My daughter named both Sirius and Natalie- Sirius was pretty obvious since he is a big black dog, but Natalie was born at Christmas (nativity). Hogan and Pagan both came with their names from the breeder, but we got to pick their registered names. Hogan's litter were named for Elvis songs, so my daughter picked 'PBKs Got My MoJo Workin' (which I have never heard) and Pagan was called Pagan because the breeder like 'P' names- and I kept it because she was 8 months when I got her and seemed mean to change it. I wanted a pretty name that had pagan origin so it fit, and she was born in July, so I chose 'PBKs Summer Solstice'.
