I agree, Cocker Spaniel, the legs are short and stubby, but no real "knot knee" you generally see present in the shorter longer breeds. The head gives no help, as it looks golden, which the coat was sure to give away, so there is no real hint in his face, other than his eyes are awfully far apart, hmm....darn......I have no idea.....good Guess futurevet! Wait, could it be Corgi??? The legs and height kinda match for a Corgi/Golden???
