This was very interesting in light of the results I received from Embarks 2018 test of Ottos DNA. Its results were very similarwith a notable exception. Embark identified Ottos bully breed ancestor as American Pit Bull Terrier, and also indicated that he was more APBT than anything else, as much as 21.2%! This company also found Cattle Dog, German Shepherd, Chow, and Border Collie in Otto, but added some Labrador.
