At 24, I had to bury my 20 year old brother after he wrapped his car around a telephone pole.
And I had to shoot my saddle horse a few years back.
Shooting the horse was just as tough to do. But of much shorter duration.
I have had to put down many dogs. Dogs are comparatively easy.
A dog has never carried my nappy ass off a cold frozen mountain in the middle of a freezing wind driven rain storm. A dog has never delivered me safely to camp while I snoozed in the saddle.
