Hi all , my puppy Myla is 4 months old and she is starting to get the feathering on the backs of her legs and some on her under side ... I just wondered if her hair looks shorter than the average golden , i know it’s hard to tell at this age what their fur will be full grown. She had the stripe on her back of wavy coarse hair that grew in but everything else is short. Is this normal? Here are some pics
