Dog

The dog is a domesticated subspecies of the grey wolf. It lives alongside people across nearly every climate and culture, and it is the most common companion animal kept in homes. Dogs form strong bonds with the people who care for them, and many breeds were developed to work closely with humans at tasks such as herding, hunting, guarding, and retrieving.

As a species, the dog covers an enormous range of sizes and temperaments. A small companion dog may weigh under 5 kg, while a large working dog can exceed 50 kg. This variation is the result of selective breeding over thousands of years, which shaped body type, coat, energy level, and instinct to suit different roles.

Dogs are social animals that need daily contact, exercise, and mental activity. They communicate through body posture, facial expression, and vocal sounds, and they read human cues closely. A dog that receives enough attention, structure, and physical activity settles well into a household routine.

Who the dog suits

In Singapore, the type of housing you live in determines which dogs you may keep. HDB residents are permitted only breeds from the approved small-dog list maintained by the Housing Development Board, while those in private housing or condominiums have a wider selection. A dog suits a person or family able to commit to daily walks, company, training, and veterinary care for the animal's full life. Breed energy levels vary considerably, so choosing a type that fits your living space, working schedule, and outdoor access matters before making a final decision.

Dog breeds vary more than those of almost any other domesticated species. Differences appear in body size, leg length, head shape, coat type, colour, energy level, and instinct. Much of this variation traces back to the jobs breeds were developed to do. This catalogue records 298 breeds, sorted into working groups based on their original purposes.

Many of the example breeds below are sporting dogs, bred to find, flush, point, or retrieve game alongside a hunter. Within that broad role, retrievers fetch downed game from land or water, spaniels flush birds from cover, setters and pointers locate and indicate game, and water dogs work in wet conditions.

How breeds are grouped

Kennel and breed organisations sort dogs into groups by function and shared history, such as sporting, working, herding, hound, terrier, toy, and non-sporting types. A breed is recognised when it has a stable population, a written standard, and predictable traits passed from parents to offspring. Prospective owners in Singapore should confirm their chosen breed appears on the HDB approved list before acquiring one. Many popular dogs today still carry the instincts of the work their group was bred for.

The dog descends from the grey wolf and was the first animal that humans domesticated. Genetic and archaeological evidence places this process at least 15,000 years ago, and some estimates push it further back. Early dogs and people lived together before the rise of farming, which makes the dog older as a domestic animal than livestock such as cattle or sheep.

Domestication likely began as wolves that tolerated people fed near human camps and gradually grew tamer across generations. Over time, the animals that were calmer and more useful to people were the ones that stayed and bred. This produced a population distinct from wild wolves in behaviour and, later, in body and coat.

As human societies spread and took up herding and farming, dogs took on defined jobs. They guarded camps and flocks, helped hunters, moved livestock, and pulled loads in cold regions. Different regions favoured different traits, so local types began to diverge in size, coat, and temperament according to climate and task.

Most of the highly distinct modern breeds were fixed much more recently, largely over the past few centuries, when written standards and formal breeding records became common. This formal breeding sharpened the differences between types and produced the large number of recognised breeds kept today, including the many sporting dogs developed to work with firearms.

Across the species, dogs share a common body plan: four legs, a tail, a muzzle with strong jaws, and ears that may stand erect or hang down. They have a keen sense of smell and good hearing. Beyond that frame, physical traits differ enormously between breeds, which is why a tiny companion dog and a large working dog can look so different while belonging to the same species.

Size is the most obvious variable. Adult dogs span from very small toy types to large breeds taller than 70 cm at the shoulder. Coats range from short and smooth to long, wiry, or tightly curled, and colour patterns cover solids, mixes, and markings.

How appearance varies between breeds

Appearance tracks the job a breed was bred for. Retrievers such as the Golden Retriever and Curly-Coated Retriever carry water-resistant coats, while pointing dogs like the German Shorthaired Pointer are built lean for stamina. Coat length and density often match the climate the breed worked in. In Singapore's year-round heat and humidity, short-coated or lightly coated breeds manage daily conditions more easily than dense double-coated types, which need extra care to stay cool and comfortable.

Dogs are social animals descended from a pack-living ancestor. They form strong attachments to the people and animals they live with, and most prefer company to being alone. Prolonged isolation can lead to stress and behavioural problems, which is a real consideration in Singapore households where working hours tend to be long. They look to their household for structure and respond well to consistent routines.

Communication happens through body posture, tail and ear position, facial expression, scent marking, and a range of vocal sounds including barking, whining, and growling. Many breeds carry instincts from their original work. Sporting breeds such as the English Springer Spaniel and German Wirehaired Pointer often have a strong drive to follow scent, flush, and retrieve. A breed's typical noise level and ability to settle in a smaller space are worth factoring in when choosing a dog for flat living.

