Your dog is probably a better doctor than you’ll ever be.
Just like us, dogs dream, and they possibly dream about doing doglike things.
Just like humans, a dog's sleep cycle has an REM phase, where most of our dreaming occurs.
Stanley Coren, author and professor of psychology, told Live Science, “What we've basically found is that dogs dream doggy things. So, pointers will point at dream birds, and Dobermans will chase dream burglars.” ADORABLE.
Dogs can literally smell out certain human diseases.
The human nose has about 5 to 6 million olfactory receptors, compared to 220 million for a pooch.
A 2009 study in which dogs tried to detect cancer by smelling breath samples of patients had a success rate of around 90%. That's incredible to think about.

But also, dogs can see in the dark far better than humans.
While dogs have fewer cones in their eyes, they have more light-sensitive cells, or rods, toward the center of the retina. A larger pupil also lets in more light.
Don't go by this GIF, though. It must have been hella dark.
