There is no factual data that can be used across the board to prove one way is better than another. Unless you have factual data from everyone that's ever owned dogs on how they do dogs, you will have nothing more than a small sample that can be swayed one way or another.
What's left from a man's yard is usually dictated on how they look at their yard. Percentages pertaining to what? Dogs making it to the box? Dogs actually winning? Dogs being game? Overall percentages can be construed in numerous ways. I know someone that said they've not had a dog quit in 6 years. While that's true, they leave out the fact of picking up dogs at the first sign of trouble. They leave out the fact of picking up dogs, during shows, when they're looking like they're going to pack it in. Maybe the most time they see out of a potential brood dog is 20-30 minutes, and they breed it. Once everything is factored into these individuals and how they do things, the “percentages” are shown in an entirely different light.
I would rather associate with men that could show me something I've missed over time, and I've learned things from both of those individuals. A lot of the men I know that were hard on their dogs gave their dogs all the chances they were willing to give their dogs. Not all dogs, given every chance in the world, are going to amount to anything that we define as a sport. If you do everything you can for a D class dog, it's still a D class dog, and most people don't want D class dogs for any particular reason.
I guess we think about different things when we think of men who only want the best. The men I knew that did that didn't just cull dogs because they didn't start at 16 months old. They weren't idiots. A couple of them usually gave their dogs until the age of 3 to get with the program. It didn't always pan out for them. Some only gave them until the age of 2 to start. Those men knew their dogs. If the dogs didn't meet what it was they wanted, they did what they thought was best for their yard.
You're right about green dogmen. I guess I just don't think about greenhorns much as I generally don't deal with them. I know I've slowed down a lot on my rush to judgement over the years as I think most people do that are successful within dogs. Greenhorns will make every mistake in the book usually unless they have someone that is actually looking out for their best interest and their dog's best interest.
Agree
The thing about trying to factor in how dogs win is actually seeing what they win over. This is just how I see it. I've seen many dogs win over 3 subpar and average dogs in my day, but those dogs are still Champions. It's not the dog's fault his opponent wasn't up to snuff. He did his job as he was supposed to do. There are ton of people who show a ton of dogs because they simply want to show dogs. That's what they want. And if the dog looks good in a few rolls against some dogs, then they take their chances and hope for the best. A lot of times, they're simply showing average dogs. That is how a lot of shows are done, won, and lost. The percentages are high for these kennels until they meet someone who actually brings a match quality dog to a match and not just some dog they want to show. All competition is not created equally, and to me, that's the crux of the entire percentage aspect.
If every dog that was shown would meet an equal opponent, then I guess percentages would mean more to me than they do. While it's nice to hear that a dog, or dogs, that you bred won, it simply doesn't mean that much to me unless the man that won REALLY knows what a quality dog is, and that man feels like he beat a quality dog and not just some average dog someone wanted to show.
