Even with this I still believe that all dogs are part of the same species because when looking into dog DNA, there is usually one shared gene causing the physical size differences but the rest of the DNA very similar. This means that all dogs are closely genetically the same other than physical traits. Wed, 20 Feb 2019 14:55:32 -0500
