It seems as if touch doesn’t merely increase your good feelings, but it also decreases your bad feelings.
For many years, researchers believed that the nerves of our skin could recognize just four kinds of stimulation: touch, heat, pain and itch. But there is growing evidence that cutaneous senses include another one that conveys information not just about touch, but about the pleasant properties of touch.
Animals that are social by nature, such as many birds and mammals, have areas that can’t be reached by their own design and must be addressed either by rubbing against objects or by grooming by others. These areas — largely the head and neck — appear to be endowed with extra nerves that feel good when stimulated.
Among the most remarkable animal stories are those involving friendships where we might not expect them. A friendship between man and dog is not surprising — after all, a dog is man’s best friend. Nor is it surprising to find a friendship between two dogs — or two men. We expect intraspecies friendships (friendships within the same species) .
But then we don’t. A friendship between two fish would surprise us, or between two invertebrates, two amphibians, or two reptiles. And we are surprised when we come upon apparent friendships between two very different species, such as cat and bird or duck and owl.
One of the most common social behaviors is allogrooming (also known as mutual grooming). It is expressed by the lateral parallel body position of two horses that allows for nibbling along the back or withers of each horse. While this behavior can be considered grooming, it is also thought to facilitate pair-bonding and dominance structure between band mates
There is one thing that all of our husbandry can’t change: horses love each other, just as elephants love each other and deer love each other. Horses can’t get enough of each other. They would be close together in a herd every minute of the day, given a choice. I was especially struck by this in driving across Wyoming, where a pasture can often be 100 acres or more. Survey such a pasture, and find who lives there: a half dozen or so horses. And where are they? Jammed together in one place or another, so close that one tail can swat the flies on a friend’s body. Horses never live alone in the wild, and should never be forced to live alone in captivity.
