John is a great trainer and I'm sure your dog will pull out a junior title but what people are going to want to know is at this point in the dogs career what is it that makes you think his genes are worthy of passing on? At this point we don't know if the dog has good hips, elbows, has PRA, CNM, EIC. We most likely don't even know at this point if the dog can count past two.
You will not have the answer to most of these questions until the dog is over two years old. By that time you should be able to answer the question "what qualities does this dog have that I want to pass on to future progeny that better the breed?"
Black males are a dime a dozen. Unless you have an HRCH, MH, QAA, or have made the derby list by that time you are going to be limited in who will want to breed to you. That all takes a time and monetary commitment.
On top of that the pedigree behind him had better be good unless he wins a national.
Not trying to be mean but this is why people are shocked you are putting this out there at this time.
Good luck with your pup.
