A story came up today that needs to go on one of the dog threads. There are numerous threads to discuss particular losses (a couple of my own dogs have been memorialized at Mudcat) but this is a good general look at how they become a real part of our families, and why we mourn their loss. Here is an excerpt:

Why Losing A Dog Can Be Harder Than Losing A Relative Or Friend

An interspecies bond like no other

What is it about dogs, exactly, that make humans bond so closely with them?

For starters, dogs have had to adapt to living with humans over the past 10,000 years. And they’ve done it very well: They’re the only animal to have evolved specifically to be our companions and friends. Anthropologist Brian Hare has developed the “Domestication Hypothesis” to explain how dogs morphed from their grey wolf ancestors into the socially skilled animals that we now interact with in very much the same way as we interact with other people.

Perhaps one reason our relationships with dogs can be even more satisfying than our human relationships is that dogs provide us with such unconditional, uncritical positive feedback. (As the old saying goes, “May I become the kind of person that my dog thinks I already am.”)

This is no accident. They have been selectively bred through generations to pay attention to people, and MRI scans show that dog brains respond to praise from their owners just as strongly as they do to food (and for some dogs, praise is an even more effective incentive than food). Dogs recognize people and can learn to interpret human emotional states from facial expression alone. Scientific studies also indicate that dogs can understand human intentions, try to help their owners and even avoid people who don’t cooperate with their owners or treat them well.

Not surprisingly, humans respond positively to such unrequited affection, assistance and loyalty. Just looking at dogs can make people smile. Dog owners score higher on measures of well-being and they are happier, on average, than people who own cats or no pets at all.
