Some dogs just have a knack for picking up on things—whether it’s following commands or noticing when something’s amiss.
These breeds are not only intelligent but have the instincts and abilities to uncover things you might wish they didn’t. Here are the 9 smartest dogs who can easily sniff out your secrets:
Border Collie

They are considered among the most intelligent dogs. Originally bred for herding sheep, they are highly perceptive and quick to carry out any commands.
They also have a great sense of direction and can identify exactly which place they need to be in order to carry out the task. Beware, they can sniff out your secret stash of jewels too!
Poodle

People often underestimate poodles, thinking them to be just fancy lap dogs. But they couldn’t be more wrong.
In older days, they were used for retrieving wild game from water. Because of this, their sense of smell and ability to navigate rougher terrain is unprecedented. Just look at those clever, beady eyes–they definitely know what you’d been up to last night!
German Shepherd

They are surely not a surprise entry on this list, since they are frequently used as police dogs.
They are very capable of understanding commands and have a certain ferociousness and determination when it comes to protecting their ‘charge’ or simply figuring out what to do in various situations. Ever seen one sitting quietly with their eyes looking deep into your soul? Yes, they know. And they understand.
Golden Retriever

Like poodles, golden retrievers were also bred as ‘gun dogs.’
The best thing about them is that they can think independently when carrying out their tasks. That makes them so much more useful—and intimidating! They can ‘choose’ to find out whatever they want to!
Doberman Pinscher

Doberman Pinschers were originally bred as guard dogs, but fans of the breed will know them as intelligent, loyal, energetic companions. They are highly trainable, and their instinct to protect means that they have impeccable focus and attention.
Modern Dobermans are much less aggressive than their working ancestors and can make wonderful house pets with consistent training.
Shetland Sheepdog

Also known as the Sheltie, these sheepdogs get their name from being bred on the Shetland Islands.
They were used by farmers to keep birds out of the field and alert the family when a stranger was trespassing on the farm. Beware getting up to mischief with any family that has a Sheltie—you wouldn’t want to piss them off!
Labrador Retriever

This is the quintessential family dog, but they also have a thrilling side to them. They have an extraordinary sense of smell.
They can sniff out the deepest of things—from illicit items to illnesses in humans. So if you’re a smuggler or an illegal hoarder, you gotta be afraid, very afraid.
Papillon

Don’t be fooled by the ‘butterfly’ ears on this one! Having a bit of a weird and goofy appearance, they are probably the smartest dogs on this list.
They excel in sports, agility, and obedience, and have a great sense of intuition that they use to tell when something is wrong. Don’t mess with anyone who owns a papillon!
Australian Cattle Dog

The brave and noble Australian Cattle Dog has many qualities, such as being tenacious, quick-thinking, and really, really driven at their tasks.
They are also quite fiercely protective of their owners—which is why you wouldn’t want them to catch you at some foul play targeting their hoomans!
