Senior Stage Overview

Decreased activity and weight gain — After age 7, the basal metabolic rate slows and activity decreases, making rapid weight gain possible. Hypothyroidism compounds this challenge.

Increased hypothyroidism risk — Hypothyroidism is relatively common in native Korean breeds like the Sapsali. Annual T4 blood tests from age 7 are the key to early detection.

Joint and kidney dual care — Hip dysplasia progression and kidney function decline can appear simultaneously. A senior food with glucosamine and low phosphorus addresses both at once.

Sarcopenia prevention — Muscle loss in senior dogs leads to reduced mobility and quality of life. If kidney function is normal, do not reduce protein — keep it at ≥ 18%.

Key Nutrition Points

checkLow-calorie, high-protein senior food — maintain muscle mass while managing weight. Do not reduce protein if kidney function is normal; keep protein ≥ 18% to prevent sarcopenia.
checkGlucosamine and chondroitin plus low phosphorus — simultaneously support senior joint cartilage and reduce kidney burden. Annual blood tests (BUN and creatinine) recommended.
checkMaintain omega-3 (EPA+DHA), zinc, and biotin — long-coat care continues into the senior years. As the skin barrier weakens with age, omega-3 becomes even more important.
checkIncreased hypothyroidism risk — Dixon et al. (1999): key signs are unexplained weight gain, symmetrical hair loss, and lethargy. Annual T4 blood test recommended from age 7.
checkIncrease wet food ratio if mobility declines — muscle loss accelerates if the dog stops eating. Mix dry and wet food to improve palatability.
checkDHA, MCT, and vitamin E — check for these cognitive-support nutrients if signs of Canine Cognitive Dysfunction Syndrome (CDS) appear.

Calorie & Portion Guide by Weight

WeightDaily Calorie TargetReference Portion (400 kcal/100 g)
17 kg~705–825 kcal/day~176–206 g
20 kg~795–930 kcal/day~199–233 g

27 kg~995–1,160 kcal/day~249–290 g

Based on NRC (2006) RER × 1.2–1.4 for neutered seniors. If hypothyroidism is diagnosed, recalibrate calories with your vet.

Health Management Checklist

check_circleStrengthen weight management — activity decreases with age, making weight gain rapid. Monthly weigh-ins, target BCS 3/5. Excess weight worsens joints, thyroid, and kidneys simultaneously.
check_circleHypothyroidism monitoring — annual T4 blood test from age 7. See a vet immediately if unexplained weight gain, symmetrical hair loss, or lethargy appears.
check_circleJoint and mobility support — glucosamine- and chondroitin-enriched senior food or a dedicated joint supplement. Lay mats on slippery floors and make environmental adjustments.
check_circleKidney function monitoring — annual blood tests (BUN and creatinine). If kidney function declines, transition to a low-phosphorus prescription diet under veterinary guidance.
check_circleWatch for cognitive changes — if disorientation, changed sleep patterns, or reduced responsiveness appear, consider MCT, DHA, and vitamin E enriched senior food or cognitive supplements.

Food Selection Checklist

  • checkMedium-to-large breed senior formula (low-calorie, high-protein design)
  • checkOmega-3 (EPA+DHA) listed — continued skin barrier and long-coat support in senior years
  • checkGlucosamine and chondroitin — senior joint cartilage protection
  • checkLow phosphorus — kidney protection in seniors
  • checkProtein ≥ 18% — prevention of senior sarcopenia
  • checkDHA, taurine, and vitamin E — support for ageing eyes and brain function

자주 묻는 질문

Q. When should I switch a Sapsali to senior food?

The Sapsali is generally considered a senior from age 7. However, ageing speed varies between individuals, so switching based on symptoms rather than age alone is more accurate. If the dog is gradually gaining weight, becoming less active, or showing signs of joint discomfort, consider transitioning to a senior food. Ideally, the decision should be based on annual vet check results covering thyroid, kidney, and liver values.

Q. Should I reduce protein for a senior Sapsali?

For a Sapsali senior with normal kidney function, reducing protein is not recommended. On the contrary, muscle loss (sarcopenia) can progress rapidly in senior dogs, so maintaining protein at ≥ 18% is advised. Protein restriction is only warranted when kidney function decline is confirmed by blood tests, and even then the transition to a low-protein prescription food should be done under veterinary guidance.

Q. How is hypothyroidism in a senior Sapsali managed?

A confirmed hypothyroidism diagnosis requires veterinary prescription hormone replacement therapy (levothyroxine). From a dietary standpoint, manage weight with a low-calorie, high-protein food and keep selenium and iodine within normal ranges with an AAFCO-compliant food. Even after thyroid treatment, body weight tends to increase easily, so continuing bi-weekly weigh-ins is important.

Q. How does coat care change for a senior Sapsali?

As the dog ages, the skin barrier weakens and coat resilience may decline. Choose a senior food that maintains omega-3, zinc, and biotin content, and consider adding a fish oil supplement. Keep the grooming frequency the same as adulthood — 2–3 times per week — but use a softer brush as the skin may become more sensitive. If skin changes appear (hair loss, redness, increased dandruff), check for hypothyroidism first.
