My Dog Meets His Long Lost Brother! Can Dogs Tell They re Related??

Ok ok, he s not long lost he just hasn t seen him since 8 weeks old! You can tell the two apart if you have a keen eye but they are so identical! They were stuck to each other s side while playing and so happy to see each other. Do you think they know they are related or dogs can tell it s their sibling, father, mother?? Let us know your thoughts below, I m intrigued to see what the majority is.... x
