2 Pomchi puppies 12 weeks old

2 puppies, one girl is black and white and the other boy is brown and white, they will be small, about 8-10lbs, and they are half pomeranian and half chihuahua. I would like to sell them together because they are very attached to each other and because they are brothers and sisters. They are 12 weeks old, have had their first shots, and are in excellent health. They are very intelligent and loving, and have been partially potty trained to go outside. They are priced at $500 for both.
