sense of smell and animals

my son asked me which animal has the strongest sense of smell.

actually, he asked what animal smells best?
and he confused my little brain for a second

off the top of my head, i had to guess a shark, it can detect a drop of blood in 1 cubic mile of water,

but i don’t know if that’s the correct answer. does anyone know of an animal with a more powerful sense o’ smell than sharks?

as far as best smelling animal, geez, i’m clueless, they all seem pretty smelly.

although, my mom’s dog, after rolling in filth and tangling with a skunk has my vote for worst smelling animal
