I just read a lovely article about old dogs that should be shared. Please read it.
To those words can add only one thought. Weingarten mentions people who "seem unmoved by the deaths of tens of thousands through war or natural disaster will nonetheless grieve inconsolably over the loss of the family dog." He goes on to suggest a reason for this seemingly odd behavior. And I agree with him, but I want to add a second reason.
We all do this to some degree, though not necessarily over the family pet. The loss of someone close to us - a spouse or child, a close friend or relative - affects us much more than the deaths of those farther away. It's simple human nature, and those of us who are close to our dogs have simply included them in the circle of companions we'll miss more intensely when they're gone.
I've got some familiarity with old dogs, and they often have a certain accepting dignity about them. I hope I can show some of that as I age.
