So in my quest for knowledge, I have been studying every pedigree I come across. In 90% of the WL pedigrees you see the same "key players". So if all these dogs have the same dogs behind them, what makes one litter solid and another weak? I would guess it would reflect more on the non big name dogs. But then how do you know by looking at the pedigree if its a solid dog or not? It's mostly the females that it's hard to get info on. Like they say all good bitches belong in the whelping room. Well then how do you know she's good by looking at paper? I hope what I'm asking makes sense. Thanks in advance.
