All I know is that your doggie is sweet and gorgeous, which is all I really need to know.
If you really want to learn your dog’s background, you can have a DNA test done for about $80. There are plenty of labs to be found online, at competitive prices. The merchant will likely ask for a photo, but it’s best not to provide one; make the test lab do its job. I had my last doggie’s DNA tested, and the lab nailed it without any help from a picture.
