I have stud dogs in miniature Schnauzers, they are mating since 8 months without any troubles. The dog to be offered for stud must be really first class dog fulling the standard and should have some show prices, that the breeders will find him. You should also make eye check - if it's problem by your breed or hips RTG, check the health side.
The system of offering dog for mating is working like any other bussiness - I know the word shouldn't be used in dog breeding, but the way is the same - you must make big advert and have one of the best to be succesfull. I'm showing my dogs all the time to make them more interesting and show them to breeders, we are buing the best bloodlines all over the world to keep interesting stuff. So, if you want to offer the boy for stud you must do a lot for it that he will be used. Because breeders want something special for their girls...
