It's actually not all that uncommon. If she had a small cut from something before, a fly will use open wounds to lay its larvae in (I work in a hospital and have seen this in people...yup...gross). There are SOME flied that are biting flies which will bite and create and small opening to lay their eggs in.
Totally gross, but not unheard of! I was thinking it was an abscess, as I have had all too many experiences with this (my husbands lab, who lives with his parents, had one for a long time and we couldn't get it to heal).
Good thing you figured out what it was! Just keep the area VERY clean and keep the hair around it shaved. If hair or dirt gets in there while its closing up, it COULD form an abscess...which isn't fun.
