I Hope Their Night Vision is Better Than Ours
We have farm fields bordering two sides of our house, and those sides are naturally where we walk the dogs. One is an 18 month old GSD and the other is a 9 year old Dobe/Shepherd mix. Both black as night with some tan tossed in in the usual locations.
Living in the country, it is DARK out at night. Some nights you can't see your hand in front of your face. Forget about being able to see the dogs on those nights. Even with a flashlight finding and tracking them with the beam is difficult.
The normal routine is that they will trot out into the field and find their "special spot", do their business, and then run back just as fast as they can, sometimes from 100 yards away.
When I hear the dogs running flat out at me all I can do is turn my back to them and pray that they can see better than I can, because I can't see squat out there.
So far, there has never been a collision, but I don't know if I'm just lucky and should be updating my will.
I just did the math. Lets take an 80lb dog running at 20mph (pretty slow actually, I had one that could do 32) which is 33 feet per second. If said dog collides with a squishy object (me) and takes an entire second to expend his kinetic energy (bones breaking takes time), he will impart 2640 ft/lbs of energy, which happens to be the muzzle energy of the worlds most powerful factory handgun cartridge, the 500 S&W Magnum.
Dogs can see really good at night, right? Right?
