Thai Ridgeback Dog

Other names: Thai Ridgeback, TRD, Thai Dog, Mah Thai, Lung Arn

Thai Ridgeback Dog

This stunning, tough, alert and energetic dog originates from Thailand over 4,000 years ago but has since gained popularity in the Western world. The Thai Ridgeback is fiercely devoted and protective of its family, and so, must be well-socialised and trained to prevent aggressive behaviour towards strangers.

With that said, this breed is loyal, affectionate and loving towards the people it knows and trusts. It makes a wonderfully playful and energetic pet when handled in the right way. Be warned, though - this is a smart, independent breed which can be a little unpredictable. The Thai Ridgeback also has an extremely strong prey-drive and normally can’t be kept around cats or small animals.

Origins and history

The Thai Ridgeback is the national dog of Thailand and is believed to have originated there over 4,000 years ago. It’s considered a ‘primitive dog’ due to its wolf-like characteristics. The breed is thought to originally have thrived in Eastern Thailand. However, the exact origins of the breed are unknown and still debated to this day.

This breed is certainly impressive, with a strong, tough, yet elegant appearance. This is a medium-sized breed with a muscular, sturdy, squarish body with long, lean legs. Their skin is visibly loose, especially around the back of the neck. Females are always significantly smaller than males.

They have a distinct ‘wedge’-like head and wrinkled forehead skin. The ears are wide-set, alert and slightly forward, the eyes are expressive and almond-shaped and the nose is black. Often, Thai Ridgebacks have spotted tongues.

Good to know

The defining feature of this beautiful dog has to be the wolf-like ridge of hair running along the back. It grows in the opposite direction to the rest of the coat and has been identified in eight different patterns - feather, arrow, needle, lute, violin, bowling pin, saddleback and leaf.

  • 100%


    The Thai Ridgeback survived in the wilds of South East Asia for hundreds of years - so it's not surprising that their prey drive is particularly high. They will chase and may try to kill pretty much any small animal, including cats. A lot of care needs to be taken when other animals are around - invest in a strong harness and lead!

    Fearful / wary of strangers

    This breed is extremely wary and suspicious of strangers and can be aggressive towards them if not socialized from a young age. A well-socialized Thai Ridgeback may act aloof towards unfamiliar faces but is unlikely to turn aggressive.

      Easy to train / obedience

      Looking for an easy-to-train, obedient, calm dog? The Thai Ridgeback isn’t the one! Despite their intelligence and ability to learn fast, this breed is stubborn and therefore, difficult to train. They will (yes, it’s a definite!) test boundaries and behave badly if allowed to get away with it. 

      We can’t stress enough that intensive training and socialization of the Thai Ridgeback is essential. Without it, they really could be a nightmare pet, through no fault of their own. Therefore, it’s essential that only experienced dog handlers adopt this breed.

        Thai Ridgeback Dog in a flat

        This breed may be able to tolerate a flat, providing they’re given regular, fast-paced walks to burn off their energy. However, in an ideal situation, they’ll live in a house with a secure back garden to safely roam around.

        Need for exercise / Sporty

        The Thai Ridge was bred as a working dog and so, requires lots of exercise. Without it, they may become destructive and irritable. Ideally, they need multiple walks throughout the course of the day as well as plenty of playtime and ball games. The more exercise you can provide, the more pleasant this breed will be to live with.

        Travelling / easy to transport

        Its size allows it to follow its owner everywhere without too much difficulty but the Thair Ridgeback requires a lot of work on socialisation.

          Thai Ridgeback Dog and dogs

          When socialised intensively from a young age, the Thai Ridgeback should be able to co-exist peacefully with other dogs in the family. However, you should introduce them slowly before committing, as not all dogs will get along - especially males. They’re tough cookies and may become aggressive towards other dogs if they feel threatened.

          Thai Ridgeback Dog and the elderly

          The Thai Ridgeback may be a good companion and watchdog for a particularly active elderly person or couple. However, if vigorous daily exercise can’t be guaranteed, they’re best avoided.



          A Thai Ridgeback puppy is rather expensive - you’re looking at £1500 or more.

          Concerning your monthly budget, on average, this dog would cost you between £30 to £40.


          One of the best things about the Thai Ridgeback is their low-maintenance grooming. Their short, hard and straight coasts need no more than a weekly brush and a wipe down when they get a little mucky. They’ll also need an occasional bath. A few times a year maximum is best, as overly-regular bathing can dry out and irritate their skin.

          This breed’s nails grow rapidly and should be checked and trimmed regularly. As with any other dog breed, make sure to check the eyes and ears, check for signs of infection and clean them if necessary. You should also brush their teeth as much as possible - at least once a week, but ideally daily.


          The Thai Ridgeback doesn’t shed much and may be a good choice for those sensitive to dander. A weekly brush will help to minimize the shedding even further.

          Nutrition of the Thai Ridgeback Dog

          As a highly active breed, the Thai Ridgeback should be fed high-quality, complete and balanced dog food which is formulated specifically for active dog breeds. Remember to choose the appropriate food for their age - i.e. puppy, adult or senior.

          Health of the Thai Ridgeback Dog

          Life expectancy

          The Thai Ridgeback lives, on average, for around 11 - 13 years.

          Strong / robust

          This breed is extremely strong, agile and athletic - a real tough cookie. They’re known to hunt cobras in Asia - so if that’s not strong, we don’t what is!
          However, this breed is not adapted to very low temperatures.

          Withstand heat

          Originating from a tropical country, the Thai Ridgeback copes incredibly well in warm weather and loves soaking up the sun. That’s not to say they don’t need access to shade and water, though - they’ll still get hot in burning sunshine.

          Withstand cold

          It’s best to keep a Thai Ridgeback indoors when the weather turns chilly - they won’t enjoy the cold weather and do not have adequate protection for the cold in terms of their coat.

          Tendency to put on weight

          The Thai Ridgeback is an active, agile breed and isn’t prone to gaining weight. However, in a domesticated setting with minimal exercise, they may pile on the pounds - especially if they’ve been spayed or neutered. Make sure you’re taking your dog on regular walks and continue weighing out food portions throughout their life to prevent overfeeding.
