Top Interesting Facts About Dogs


They say that dogs are a man’s best friend – from their unconditional love and loyalty to improving our mental health and giving the best cuddles, it’s easy to see why dogs are one of the most popular animals when it comes to deciding which pet would make a great addition to your family. According to the PDSA PAW Report, the UK is all about puppy love, with 33% of adults owning a pet dog – that’s approximately 13 million in the UK alone!

Whether you already have a canine friend, are looking to get one, or simply want to brush up on your doggy knowledge, we’ve compiled a list of our top interesting facts about dogs…

Dogs and humans go way back

According to research, the first domesticated dogs came about 33,000 years ago, migrating to Europe from Southeast Asia. A DNA study found that dogs actually became self-domesticated, evolving from wolves who had scavenged alongside humans for generations, into the loyal companion that we know and love today. No wonder they’re coined a “man’s best friend”.

They curl up in a ball when they sleep - for a reason!

Have you ever looked at your dog curled up in front of the fireplace, in awe of their cuteness? While dogs love to be cosy, with some even loving a good cuddle with their human, there’s actually a reason why they curl up when they sleep. Deriving from their wolf heritage, this position is all about survival, not comfort. Dogs curl up to keep themselves warm and to protect their vital organs.

Dogs can understand us

The average dog is thought to be as smart as the average 2-year-old, understanding roughly the same number of words and gestures. According to findings from a psychologist and leading canine researcher, dogs can understand more than 150 words, they can count, and they are smart enough to intentionally deceive other dogs and people in order to get treats.

Dogs can sniff-out diseases

The bond between humans and dogs is such that as well as providing loyal companionship –having somewhat of a sixth sense for when their human is emotional, happy or angry, and the ability to aid with accessibility assistance – some dogs even lend their talents to police or medical work. The saying “the nose of a bloodhound” is around for good reason. Dogs have a heightened perception of smell so much that they can help with medical diagnoses.

They have a unique “fingerprint”

Although we’re used to seeing adorable images of animal paw prints, it turns out that a dog’s equivalent to a human fingerprint is actually located in their nose! Just as no two fingerprints are the same, no two dog noses are the same. A dog’s nose pad is so detailed it includes ridges which make up a unique pattern that’s different for every dog and which allows them to be identified.

Dogs show affection...

Dogs are social creatures and thanks to generations of being by their humans' sides, have picked up similar gestures and interactions to display how they’re feeling. Dogs have a number of ways that they like to show affection, from licking to jumping up when they’re excited to see you, to rolling over for a good old tummy rub!

One of our favourites is the classic sigh. If your dog stretches out next to you and lets out a long sigh, they’re happy. Soft vocalisations like sighs and low groans are often signs of contentment in dogs. So if your dog snuggles up and sighs, they aren’t bored, it actually means they feel safe and comfortable by your side.

But they also get jealous

Although animals don’t experience jealousy in the same way we humans do, they may act in a way which suggests they’re jealous by exhibiting assertive, pushy, or rude behaviour.

Seeking our attention, pawing at their human until they are being petted or cuddled, jumping up when socialising with other people and animals, barking and growling, can all be seen as jealous-like behaviours.

A recent study found that dogs exhibited significantly more jealous behaviours (such as snapping, pushing or getting between their owner and an object) when their owners displayed affectionate behaviours towards what appeared to be another animal or human.

Fast, fun facts about dogs

    • According to one study, when a dog does their business, they align themselves with the Earth’s magnetic field! Their sense for the magnetic field also explains why they are great at finding their way around.
