Hmmm… seems like we need a 23andMe solution for our pups. How bout we call it K9andme. I can remember most of my pups markings and have 100s of pics to refer to. That said they do change pretty fast. Our pup D’Otto was a split head with a nice dot right in white. It started as a dot and it’s still there! But it’s a bit more of an oval these days.
