Pug with wavy skin?

[Mairead]

I have just seen a pet pug with what I would describe as wavy skin. When I said I had never seen that on a pug before, they said "Maybe a mix?" She looks purebred but could she have a dash of Shar Pei?

They bought her at age one year. She wasn't overweight.

Is this just a variation or is it an indication of a health issue?

She looks to have had a litter, not recently, nipples prominent.

Most likely a mix and some girls have large nipples whether they have had a litter or not. Different breed but you couldn't tell my girls had had even a heat, let alone a litter.

It could be a variation, or there could be something else in there. I’ve seen a lot of pugs over the years with excess skin folds on their face and down the neck and top of shoulders. 
 

Hair and skin folds often coincide too. One of my pugs had a huge mane, like a lion, around his neck.

This was parallel lines all along the back to the tail.

Breeders breed specifically for deep folds on the face. It stands to reason this may show all over the body. It shows easily on the face because of the flattened features.

Could simply be wavy coat &  Pugs can have shaded coat colouring so can look wavy but arent .
Easiest way to really tell would be wet after a bath
