Mixed-breed dog registration vs. breed variety documentation
https://blast-wiki.win/index.php/Mixed-breed_dog_registration_vs._breed_variety_documentation
When registering your mixed-breed dog, you might notice the form asks for a breed guess, but breed variety documentation is for purebreds with known lineage. I had to describe my pup as a 'terrier mix' because his exact ancestry is a mystery, while breed documentation tracks predictable traits. It's a small distinction that makes a big difference for owners like me.
