Your Canine's Sense of Smell
A much larger part of a dog’s brain is devoted to processing smells than yours. Some search dogs locate people buried under the snow of avalanches, search for evidence in crime, and find people in the water. Cloudy days, mornings, and evenings are the best times for dogs to search. And depending on the conditions, dogs can pick up a scent up to a half a mile away!

Dog Barking Collars - Ultrasonic, Sonic Collars and
Other Devices
Ultrasonic sound can be used to stop barking dogs at a
distance of 25-60 feet. We can’t hear the tones, but dogs
can, the collar supposedly emitting an unpleasant,
high-pitched sound whenever the dog barks. In collar form,
the blast of sound is theoretically triggered by the dog
wearing the collar, but there have been cases of collars
being set off by other dogs’ barking, or even by airplanes
flying overhead.
