1.   What is a dog?

Dogs are domesticated animals that come in many shapes, sizes and colours. Dogs can have short-hair, long-hair, floppy ears, perky ears, short little legs or some can be almost as tall as a pony! There are a huge variety of dogs but they do have many things in common, such as that they are all descended from the wolf. The modern household dog is a much loved and friendly companion!

2.   How many types of dogs are there?

As people continue to “design” dogs through mixing breeds, this list will continue to grow.

Below are some health and wellness amazing facts about dogs.

1.   What do dogs eat?

Dogs are carnivores – this means they prefer to eat meat. Most domesticated dogs will eat dog biscuits or kibble plus a canned wet food made of meat. However, dogs can also benefit from plant-based foods added into their diet, such as vegetables and grains. Of course, dogs also love fresh meat and treats such as raw bones, pigs ears or dog chews. Their wild ancestors would have relied on their hunting prowess to find rodents and other smaller mammals to eat.

2.   How long do dogs live for?

The lifespan of a dog varies greatly from breed to breed but the average usually falls somewhere between 10-15 years. For example, a Shih Tzu can live up to 18 years whereas a Golden Retriever is expected to live closer to 12 years. In general, smaller dogs tend to have a longer lifespan than large dog breeds.

3.   Do dogs have a superpower?

Dogs do have a superpower of sorts – their nose! They have an amazing sense of smell that can pick up on emotions such as fear and even illnesses like cancer. Dogs are utilised in rescues, airport security checks and house-raids by police to sniff out danger.  A dog can identify smells anywhere between 1000-10,000 times better than humans can! Their ears are also amazing assets and they can hear much more than our human ears.

4.   Do dogs sweat?

Dogs do not sweat like humans do, so how do they expel excess heat from their bodies? You might have noticed your dog panting with their tongue out on particularly hot days. This panting is how dogs sweat! The excess heat is expelled as moisture from their tongues.

5.   How smart are dogs?

Dogs are very clever – we all know they can learn commands such as sit and stay, or even to jump through hoops or do other amazing tricks. It has been found that a dog’s mental ability is on a similar level to a 2 year old human – so your dog may be just as clever and aware as your toddler brother or sister! On average a dog can learn and understand 165 words. Intelligence does vary between the breeds and depends on how well trained your furry friend is.


We have also compiled the best list of interesting facts about dogs that might surprise you!

1.   How long have dogs lived with humans?

Although we originally thought that dogs were domesticated around 11,000 years ago, there is new fossil evidence that suggests that dogs have been living with humans for around 30,000 years – wow! This friendship has grown and developed over the years, from using dogs for hunting purposes to becoming the cuddly pals we see them as today. Studies have suggested that this friendship first occurred by accident through sharing excess meat, thousands of years ago.

2.   Have dogs been to space?

Yes – a number of dogs have been to space! The Soviet Union sent dogs to space in the 1950s to trial their astronaut equipment. However, dogs much prefer being on earth!

3.   Are there any new dog breeds?

In 2020 we welcomed two new dog breeds – the Barbet and the Dogo Argentino. Mixing breeds is an effective way to combine personality and physical traits of dogs – for example, the labradoodle was bred as a guide-dog for people with allergies! The beloved dog is sure to continue to diversify and grow in breed types.

4.   Are any dogs faster than a cheetah?

Technically, no – but a Greyhound could outrun a cheetah. How could that be so? The nimble Greyhound isn’t as fast as a cheetah but has the stamina that the cheetah lacks,  and for that reason would most certainly beat a cheetah in a race.

5.   Are there any Australian dog breeds?

Australian Cattle Dog (also known as a Blue Heeler)

Yes! The Australian Cattle Dog (also known as a Blue Heeler), Australian Terrier, Silky Terrier, Australian Kelpie, Tenterfield Terrier, Dingo, Koolie and Bull Arab are all Australian dog breeds. Australian TV show Bluey (ABC Kids) is of course based around the Heeler family of Blue Heelers. Surprisingly, the Australian Shepherd is actually an American dog breed that originated in California!
