How many different olfactory receptors do dogs have?
There are four types of receptors involved with olfaction and chemosensation in the dog: OR, vomeronasal receptors, trace amine-associated receptors, and formyl peptide receptor-like proteins. Most research on the genetics canine olfaction has been focused on OR genes.
How many more smell receptors do dogs have than humans?
They have more than 100 million sensory receptor sites in the nasal cavity as compared to 6 million in people, and the area of the canine brain devoted to analyzing odors is about 40 times larger than the comparable part of the human brain.
How many smells can a dog smell?
The Nose Knows Humans have only 5–6 million scent receptors in our noses. Depending on the breed, dogs have up 100 million or more scent receptors in their noses. And those terrific trackers we know as Bloodhounds have 300 million! Dogs can detect some smells in parts per trillion.
How many olfactory receptors do cats have?
A cat’s sense of smell is far more advanced than ours. When compared to humans, cats have a smelling ability that is 14 times more sensitive. The human nose contains about 5 million olfactory receptors that detect aromas, while a cat’s nose has 45 to 80 (possibly up to 200) million scent receptors.

How many scent receptors do dogs have?
The passage through which dogs smell the air contains highly specialized olfactory receptor cells, which are responsible for receiving smells. A dog contains about 225-300 million smell receptors, as compared to just 5 million of these receptors being present in a human nose.

When dogs exhale, they send air out through the slits of their nose, but the manner in which this air is exhaled through their nose helps the dogs to draw in new odor molecules . This also helps dogs capture more smells when sniffing.

The Olfactory bulb accounts for one eighth of the dog’s brain. The Olfactory bulb is extremely important to the dog due to its function of processing scent. Scent information travels from the Olfactory bulb to the limbic system which is the most primitive part of the brain (dealing with emotions, memory and behaviour).
