This dog didn't recognize his owner until he sniffed him.

Not in any reality do we deserve dogs.

This is why I like dogs better than 95% of the people I meet.

this is why whenever you see a dog go up to another dog they always sniff there asses before they shake hands

I'm not crying, you're crying :'(

damnit you beat me to crying

It's pretty incredible how dogs use their sense of smell.

Supposedly dogs are able to detect the passing of time by the diminishing scent in a room. That is how they know about the time their owner gets home from work.

Bears have an even better sense of smell than dogs. A bear’s sense of smell is 7 times better than a blood hound’s or 2,100 times better than a human.

And sharks supposedly have an amazing sense of smell but screw those murderous fish. I lost a brother in the last sharknado.

Polar bears can smell a seal from 20 miles away if the wind is right.

Nothing much. What's up with you?

Good human
