When you're experiencing heartbreak, your pup's heart breaks a little too (they're so empathetic!). And when it's time for his bath, he does his best to dodge the soapy water by finding a safe place to hide! When you stop and consider all the things a dog can sense, it's pretty crazy. You'll feel truly thankful for your pooch's sixth sense after reading this, especially number 3!

1. Dogs Know When You Are Sad

When you feel sad, your dog will immediately pick up on this and adjust his behavior accordingly. He may become more subdued than usual, lose interest in his toys and even refuse his food.

2. Dogs Can Sense Your Intentions

Even before you turn on the shower or touch his towel, your dog knows you intend to give him a bath and will immediately run for cover. The same goes for haircuts, nail trims and administering medicine.

On the other side, your dog will also understand if your intentions are pure and you are performing the task for his own good.

3. Dogs Can Sense Any Diseases You Might Have

If your dog has been paying particular attention to a certain area of your body, you may want to visit your doctor to make sure everything is okay.

Various studies have confirmed that dogs have the ability to detect certain diseases such as cancer through their keen sense of smell.

Some dogs can even be trained to warn epilepsy sufferers when they are about to have a seizure.

4. Dogs Understand When You Feel Scared

If you feel scared, your dog will know about it in an instant. A dog’s sensitive nose can pick up on subtle scents, such as adrenalin, that he associates with fear and danger.

If you have a Rottweiler or Doberman, then your burly protector will most likely spring into action and come to your rescue.

Smaller dogs, or those with nervous temperaments, will follow your lead and start to feel scared themselves.

Your dog will always look to you for guidance on how to react in certain situations, so if you want your dog to be brave you will have to lead by example.

5. Dogs Know When You Are Being Unfair 

Your dog will immediately understand if you are playing favorites.

A study performed in Austria tested what would happen if one dog was rewarded for performing a trick while another was not given anything for completing the same task.

he dogs that did not receive a reward became agitated at the sight of their peers receiving treats. They responded by scratching and licking themselves with impatience. In other words, they recognized the unfairness of the situation.

Many animals have a sense of justice. Chimps, for instance, have a very strong sense of right and wrong and even take pleasure in punishing those who break the rules. Dogs have their own sense of fairness and it results from their social structure.

One reason that dogs understand fairness arises out of their roots as wolves. Researchers have found that, because wolves must coordinate as a pack to hunt, they depend upon rules of fairness to survive.
