My 2 year old Shar Pei mix has these stripes on the inside of both her front legs, it’s not different colors rather thicker then thinner fur. At first I thought it was a botched shave job from an iv or something since she had been spayed a couple weeks prior to adopting her. I have had her for 2 months and they are still there with no change! I am mainly just curious what they are- is it a certain breed characteristic, just her unique fur pattern, scars of some sort or maybe something I should be concerned about? Google has said bruising or messed up fur from laying on it but neither are true haha.
