A dog’s sense of smell is 1000 to 10 million times more sensitive than that of humans? Also the part of the canine brain that is responsible for their olfactory sense is about 40 times bigger in size than that of humans, even though the human brain is bigger in than the dog brain, relative to size. The number of scent glands that a dog possesses primarily depends on the breed; it can range between 125 million to 300 million scent glands.
Puppies are born deaf, but their ability to hear quickly surpasses that of humans, as they grow into maturity. Dogs are able to hear within a frequency range of 67 to 45,000 hertz (cycles per second), which means they can hear ultra-high pitch sounds; this is something that human ears are unable to recognize. Humans are only able to hear a frequency range of 64 to 23,000 hertz. However, the sense of hearing gradually deteriorates in both dogs and humans as an age-related change.
