I would like to say this is cute, and I love pics of babies and animals, but the dog does not look all that gentle around the baby.
Even if in the 2nd pic he's not putting any weight on the baby, the baby is facedown on the blanket. In the last pic, I would like to go "awwwwe", but since I can't see where the baby's legs are, I'm wondering if the dog is pinning him down, placing his leg on the baby's back. If that is the case, he is putting weight on the child.
No matter how much we love our big paws, I know how clumsy Gunther is, besides the fact he thinks he's much smaller than he actually is. I could never leave him somewhat unsupervised around an infant, no matter how gentle I know he is.
