All About Fat Boy

First things first, fat boy is my 3 month old puppy.  He was born on July 10th. Honestly, my family didn't know my dog (the mom) was pregnant until she was having the actual babies.  She only had two dogs.  He had one brother but he died two days after he was born.  Fat Boy is very small but very fluffy.  His hair has gotten so long it hangs in his face so you can't see his eyeballs.  His fur is white but he has some light brown spots on him while his ears are black, kind of gray.  He is half Maltese and half Pomeranian.  He gets the white fur from his mom, the light brown fur from his dad, but I have no idea where the black fur comes from?  The first week after Fat Boy was born all he did was eat and sleep. That's why I named him fat boy. Trust me he got so big the first week it was crazy.
