Oh my gosh look at those brown eyes and I love his markings!!! I agree with everyone else, adorable, sweet, heart melter!!!!!!!!!!
The second photo is just priceless. I am not sure about his breed(s). He could have Lab. See if he wants to constantly carry something in his mouth and also retrieve. Also I thought of maybe the swiss mountain dog or great swiss mountain dog, I know there are two different ones but the one with the shorter coat. Look at this photo:
