I've always been a little skeptical of the DNA testing for dogs - a few years back someone did a test where they sent samples to 3 different laboratories and got 3 different analyses. Might be more accurate now, but we're keeping the dog anyway, and she has been spayed, so not sure how important it is to have a named breed or mix.
People ask and I tell them she's an 'I Don't Know', or a 'Good Dog'. People like to guess, so afterwards I go on-line and look up all these species that I never heard of to compare photos.
A family friend is involved in dog rescue and fostering - every dog she has is listed as a 'Sweet Girl' or a 'Sweet Boy'. Might be new breeds?
