Sounds good XD.
Did you want defect or did you want me to have it?
I name mine:
Girl: Erudia - Erudia looks just as her mother does. Born as a grey pup, she grows into a beauty with a white undercoat and odd black markings splatted though out her pelt. Her eyes are a soft blue, despite often being filled with a haughty air. She know's she is beautiful and is a natural born leader, she'll often do as she pleases and not follow orders. She is the eldest of the pups and very much their bossy elder sibling. She has the defect which is infertility.
Boy: Rilien - Rilien is by far the largest of the litter, with his big paws from the day he was born it is clear he shall be a large brute. He appears much as his father with a deep ebony coat, but has a small point of white upon his chest. He looks to his father as a god, often following him as a shadow. He hangs on every word by his father and hopes one day to have the love his mother and father have together. He is and shall stay a gentle brute, often somewhat shy around those of the female gender. He is the 3rd eldest of the pups, often straying away from the others and sticking close to Aatu.
