lines, or if most stick to the same lines because it results in more stable temperaments maybe?
And as for the second part, when I bought the pup I didn't even know there was a such thing as a reputable breeder vs. a byb. This forum has opened my eyes to so much that goes on, and in my area you can open the newspaper year 'round and see "akc german shepherd pups for sale" and not just one ad, but several. It's almost an epidemic. And I've been thinking lately about what a solution could be. The fact is as long as people are buying dogs from these people, it's not going to stop. So fostering and rescuing isn't enough. I believe you can "market" so to speak, to people who don't understand the crisis, and get them to buy from a reputable
breeder (hopefully me in a few years)--but that breeder would have to use the general public's outlets (newspaper, craigslist) and be at their price range (~500). You won't find any reputable breeders taking this approach, which is understandable.
But in the eyes of the purchaser, they would see all these ads and then one would stand out because they have "champion bloodlines, certified hips, health guarantee, etc." So if it's around the same price, why would someone NOT buy from that person? And then of course the main difference would be that a dog that didn't work out, would be returned to the breeder (me) and not taken to a shelter.
Keep in mind this is a thread for gathering info and I'm just thinking through this. No new puppies are in the near future so there is no need to start panicking
