Thai Ridgeback

Also known as: Thai Lang-An, Siamese ridgeback, Thai ridgebag dog

The Thai Ridgeback is one of the oldest and least crossbred Southeast Asian breeds, developed in near isolation in Thai villages where it hunted, guarded property, and pulled carts. An adult weighs around 25 kilograms on an athletic, muscular frame, and its defining trait, the reverse-growing strip of hair along the spine, comes from the same genetic quirk that also produces a distinctive skin fold on the neck. The short, smooth coat is easy to maintain. The breed still carries a marked independence and strong territorial instinct that echoes older, less domesticated types. Early socialization matters a great deal, since an adult raised without it can be difficult around other animals. It tends to be close with its own handler but distrustful of strangers. Life expectancy runs 12 to 13 years.

Living with the Thai Ridgeback

In Thai villages these dogs hunted, guarded the house and largely looked after themselves, and that independence has not worn off. A Thai Ridgeback is energetic, fast and endlessly curious, and it needs long walks, running and something for its brain to do. Left at home with nothing to do, it will find its own project, and you are unlikely to approve of it.

It is sharp, but obedience doesn't come as standard: it asks "why?" and waits for a good answer. Train it calmly and consistently with generous rewards, start on day one and don't rush. The prey drive is very strong, so a cat, a pigeon or a hare can end any lesson in a second; let it off the lead only somewhere securely fenced, and make the fence tall, because this dog jumps like a spring.

It is loyal and attached to its own people but shows affection with restraint, and it distrusts strangers and watches them closely. It is an alert guard that doesn't bark for nothing, so when it does bark, there is usually a reason. Around small children and other dogs it needs plenty of early socialisation and your supervision; this is a dog for an experienced owner who values character more than obedience.

Grooming and coat

A Thai Ridgeback's coat is so short and close that it feels like velvet, and it needs a brush no more than once a week: a rubber mitt lifts the loose hair and brings up the shine in a few minutes. It sheds little, but such a thin coat gives almost no protection from the cold, so on a winter morning a warm dog coat is not decoration but a necessity. As your hand goes over the dog, look at the skin too: every scratch, red patch or lump shows under a coat like this, and with a young dog it's worth feeling carefully along the middle of the back.

The ears stand up and are open to view, so they are easy to check: once a week, see that they are clean inside and odour-free. Look at the eyes in daylight, especially after a run through the undergrowth; they should be clear, with no redness or discharge. Trim the nails every few weeks, since even an active dog doesn't always wear them down, and brush the teeth several times a week.

Health and possible conditions

Twelve or thirteen years of running, clearing fences and lying in the sun: that's the life you can expect with a Thai Ridgeback, and its health list has only two entries. One concerns the joints, the other the skin along the middle of the back, and both are worth knowing about before you choose a puppy. The list is not here to frighten you; when something raises a question, a vet decides.

This is general information, not veterinary advice. For your own dog's health, tests and treatment, see a vet.

Hip dysplasia

This is a fault in how the hip joint develops: the head of the thigh bone doesn't sit properly in its socket, so the joint wears over time. You might notice your dog struggling to stand after a rest, bunny-hopping with its hind legs when it runs or starting to refuse the jump into the car. A Thai Ridgeback loves sudden sprints and high leaps, so show any change in gait to a vet, and if you are getting a puppy, ask the breeder about the parents' health testing.
Dermoid sinuses

A dermoid sinus is a narrow channel, present from birth, that links the skin to deeper tissue, and in ridgebacks it turns up along the midline of the back. Running your fingers gently down a puppy's spine from neck to tail, you might feel a tiny opening or a tuft of hair poking out, and sometimes the spot leaks or swells. Let a vet assess anything like that, and when choosing a puppy, ask the breeder about the parents' health testing.
