Dogs are obviously not humans, but one possible explanation for this apparently irrational behavior could be our ambiguous posture towards them. In many respects dogs are better than people - they are reliable in their behavior and their love, and their soft coat is pleasant to stroke and touch. We can confide in them when worried and know that they will hold their silence. However, we can also cease to treat them as human beings at will and describe them as curs or in other derogatory terms.
For the most part, the human view of dogs prevails, and it is interesting to consider some recent findings of a survey of American dog owners. In more than half of the cases, the dog slept at least sometimes on the bed of a family member, and nearly all owners had a photograph of their dog, usually in a pose which indicated a close relationship, with the owner touching the animal and with the heads of the two close together, as in a parent and child relationship.
