Features Of Dogs

A dog’s nose, ears and teeth tell the story of a born explorer, and this information about a dog’s body shows how each part helps it sniff, hear and run. 

• Size – Chihuahuas can weigh under 3 kilograms, while giant breeds like the Great Dane can weigh over 60 kilograms. 
• Nose – A wet nose helps a dog catch and track scents in the air. 
• Ears – Dogs can swivel and tilt their ears to catch faint sounds, including very high-pitched ones. 
• Teeth – Adult dogs have 42 teeth for tearing, biting and chewing. 
• Paws – Tough, cushioned pads protect a dog’s feet on rough ground. 
• Coat – A dog’s fur can be short, long, curly or wiry, depending on the breed. 

Characteristics Of Dogs

Dogs are pack animals at heart, and these cool facts about their habits explain why they love company, walks and games. 

• Pack Lovers – Dogs enjoy being with their family and can feel lonely when left alone for too long. 
• Eager Learners – Most dogs learn commands and tricks quickly, especially when they are rewarded with praise or treats. 
• Energetic Players – Daily walks and games keep a dog healthy and happy. 
• Body Language Talkers – Dogs communicate through barks, whines, growls and body postures such as the play bow. 
• Loyal Protectors – Many dogs bark to warn their family about strangers or strange noises. 
• Sleepy Habits – Adult dogs sleep about 12 to 14 hours a day. 

Fun And Interesting Facts About Dogs

Some dogs chase their own tails, and others dream of running, so brace yourself for funny dog facts and a few jaw-droppers. 

• Super Sniffers – Dogs have up to about 300 million scent receptors, while humans have only around 6 million. The part of a dog’s brain that handles smells is also far bigger than ours, so a dog can follow a scent trail that is many hours old.
• Sweaty Paws – Dogs sweat mainly through the pads of their paws and cool down by panting. This is why their paws can feel damp on a warm day, and why hot pavements can be uncomfortable for them to walk on.
• Dreaming Dogs – Sleeping dogs often twitch their paws and make tiny noises, a sign that they may be dreaming. Dogs go through the same sleep stages as people, including a deep stage called REM sleep, when most dreaming is thought to happen.
• Newborn Puppies – Puppies are born with their eyes and ears closed, and these open after about two weeks. Until then, they find their mother’s milk by smell and warmth, and they spend most of their day sleeping and feeding.
• Speedy Greyhounds – Greyhounds can run at around 70 kilometres per hour, making them one of the fastest dogs. They are built like sprinters, with deep chests, long legs and flexible spines, yet at home they are famously calm and love a long nap.
• Tail Chasers – Some dogs spin in circles to catch their own tails, often out of play, excitement or boredom. It is usually harmless, but a dog that does it constantly may need a check-up from a vet.
• Howling Choir – Many dogs join in when they hear sirens or music, as if singing along. Howling goes back to their wolf ancestors, who used it to keep in touch across long distances, and some high, long sounds can trigger the same response.
• Super Hearing – Dogs can hear sounds from much farther away than people can, and they can pick up pitches about twice as high. They can also move their ears separately, which helps them work out exactly where a sound is coming from.
• Dalmatian Spots – Dalmatian puppies are born white, and their spots appear as they grow, usually within the first few weeks. In the past, these dogs ran alongside horse-drawn carriages, which is why some are still called coach dogs.
• Heroic Helpers – Dogs work as guide dogs, search-and-rescue dogs and therapy dogs. Others sniff out hidden items at airports, and all of them rely on the dog’s sharp senses and eagerness to learn.
• Strong Swimmers – Newfoundland dogs have webbed feet, a thick water-resistant coat and a powerful build, so they are excellent swimmers. They have a long history of helping fishermen and assisting with water rescues.
• Word Wizard – A border collie named Chaser learned the names of more than 1,000 toys. She could fetch the right one from a pile when her owner said its name, which shows how many words a dog can learn.
• Dog Day – International Dog Day is celebrated on 26 August. It began in 2004 to encourage people to adopt rescue dogs and to honour the work that dogs do.

FAQs

1. Why Do Dogs Wag Their Tails?

Tail wagging shows excitement or strong feelings, but it does not always mean a dog is happy. A loose, relaxed wag is usually friendly, while a stiff, high tail can mean the dog is alert or uneasy. 

2. Why Do Dogs Sniff Each Other?

Dogs read scent messages that tell them about another dog’s age, health and mood. Sniffing is their way of saying hello. 

3. Can Dogs Eat Chocolate?

No, chocolate contains a substance called theobromine, which is harmful to dogs. If a dog eats some, call a vet straight away. 

4. Why Do Dogs Tilt Their Heads?

Dogs may tilt their heads to hear a sound better or to read a person’s face more clearly. It also often earns them extra attention, so they may repeat it. 

5. Why Do Dogs Eat Grass?

Many dogs nibble grass out of habit, boredom, or to settle an upset tummy. Occasional grass is usually harmless, but ask a vet if it happens often or the dog seems unwell. 

Dogs have been listening to us for thousands of years, so it is only fair that we start listening to them. Watch how a dog’s ears, tail and nose tell you how it feels, and you will soon understand far more than barks. Share these facts with your child and ask which one they would most like to tell a friend.
