I have been breeding working dogs for over 40 yrs.
There is not a single person on here with more hands on experience.
I have turned a few dogs into more than one family strain of dogs.
More than most who have wrote books or been written about.
Those that haven't the 16 generation hands on experience as I have.
I have bred over 100 litters in my time & went thru all of them.
Most these days don't even have a clue about Punnett squares or Gregor Mandal.
It does not take 18 months -2 yrs to know a dog .
If you have hands on experienece with each generation for more than 4 generations you should know it like the back of your hand.
Selling the most dogs to the public & actually working the most dogs you feed & breed or two complete different things.
That's what pedigree shows & nothing else.
There are guarentees when if you get on the level oh having hands on with 4-8 strait generations or more. You just have to get on that level.
If someone has that many & still doesn't have a clue about how they will turn out than they are just cluelss period.
If you have actual concern & want actual facts & results then here is you true answer.
Personal hands on experience & can tell you what is what before even breeding pair with more hands on experience per dog ,per generation than any one on here.
