Reinventing the wheel?

To me when the term reinventing the wheel applies when someone is looking to create a new 'Type' of dog, not just cross to different breeds or in some cases classes of dogs. There's nothing wrong with trying something that has not been done before and evaluating the results but when one thinks that by trying one cross, they will know 100% the effectiveness of that cross and then in turn start a line of dogs or create a new breed, that's when problems arise. If a dog consistently produces pork and works for you and you wish to replicate it that's great and. But, just because a dog or in most cases a Breed of dog is physically appealing does not mean it should be crossed. If you have to ask " Do you think X and Y would make a good cross?" Then you probably shouldn't do it. I never saw a great litter originate from a cross that someone was on the fence about. The Guys that have been doing this a long time will always say when two Stellar, world class dogs are bred together "I have high hopes for this litter", because even when both parents are 100% proven and are 4 generations or more down the line of all proven parents, there's still no guarantee. Long Point Short, if it were as easy as A+B=C, there would be a lot less culls around... Most of these trial breedings are done by people who haven't hunted behind enough great dogs to have a clue what they should be duplicating anyway. Just hunt as much as you can. That will answer more questions about what type of dog you're needing than anything else.
