Bella has super long eyelashes and I keep them, I do trim them a bit when they get too long because they seem to go in all directions and I worry about them getting in her eyes so I cut a bit off when I clip her and they soon grow back - beautiful. Its show thing to cut them off.
I like the neat domed head on Bella my solid black but I like my blue roan looking a scruffy pup, it suits their individual personalities.
