There is a lot more work standing a dog at stud than you would think.
The bitch owner makes 8 to 10 times the money a stud owner gets for there work when they sell the litter.
A stud with a sought after pedigree does a lot to make a litter saleable.Many sell there puppies on the accomplishments of the stud dog or his pedigree.
I don't think you can compare the work, time or cost involved with breeding and raising a litter vs stud dog services. Big difference! More than 8-10 x's the work and rarely 8-10 x's the money! Don't forget misses either. None of my pet people have sought out puppies based on stud dog accomplishments or pedigree.
