Mutts nuts worry

[some bloke 60]

We are not 'dog' people. I'm looking after an approximately 10 month old Papillon puppy that my son bought before he got a job working away. I'm told Papillons are related to terriers so thought  this might be a place to ask some advice, please forgive me if this is in the wrong section. 

The dog likes to sleep on his back with legs akimbo and we can't help but notice this marking because his underside skin colour is otherwise all pink. He has a small amount of similar colour near his nose if that makes any difference. Should we be worried about this?
