Good job by the both of you. There have been many a dog voluntarily lay down his life for his owner, but I'm glad it didn't come to that this time.
Folks who aren't pet lovers just can't grasp that bond .. a beloved pet is another child to us. What a Super Sam, the angel .. his instincts kicked in like yours did .. totally breathtaking. He sure does he love you. You've both lived through something none of us ever will, and both deserve medals. Thank you so much for sharing this .. I hope both your wounds heal well and quickly. Maybe .. stay out of the woods for awhile, and keep us posted on the movie ;).
