I have suffered more grief over the loss of some of my dogs than over some of the people I've known.  That isn't right, I know, but I can't help it.  I was particularly fond of two who were brother and sister from the same litter.  Half Catahoula, one quarter beagle and one quarter blue-heeler.  Aggressive when they needed to be, extremely protective of my two children.  While they roamed outside quite a bit, we kept them cleaned up and allowed them to sleep in the house.  Both would curl up around our feet or sleep pressed against our backs.
We lost the female to a hit-and-run driver.  The male came down with cancer and had to be put to sleep.  I cried for days.
