True, hind-sight is 20/20. The dog had been harrassing my own livestock and pets. Also, any friends that came over often had to watch out for the stray.
I never did see a collar on it. There are several stray dogs in the area, but I did check with some of the immediate neighbors and none of them claimed it. I felt it was necessary to remove it from the property.
True, I did go against several important ethical and moral beliefs that myself and many other follow:
1. only shoot when you are sure of your background
2. shoot to kill or don't shoot at all
3. come prepared for a second shot if you screw up the first one
etc. etc. etc.
If the owner of the dog reads my posts, I wish you to know that if it survived and returns to you, I'm sorry I wounded your dog.. . but you may want to keep it on a chain cause if it bites at my cattle, barks at my kids, or eats one of the chickens (again), I will use a bigger caliber at closer range so that I will know for sure the job is done. (Sorry... for sensitive readers)
I appreciate all of your comments and I will be a little more choosy next time.
ps. Since my last post I bought a box of 45 grain Horady SP and I'm pricing a scope with illuminated recticle.
