Question: do SIDE OF THE NECK tattoos fade easier due to daily movement? and also a question about shading

im thinking of getting a little one square dog paw tattoo NOT center of my neck, but a bit higher, a few inches below my ear.

do they wear down quick because the skin moves a lot whenever you turn your head?

i was thinking of just getting it fully black due to this potential thing.

even tho a bit shading in there would make it more aesthetic
