She's so pretty
Both of my girls HATE HATE HATE being brushed or groomed in any way

So they are both kept in very short puppy cuts. I have them done every three weeks. They do trim the hair on their noses, but it's not really an issue since it's done often. If they weren't so difficult I'd love to let their hair grow out. They wear PJ's every night though, since my DH works outside in the heat all day, he likes it at 68 degrees in here at night
You could maybe just trim her belly and under her arms shorter so she could still wear clothes and maybe that would help with the knots, I dunno
Good luck whatever you decide. She'll be cute no matter what
