Yall talking about great dogs over here.....and Im just trying to get a good one?!

In all honesty. Ive had some very, very, very good dogs. BUT
Ive yet to have my great dog. The closest thing I had got crippled up young. Still was a very very good dog.
That said Ive only seen 1-2 truly great dogs. Of those ones I have seen.....when bred always seemed to produce below average dogs, even when bred to good dogs. Dont know if the expectation was too high on the offspring or discouragement from the owners? But it is funny how that works sometimes. Do yall see the same?
