I don’t know about you, but I regularly wonder what my dog is thinking. When you invest so much time, energy and money into a pet, you suddenly begin to view them as a little person in your life. Suddenly you find yourself saying things like, “I can’t go out tonight because I promised Darcy we’d have a pamper evening,” or “Does the pub allow dogs?”, and just like that, your life changes.

It’s like having a baby, just without the late nights, dirty nappies and tantrums. Instead, you are responsible for a furry creature that rarely does as it’s told and is partial to chewing your slippers. However, unlike a baby, dogs are blessed (or cursed) with the ability to do certain things that humans simply cannot.

They may fool you with their drooling muzzle and hours spent snoozing, but dogs are actually incredibly intelligent…

1. They can detect diseases

Your canine companion has the ability to sniff out scents that the human nose is oblivious to. This phenomenal skill means that they can sniff out a juicy steak in your shopping bag, the aroma of another dog (traitor!) on your clothes and even cancer.

Yes, you read that right, dogs have been known to detect cancer in humans. In 2011, scientists studied a Labrador retriever who was successful in sniffing out colorectal cancer in 98% of stool samples and 95% of breath samples.

As a result of this unique ability, ‘Medical Detection Dogs’ now exist. Their job requires them to alert their handler if they detect cancer or dangerous blood sugar levels in a human. They operate in a similar way to guide dogs for the blind, deaf and disabled, as well as the dogs who work for the authorities, such as the army dogs who seek out bombs and the police pooches who find drugs, traces of blood and corpses. Smart, huh?
