A dog sensory exhibit sponsored by Eukanuba gave people the chance to see, hear, smell and taste as a dog does. "I've always wondered what my dog smells," said one man, sniffing at glass beakers filled with varying intensities of spearmint scent to compare a canine's sense of smell to a human's. Dogs have 125 to 220 million olfactory receptors, says Eukanuba, while humans have a mere 5 million. Bloodhounds have an estimated 300 million olfactory receptors. It means a dog's sense of smell is 1,000 to 10,000 times stronger than a human's.
