The dog sense of smell is the most powerful sense of this species, the olfactory system of canines being much more complex and developed than that of humans. [ 1] It is believed to be up to 10 million times as sensitive as a human's in specialized breeds. Dogs have roughly forty times more smell-sensitive receptors than humans, ranging from ...

Our human olfactory sense is one of the most phylogenetically primitive [ 1] and emotionally intimate [ 2] of the five senses; the sensation of smell is ...
Dogs are dichromat and less sensitive to differences in grey shades than humans and also can detect brightness at about half the accuracy of humans. [2] The frequency range of dog hearing is approximately 40 Hz to 60,000 Hz, which means that dogs can detect sounds far beyond the upper limit of the human auditory spectrum. [3] n/a.
According to pet behaviorists, "whale eye" is something that they would love for dog owners to take notice of. As dog behaviorist Kerry Stack, founder of Darwin Dogs Training, says, dog bites ...
Dogs have around 1,700 taste buds compared to humans, with around 9,000. The sweet taste buds in dogs respond to furaneol.
