I have a Norwich Sealyham terrier mix so I wanted to test this app. I know I put in the info very accurately and neither the Sealyham or Norwich terrier was on the list of breeds. It said it was a cross between chihuahua and a couple other breeds that were way off. I even tried it for the sister and different breeds came up for that one. However it is accurate for more common breeds such as lab and retriever.
