History and origin

The FCI standard says the Thai Ridgeback is an old breed that appears in Thai archaeological documents written about 360 years ago. It was used mainly for hunting in the east of the country, but also to escort carts and as a watchdog.

It kept its original type for so long because the poor roads of eastern Thailand gave it few chances to cross with other breeds. Wikipedia says it is the national dog of Thailand.

How the breed developed

  • About 360 years ago – It appears in Thai documents.
  • 26 May 2003 – The FCI recognises the breed.

Physical characteristics

The standard describes it as a medium-sized dog, with a body slightly longer than it is tall and well-developed muscles. The AKC says its supple body makes it very agile, a natural athlete.

General appearance

The coat is short and smooth. The ridge on the back is formed by hair growing in the opposite direction and must be clearly defined and symmetrical. Wikipedia says there are eight types of ridge: needle, feather, arrow, lute, violin, bowling pin, leaf and saddle; the broader it is, the more it is prized. The AKC says some puppies are born without a ridge.

The standard accepts only solid colours: red, black, blue and very light fawn (isabella). In red dogs, a black mask is preferred.

Training and socialisation

The standard describes it as tough and active, with an excellent jumping ability, a loyal family dog. The AKC gives it 5 out of 5 for watchdog ability and 1 out of 5 for openness to strangers.

It needs an experienced owner, early socialisation and consistent, reward-based training. The fence must be high, as it is an excellent jumper.

Tips for effective training

  • Socialise it early. It is aloof with strangers.
  • The fence must be high. It jumps superbly.
  • Be consistent. It is independent.
  • Keep its mind busy. The AKC gives 4 out of 5 for its need for mental stimulation.

Activity needs and lifestyle

The AKC recommends play in a fenced yard or walks several times a day, as well as search games and tricks. Swimming, hiking and fetch give it a good workout.

Activity How often Why it matters
Walks several times a day Energy
Search games daily A busy mind
Hiking weekly Stamina

Tips for a balanced life

  • The fence must be high.
  • Suited to experienced owners.
  • Check the skin on the back of puppies.

Care and health

Coat and skin care

The AKC says the short, harsh, straight coat needs only an occasional brush; it sheds just once or twice a year. As it has no undercoat, it may bother people allergic to dogs less.

Common health problems

The AKC says most dogs are healthy. Hip dysplasia is rare, and more common is:

Condition Description Common symptoms
Dermoid sinus An abnormal channel in the skin along the back Swelling or infection on the back
Hip dysplasia The hip joint forms incorrectly and, over time, arthritis develops Limping, difficulty getting up or jumping, hip pain

Other care

  • Ask for the puppy to be checked for dermoid sinus.
  • Go for yearly check-ups.
  • Trim the nails regularly.

Diet and nutrition

The AKC recommends good-quality food suited to the dog's age, and attention to its weight.

Tips for a healthy diet

The table gives a starting estimate, calculated with the formula from the Merck Veterinary Manual. The first two calorie columns show the calories per day for a healthy adult dog. The last column shows what this means in dry food with 3,500–4,000 kcal per kilogram.

Dog's weight Calories per day (neutered) Calories per day (not neutered) Dry food per day (approximate)
16 kg 900 kcal 1,010 kcal 220–290 g
25 kg 1,250 kcal 1,410 kcal 310–400 g
34 kg 1,580 kcal 1,770 kcal 400–510 g
  • Treats count towards the daily portion.
  • Split the food into two meals a day.
  • A dog is at the right weight when you can feel its ribs without pressing hard.

Foods to avoid

Some human foods are dangerous for dogs: chocolate, coffee, grapes and raisins, onions, garlic, xylitol (a sweetener used in chewing gum), macadamia nuts and alcohol.

Reproduction and development

Physical and emotional maturity

In dogs, sexual maturity usually comes between 6 and 12 months. Most breeds become adults at around 13–15 months.

Mating and pregnancy

Pregnancy lasts about 63 days, counted from ovulation. Mating a female on her first heat is not recommended. The FCI standard requires that only healthy dogs of typical breed appearance are used for breeding.

Caring for the puppies

In dogs, a litter has 5–6 puppies on average, and the number rises with the size of the breed. Socialisation starts in the first weeks: gentle handling, everyday noises and new people.
