Dogs

What is a dog?

Though their exact origin is unknown, domestic dogs developed from wolves—either grey wolves or another, now extinct kind of wolf. Based on genetics, dogs descended from wild forebears between 14,000 and 29,000 years ago via human contacts.

Though every variant of the more than 400 dog breeds is a member of the same species, Canis lupus familiaris, all are descended from other wild canines, such as foxes.

Dogs come in different kinds and sizes, from little miniature Chihuahuas to massive Great Danes. For toy poodles, dog weights fluctuate greatly, from 1.8 kg (4 pounds) to 104 kg (230 pounds) for the biggest mastiffs.

Originally probably created for hunting, humans employed basic forms of genetic engineering to produce dogs with particular instincts and traits.

Though there are still numerous contemporary professions for dogs, from offering services to individuals to detecting wildlife crime, many people retain pet dogs for comfort and company nowadays.

Sadly, feral canines may wreak havoc in their local ecosystems mostly by eating native animals, which causes significant population losses.

What is a dog’s scientific name?

Dogs are scientifically named Canis lupus familiaris.

A domesticated variant of grey wolves (Canis lupus), they are Though they all belong in the same species, there are more than 400 different dog breeds.

Where do dogs live?

Dogs abound in the world these days. Originally prevalent all over the northern hemisphere, grey wolves were the most common mammal on the globe at one time.

Evolution

Natural selection combined with human impact helped dog evolve from gray wolves over thousands of years.

Studies reveal that between 14,000 and 29,000 years ago, the first wolves were domesticated. Scientists still disagree on the precise chronology and specifics of this domestication process since there were probably multiple rare cases of wolves being tamed at various locations at different periods.

Grey wolves and humans first began forming a mutually beneficial partnership about 20,000 to 40,000 years ago. Various packs of wolves at various locations entered this link in different ways. Wolves in northern Eurasia, for instance, most certainly helped in their own domestication by following around nomadic people and consuming the remnants of animals and other food waste these people left behind.

A kind of natural selection took place over time. In this new habitat, wolves less hostile to humans and more accepting would have been more likely to flourish.

Since wolves are wild creatures, it’s not apparent exactly how they grew at ease cohabiting with humans. Once they did, though, people started breeding them using basic sorts of genetic engineering to create particular instincts and traits.

First dogs

The first dogs were probably raised for protection, hunting, herding animals, labor, and hauling sledges in the cold. Huskies were developed to tolerate frigid temperatures, German shepherds to herd animals, and dachshunds for their capacity to pursue badgers into tunnels.

Dogs’ functions changed as human communities grew and varied; new breeds arose depending on particular requirements and tastes. Human selective breeding highlighted several physical and behavioural features, which produced the great range of dog breeds we know today.

Dogs as pets

Over time, people started breeding dogs for companionship instead of for labour. Dogs are common pets today, and there are hundreds of various breeds.

Let’s review the main groupings of dog breeds along with their traits.

• Often with thick, water-repellent coats, these dogs help hunters capture and retrieve feathered prey. Among the sporting breeds are cocker spaniels and Labrador retrievers.
• Bred dogs are sleek, have long legs, and can run very quickly for brief bursts. They are driven to chase warm-blooded, rapid prey. Greyhounds and bloodhounds are two hound breeds.
• These dogs evolved to help people with everyday chores such as sledging and protecting flocks or homes. Among the working breeds are rottweilers and Great Danes.
• Terriers were developed to hunt rodents and vermin under ground. They have small legs and a fuster. Among the terrier breeds are bull terriers and Scottish terriers.
• Toy group: Often small enough to fit on your lap, toy dogs were developed for human company. Popular toy breeds consist of Chihuahuas and pugs.
• Herding canines with great natural intelligence and energy were created for moving cattle and sheep. Among the herding dogs are German shepherds and border collies.
• Non-sporting group: This group comprises everything left over—dog breeds not fit for the others. Among the non-sporting breeds are poodles and Dalmatians.
• Among the several advantages of owning a dog are less loneliness and stress, more mobility and exercise encouragement, and the support of socializing with other dog owners. It has also been demonstrated that owning a dog at home elevates your mood. Study after study has shown that dogs raise human oxytocin levels.

Dogs with jobs

Many canines these days work for everything from therapeutic purposes to law enforcement assistance.

Among the several notable and crucial dog jobs are:

• Therapy dogs are emotional supporters.
• Dogs were employed to find animals that needed to be rescued from the terrible 2020 Australian bushfires, therefore helping humans and animals with search and rescue.
• Using their keen sense of smell, medical dogs can identify disorders including Parkinson’s, diabetes, epilepsy, cancer, and others
• Dogs from the military and police have been used to detect explosives, track down people or evidence, and identify animals or animal parts trafficking. They have also been used to combat wildlife crime.
• Guide or support dogs for people with additional needs, including blindness.

Disaster preparedness

Every day, our pets depend on us for food, cover, water, and lots of belly rubs; yet, in an emergency, they become much more dependent on us.

You should get your dog ready for a possible tragedy by:

• Microchip them and keep them current with the microchip database for your data.
• Frequent vaccinations for them
• Get them at ease using a container or carrier.

Making a pet catastrophe kit filled with everything you can possibly need in the event of an emergency is also a smart idea. This should entail:

• Enough to last two or more weeks.
• Getting water
• Picture you with your dog here
• a collar including an ID tag
• Medical records
• Dog container or carrier
• Bowls for food and drink
• a harness and/or lead
• Every prescription your dog requires
• If wearing a muzzle or other protective gear is necessary,

The threat dogs pose to wild animals

Sometimes dogs threaten wild animals via predation, outcompeting them for food, interbreeding, and disease transmission.

Wild or feral dogs endanger around 200 IUCN Red List-assessed species, according to the Global Invasive Species Database.

Dogs in the Serengeti-Mara ecosystem in East Africa, for instance, can transmit the canine distemper virus (CDV) to wild species, therefore influencing silver-backed jackals, bat-eared foxes, and threatened African wild dogs.

A closely related virus that dogs also carry also affects lions, hyenas, bat-eared foxes, and leopards in the Maasai Mara National Reserve.

Feral domesticated dogs and pet dog who let go of their leashes are also endangering wildlife. Just one German shepherd killed an estimated 500 native Kiwi birds, according to New Zealand research.

Humans are usually in charge of lowering these risks and shielding threatened or endangered animals from harm when it comes to domesticated dogs. When your pets go outside, you must keep an eye on them and keep them on leashes in order to protect wild wildlife.
