Remi wasn't overly wrinkly at 12 weeks, but it appears that he's getting more and more wrinkles on his body as he ages (now 5 months). I always thought it was the opposite. Any ideas?
Facial wrinkles become greater as they mature. As pups they have a lot of extra body wrinkles but that tends to fill out as they grow. They are supposed to have 'loose' skin.
