Dogs hear approximately four times better than humans in terms of sensitivity and can detect frequencies up to 65,000 Hz, compared to the human upper limit of approximately 20,000 Hz. They can also hear sounds from roughly four times the distance at which humans detect the same sound. This superior
Dogs can detect odors at concentrations roughly 100,000 times lower than humans can, the equivalent of smelling one teaspoon of sugar dissolved in a million gallons of water. Documented detection distances range from several hundred yards in ideal outdoor conditions to miles for trained tracking do

Their visual acuity is approximately 20/75, meaning what a human can read at 75 feet, a dog must be 20 feet away to resolve cle
