No the OP doesn't 'know' anything more than what they did before. Those tests are notorious for being wrong. Somewhere I have a post all about it WHY they can't be counted on. It has to do with the fact that there are NO genes that are specific to a breed, and the genes they are testing are the non coding 'junk' DNA and its all a numbers game to try to 'guess' what your dog is.
These are good for a laugh, but not really anything more.
