That is a Neopolitan mastiff. Agree with Zoom. That's a picture of a very young Mastiff and in picture #2 had he continued foward on the roll as often dogs do when rolling in/on something with an appealing scent, coming shoulder down with all of his weight on the infant, he could have seriously injured the baby. The dog is approx. 80 to 90lbs. and if a male, I agree, is not displaying the affection I think one assumes they see in the picture. It is dangerous for an owner to let a dog that size have physical contact with a baby that size, bottom line.
