can any one tell me how much i can expect to pay for a single mating by a german shepherd stud dog of good quality?

Hi Guest, this is one of those 'how long is a piece of string' questions.
Stud arrangements vary so much, some ask for approx the price of a puppy, some say £100 plus £50 for each puppy born. Then there's those that will waive the fee if only one or two puppies are born.Then some will ask for a pick of litter in leiu of a fee.

Your best bet is to make your choice of stud dog, and then ask his owner what his fees or conditions are.
