A dog’s sense of smell is way stronger than ours.

Numbers abound about how much better a dog’s sense of smell is than ours. There are so many variables that it’s almost impossible to quantify. I’ve seen figures indicating that a dog’s sense of smell is from 10 to 100 to 1,000 to 1,000,000 times better. Scientists I’ve spoken with say that dogs can detect some, if not most, odors at concentrations of parts per trillion.
