What a great story! I can tell a story about my little hero dog, Bjorn. Bjorn is a 35 Lb. Finnish Spitz (a little hunting dog that looks just like a fox). When my wife was pregnant with my first child, Alec, we were all at the dog run (a fenced in area of NYC parks where dogs are permitted to run free off leash) in Madison Square Park. She was throwing a tennis ball for Bjorn when a full grown Rottweiler (circa 100 lbs. or more) jumped at her to try to take the ball from her hand. My dog, about 1/3 of the Rotty's size, attacked the Rotty to pretect his pregnant mommy. He bit the Rotty's belly, and wouldn't let go. The Rotty couldn't get him off. My friend James, a Vietnam Veteran, who was a dog handler in Vietnam, jumped on the Rotty and pinned him down, and I got my dog off his stomach and out of the dog run. Thankfully neither my dog nor the Rotty was badly injured. Or maybe I should say Thank James (he's is another hero, both in Vietnam and in his day to day life in New York).
I had never imagined my dog, about the size a fox, would be brave enough to attack a dog 3 times his size to protect my wife. I'm glad we never had him fixed, because when he is five, I am bringing him back to the breeder we bought him from, and having him studded out for pick of the litter. As long as I am alive, there will always be a decendant of Bjorn by my side.
