What do I do if my dog breed is not listed?

I have 3 dogs--- all are Omani Wadi dogs. They are not any of the breeds listed. I had their DNA done, and the DNA came back for all of them between 92-96 percent "unknown". Wadi dogs are said to be a mixture of the original village dogs/feral dogs of Oman with some random DNA of dogs that have been left behind by various expats. In the UAE and Saudi Arabia, they are known as Desert dogs. I can't bring myself to check a breed that I know is not representative of my dog, I can't identify them as Omani Wadi dogs, and I can't leave the field blank. How do I get around this?
