She wrote, "Who called my little son a fatty!  My son is just chubby!!  Did he gain..a bit..because it's winter?  Photo by Hwang mommy."  The picture included one large one of Sunny with the dog and three small ones of just the dog on the side.  The dog looks very white and so fluffy (that I could die!) as it winks and even closes its eyes sleepily.
