If this dog is a stud dog like you say, I presume it's already bred several litters of pups. These are what you want to look at. If these are not making top dogs, don't use the stud, if they are, then use it. Some dogs throw good pups, some don't.
If it was me, I wouldn't want to be the first one to use it.
Now reply and tell me it's not a wind up!
