This one is in foster and the shelter lists him as being a Shiba Inu mix.  Based on his face, markings, and all that white--- plus the decided lack of Shiba Inus available for "mixing" in this part of the country--- I personally think it may be a Corgi mix.   However, I haven't seen the dog and am just going by the picture.  Sounds like he was a yard dog and would therefore probably do best with an experienced owner.  He's been listed for awhile so it sounds like he might not be the most adoptable dog out there.  Anyone looking to take on a summer project?
