You can't analyze a person's behavior, especial their emotional behavior, without including cultural context. Society does not appreciate people leaving toddlers home alone, but they do not care if you do so with a puppy. That alone is enough to make the matter of "dog care" irrelevant in assessing someone's feelings on the matter.

Yes, but the poster loves his dog more than any human has ever loved their child. He does not merely conform to societal norms with such love.

Clearly such an exceptional dog-lover won't conform to your expectations about how that love manifests, either.
