I couldn't find your picture so I'm literally speculating, but it could be dermatitis mange. This mange is caused by mites, which all dogs get from their mothers. Not infectious to other dogs or humans. You can see the mites under a microscope. If it is dermatitis mange, I'd ignore it unless it starts getting out of control since it's not harmful.
I don't think you'd need a groomer unless your baby is seriously resistant to nail trimming. As others have mentioned, they shed a couple of times a year. Usually not a big deal.
