Dogs have higher rod cell concentration allowing better peripheral and motion detection in dim light than humans.
More Rods
Tapetum tissue behind dog retinas acts like mirrors amplifying available light at almost 45 degree angles for enhanced images.
Reflective Eyes
Humans spot detail best straight ahead while dog peripheral vision excels picking up shifts in dark surroundings.
Periphery Power
Sighthounds like greyhounds have supreme night sight while floppy eared breeds lose some capacity hampered by covered eyes.
Vary By Breed
Dog limited color vision utilizes rod clarity at night rather than cone color detection less functional in darkness.
See Some Color
Though physically equipped for basic nighttime navigation, most dogs rely heavily on nose sense over sight.
Scent First
Quickly turning on lamps or cameras with night vision settings impairs adjustable night vision capacities.
Avoid Bright Lights
