discoloured nose?

Logans been getting paler in the face in the past few months, but last night i noticed a white patch on the side of his snout and his nose looked very pink. I was worried he'd perhaps rubbed his nose, and some of his fur away. Having had a better look in daylight today there's no hair loss, the hairs have just gone white. His nose has pink patches like some dogs have, like where white markings run over. Is it likely that this is the case? He does appear to have white patches on his back like his mum, but would he be getting new markings at 2 years old? I don't think i've even seen any hoggies with patches on their faces?


Afraid pic isnt very clear he didnt want to look at the camera, but you can just see the pale pink on the tip of his nose, and how pale his face is now.

they can lose pigment as they get older - one of mine is the same - he's got an odd two tone nose and the pigment is slowly going all together - he will end up with a pink nose at the rate he's going
