Purebred Minpin puppies for sale

I have four puppies who are pure bred miniature pinschers. They were born on June 26th and are four weeks old. The only female is a light tan with brown and white paws. She's also the smallest one. She's very lovely, but she clearly dominates her brothers. I'm asking $550 for her. Boys come in tan, light brown, and dark brown colors.

All of the puppies are healthy and have been crate and pee pad trained since birth. The vet advised the puppies not to go outside until they had their vaccines. They will be vaccinated, if not moved, by August 10th. The mother weighs 7 pounds, 7 ounces, and the father weighs 8 pounds, 3 ounces.
