I am thinking $200 for a stud fee, as Yorkie litters are so small it doesn't make sense to do the traditional "pick of the litter" deal. I would consider selling to the right person, but would have to think about a price.
George is 4 years old, in the five pound range, and has a wonderful temperament. He's always been very healthy and is not a barker, except when someone's at the door.
He's sired three litters of puppies by my female with good luck. I am no longer breeding him with my female due to her age.
In the pic with two dogs, he's facing the camera (taken this summer), playing with a friend, and the puppy pic is one of the pups from their last litter.
