Right now I remember Leon, my Leon. My old man found it full of parasites under our car. It turned out that the dog was in the street and it was cold, it stayed under the car because of heat and my old man when leaving the house he heard a howl of pain, it was him. A collie's half-breed puppy. That dog was the most faithful, loving and peaceful dog I ever met in my life. He died of cancer one night while I was in college, and my parents waited until I came back to bury him. Today I do not have a dog, my parents have 3 poodles toy but do not even reach the ankles of such a dog. Once a Pitbull wanted to kill him and couldn't because of his thick wool around his neck, with my old man we fainted the murdering dog with an old steel inflator hitting him on the back of his neck. The gratitude of that dog was and is memorable, no matter where he followed me.
By the way thanks for save that puppie. The world is a bit better with actions like yours.
