Poor little Bango, and his mommy. I was luckier than that, I had a Chihuahua once to be attacked by a German Shepard, it grabbed my little Bingo and ran off with her, my husband tried to catch it as it ran by him with my Bingo between its teeth and he missed. Well when it run by me I just jumped on top of the dog and it let go of my Chihuahua. Believe it or not, I was trying to choke the dog to death, I was so angry I didn't even know what I was doing. Anyway my husband told me to get off the dog that I couldn't kill it like that. That dog never came back to my place, and my Bingo lived and wasn't hurt.
That had to be dreadful to witness, that dog killing a defenseless little puppy. I hope they put it down too. That really makes me angry to hear such a terrible thing. My heart just goes out to Sara, she has to be really hurting.
