Humans have approximately 5 to 6 million scent receptors. Most dogs have between 125 and 300 million scent receptors. There have been studies that state that our scent hounds have between 650 million and 1 BILLION scent receptors!!!
These dogs absolutely need to sniff. It's not something that we should try to let our dogs do, but we absolutely must let them!
