If it's all up and down the belly I wouldn't worry about it, it's just the very beginning of the shedding process. It can be anywhere from light peach to pink and will darken for about a week, along with the skin subsequently getting darker and the eyes turning cloudy. If it's a youngster shedding regularly every month it means he's healthy and growing

Great. He's almost 8 months old. He's eating like a pig and getting big fast. And it's over his entire belly.
