why wary if they own both or is it be wary if they are both young dogs ??
I can see what he is saying, it can work two ways, first, they have worked out what they want in the future, got a dog and bitch in, tested and tested them to satisfaction and then bred what they want.
But also when someone has both sire and damn and they aren't that old etc, you get the impression they may just be breeding a litter because they can, and doing it the way thats least hassle rather than the way that will produce top dogs.
How many folk are lucky enough to have a great bitch and a great dog . . .
