“It’s not the size of the dog in the fight, it’s the size of the fight in the dog.”
That reminds me of a funny story…
We have big dogs, big livestock guardian dogs. One of them, Hagrid the half-giant, was especially large. He could leap up over eight foot fences, down over 12′ cliffs and do repeated back flips over my head as well as throwing a 300 lb pig with one paw. He often would perch on the roof of our shed, 11′ up and then jump down when he wanted to go investigate something. Hagrid was 7′ long from the tip of his nose to the tip of his tail and heavy enough that I stopped trying to weigh him although he still thought he was a lap dog. Hagrid was a big dog by anyone’s definition.
One day a friend of ours came over with his dog – a tiny, yappy ball of fluff that thought it was boss of the whole wide world. On arriving it saw another dog and exerted its full authority – it ran yapping at full volume towards Hagrid who was lying peacefully in the sun watching it.
Hagrid yawned open a mouth full of 42 huge, white teeth set in jaws that were large enough to take that little dog in one easy bite.
The yapper screeched to a hard stop just before falling in. It turned and raced back at high speed to hide cowering and shaking behind its master’s legs. From then on, whenever that little dog came over it was silent and preferred to stay in the car.
The fight in the dog is important, but knowing your limits is key too… :)