Daily care

• Provide one or more walks or active play sessions each day, scaled to the breed's energy
• Feed measured meals on a consistent schedule and keep fresh water available at all times
• Give attention and company; dogs do poorly when left alone for long stretches
• Offer mental activity such as training, sniffing time, or toys to prevent boredom
• Clean up after the dog in all public areas and keep its resting area tidy

Environment

• Give the dog a defined indoor space with a clean, comfortable bed
• Keep hazards such as toxic foods, cleaning products, and small swallowable items out of reach
• Ensure good ventilation and shade outdoors; Singapore's year-round heat and humidity make heat stress a genuine risk, so avoid exercising dogs during the hottest midday hours
• Use a secure enclosure or a leash to prevent escape and roaming

Grooming and handling

Grooming needs depend on coat type. Short-coated dogs need occasional brushing, while long, wiry, or curled coats need frequent brushing and sometimes professional trimming. In Singapore's humid climate, regular grooming and thoroughly drying the coat after walks help prevent skin problems. Routine care includes nail trimming, ear checks, and dental care. Handle dogs calmly and predictably so they stay comfortable with brushing, veterinary visits, and bathing.

Dogs are omnivores with a diet built around animal protein but able to use fats, carbohydrates, vitamins, and minerals as well. A complete and balanced commercial dog food formulated for the dog's life stage meets the nutritional needs of most dogs. Portion size depends on the dog's size, age, and activity level, and overfeeding is a common cause of weight problems.

Treats should stay a small share of daily calories so the main diet remains balanced. Most dogs on a complete food do not need extra supplements unless a veterinarian advises one for a specific condition. Fresh, clean water must be available at all times and refilled regularly.

Most dogs are healthy with routine care, a balanced diet, and regular exercise. Average lifespan is around 10 to 13 years, though smaller dogs often live longer than large breeds. Health needs change with age, so puppies, adults, and seniors each call for slightly different attention. In Singapore, veterinary clinics are widely available and several offer annual health packages covering vaccinations, dental checks, and weight screening.

Preventive care

• Keep up with vaccinations and parasite control, including tick and flea prevention, as advised by a veterinarian
• Schedule regular check-ups, including dental and weight assessment
• Keep the dog at a healthy weight with measured food and daily activity
• Brush teeth and check ears, skin, and nails on a regular basis

Dogs are among the most trainable of domestic animals. They read human cues closely and learn quickly when training is consistent and rewarding. Trainability varies by breed and individual, but nearly all dogs benefit from basic obedience and from early exposure to people, places, and other animals. Many sporting breeds, such as the Brittany and the Golden Retriever, were bred to work with handlers and tend to take readily to training. In Singapore, obedience classes and puppy socialisation programmes are available through various training schools and community clubs.

Getting started

1. Socialise the dog early to a range of people, sounds, and situations
2. Teach a few core cues first, such as name response, sit, and recall
3. Keep sessions short and frequent rather than long and rare
4. Reward the behaviour you want with food, praise, or play right as it happens
5. Stay consistent across everyone in the household so the rules are clear

Dogs typically reach sexual maturity within their first year, though responsible breeding usually waits until the dog is older and fully developed. Females come into season periodically rather than continuously. After mating, gestation lasts about 63 days on average. Litter size varies with breed: small breeds often have a few puppies, while large breeds can have a dozen or more.

Puppies are born blind and deaf and depend fully on the mother in the first weeks. They begin to see and hear within about two weeks, then start to walk, play, and wean over the following weeks. The period of early socialisation with littermates and people is important for stable adult behaviour. In Singapore, dog breeders are required to hold a licence from the Animal and Veterinary Service, and regulations cover breeding conditions and animal welfare. Breeding should be approached responsibly, with health screening for both parents before any mating.

Is a dog right for you?

A dog is a long-term commitment that often lasts more than a decade. In Singapore, the first question to ask is whether your housing type permits the breed you want. HDB residents may only keep dogs from the approved list, and those in condominiums should check their management corporation's rules as well. Beyond housing, weigh the daily time for exercise, feeding, training, and company, the space available indoors and out, and the ongoing cost of food, veterinary care, grooming, and supplies. Match the breed to your actual routine and living situation.

Where to get one

In Singapore, dogs can come from licensed breeders, pet shops, or welfare organisations such as SPCA Singapore and local shelters. The Animal and Veterinary Service (AVS) requires all dogs to be licensed, microchipped, and vaccinated. Adopting from a shelter is worth considering, as dogs of many ages and temperaments are available, including adults whose character is already known. Avoid any source that cannot show vaccination records or explain how the animals were raised.

Registering your dog and its microchip in Singapore

The Animal & Veterinary Service requires every dog here to be licensed and microchipped by three months of age, so the chip is settled law; what stays on you is the record behind it. A free United Pet Club profile holds your contact details against your dog for as long as the dog is yours, and it works even if he somehow ends up outside Singapore. Registering your dog takes minutes and never costs a cent.

The AVS listing and a searchable contact record are two different things, and the second one is yours to set up. Register the microchip on the free lifetime plan: any chip brand a local vet implants qualifies, updates after a move between flats stay free, and the record can be pulled up 24 hours a day from anywhere. Create your free account and settle both before the evening walk.
