Also, some dogs are more receptive to "affection" than others. Hugging a dog, leaning over him, etc. can be seen as an aggressive position, and many dogs just don't welcome it. I'd not force him to put up with something he's uncomfortable with. Human signs of love don't translate the same to a dog.
