When Does a Thai Ridgeback Stop Growing?

Most Thai Ridgebacks reach adult height of 20–24 inches by 12–15 months, with full body weight of 35–75 lbs achieved shortly after. Males fill out to 75 lbs while females reach 66 lbs.

Growth rate is influenced by genetics, diet quality, and spay/neuter timing. Needs vigorous daily exercise and mental stimulation; their athletic ability includes exceptional jumping, so six-foot or higher fencing is essential..

Is My Thai Ridgeback Overweight?

Assessing your Thai Ridgeback's body condition (healthy range: 35–75 lbs):

  • Rib check: Run your hands along the ribcage—you should feel individual ribs under a slight fat layer
  • Overhead view: A defined waist should be visible between ribs and hips
  • Side profile: The abdomen should tuck upward behind the last rib

Overweight Thai Ridgebacks face higher risks of Dermoid Sinus, joint problems, and shortened lifespan. Even for a medium-sized breed, excess weight significantly impacts joint health and overall wellbeing. Work with your vet to adjust feeding and exercise if needed.

Feeding Recommendation

Adult Thai Ridgebacks (35–75 lbs) typically need 0.5 to 1.5 cups of high-quality dry food per day, divided into two meals. A formula suited to medium breeds provides appropriate nutrient density. Needs vigorous daily exercise and mental stimulation; their athletic ability includes exceptional jumping, so six-foot or higher fencing is essential.—adjust portions based on activity level. Budget $67–102/month for food costs.

Three quick checks for your Thai Ridgeback: (1) Feel the ribs–they should be easily palpable under a thin fat layer. (2) View from above–there should be a visible waist behind the ribs. (3) Side profile–the abdomen should tuck up. Target weight: 35–75 lbs. Their short and smooth coat can make visual assessment harder, so hands-on rib checks are especially important. Consult your vet for a body condition score.
Start with the food label's guidelines for your puppy's current weight and adjust based on body condition. Thai Ridgeback puppies should eat 3–4 meals daily until 6 months, then transition to twice daily. Given the breed's predisposition to Dermoid Sinus, your vet may recommend specific dietary considerations. Target adult weight is 35–75 lbs (35–75 for males, 29–66 for females).
Poor weight gain in a Thai Ridgeback puppy warrants a vet visit. For a breed that should reach 35–75 lbs at maturity, slow growth can signal parasites (very common in puppies), underfeeding, food intolerance, or illness. Regular weigh-ins help track progress objectively. Your vet will likely run a fecal test and blood work.
