I also thought terrier as it looks like they have a slightly wirey hair to them. And also ridgeback if the hair stands up if it is just a little darker in color it may just be the shep. It seems part shep. in the face structure and kinda terrier in the face too. The ears might be part terrier, ridgeback or possibly lab. The color looks like ridgeback or lab (although some sheps are more tan and if it has a slight black mark on the back that might also come from shep)But the ears might stand up more as the dog ages. Isnt it always fun to keep guessing mixes?

DEFFINETELY CUTE!!! Are you going to find hoes or keep them?
