I think to keep this post down to a minimal size, it might be best for the dog breed's pic to be posted and then wait for a right response before answering, unless you are giving further hints. It wil fill up to page after page in a hurry if every 2-3 posts is, "Nope, not that. nope not that.." ;) And give us 10 or 12 hours to guess the right answer, so that everyone (who doesn't just sit here all day like me ..) has a chance to guess. Just some suggestions.
I kinda thought it looked like a polish lowland sheepdog but the coat color seems to be wrong.
