In short, the unknown percentage of your dog’s ancestry might not be just one big section of mystery in their DNA… but many, many small sections of mysterious DNA that add up! It’s not clear what or how many breeds may exist in the unknown.
One way we can find out is when an owner gives us feedback that they know their dog is a certain breed not yet in our reference panel. These dogs come up with a high percentage of unknown, or a closely related breed. We’ve seen this with American Pit Bull Terriers: high percentage unknown, high percentage Staffordshire. This was a good sign that we needed to add APBTs to our breed reference panel.
We expect to minimize much of the unknown percentage as we improve our reference panel by adding more breeds.
