From Chase: Guiness is a German Shepherd Dog Rottweiler mix. I am not sure exactly what the main breeds are of my dog. He has distinguishing features of many dogs. Hoping that someone else would have some input! He’s a great dog, very very well behaved, and easy to train. Very loyal to the family, and works well with dogs, and absolutely loves children.
From AllMutt: I can see him being primarily German Shepherd and Rottweiler based on colors and the ears that are kind of in between the two breeds. The white patch makes me wonder if there is a bit of Pit or Boxer in there.
