We rescued this cutie a few months ago. All we know for sure is that he is part Australian Shepherd and his name is Copper. Not sure how much Aussie, or what else he is mixed with. Right now he is about 8 months old and weighs 70-ish lbs. What do you all think he might be mixed with?
2 months ago:
with my in-laws' black lab (Copper is now bigger than the lab)
And these were taken more recently
