Shih Tzus were bred for Chinese royalty — and their temperament reflects it. Affectionate, gentle, and surprisingly sturdy for their size, they make wonderful companions. But their flat faces, gorgeous long coats, and genetic predisposition to kidney disease and allergies demand a diet that goes beyond the generic. What a Shih Tzu eats directly impacts their coat quality, breathing comfort, skin health, and how long they live.
Shih Tzus are generally healthy but carry specific health risks that every owner should understand — many of which are directly influenced by diet. Catching these issues early through good nutrition is far easier than treating them once they develop.
Shih Tzus have flat faces and narrow airways. They can overheat rapidly and struggle to breathe during meals. Serve food at room temperature and use a shallow, wide bowl to reduce gulping and overexertion while eating.
Shih Tzus have a higher-than-average risk of hereditary kidney problems, including renal dysplasia. A moderate-protein diet with high-quality, easily digestible protein and good hydration is important from an early age.
Many Shih Tzus are sensitive to common ingredients — particularly chicken, beef, corn, wheat, and soy. Itching, paw-licking, and recurring ear infections often trace back to food. A limited-ingredient diet with a novel protein can transform their skin health.
Those beautiful prominent eyes are prone to corneal ulcers, dry eye, and infections. Antioxidant-rich foods high in lutein and vitamin A support eye health. Tear staining can also be improved through a clean, additive-free diet.
Shih Tzus have low-to-moderate energy needs. They love comfort more than vigorous exercise, and obesity is a real risk — especially in desexed adults. Use a kitchen scale to weigh food accurately and review portions monthly.
| Dog Weight | Life Stage | Daily Calories | Daily Food Amount* |
|---|---|---|---|
| 4 kg | Adult | 210–250 kcal | 115–140g fresh food |
| 5.5 kg | Adult | 270–310 kcal | 150–175g fresh food |
| 7 kg | Adult | 330–380 kcal | 185–210g fresh food |
| 5.5 kg | Senior (8+ yrs) | 240–280 kcal | 135–155g fresh food |
| 5.5 kg | Puppy (under 1yr) | 400–450 kcal | 220–250g fresh food |

⚠️ Kidney Health Note: If your Shih Tzu has been diagnosed with kidney disease, do NOT use this general guide. Kidney-supportive diets require specific protein restriction and phosphorus limits prescribed by your vet. A veterinary nutritionist must design the diet.
The ideal Shih Tzu diet is moderate in protein, high in omega-3 fats for coat and skin, rich in antioxidants, and free from common allergens. Here is what works best — and what frequently causes problems.
This recipe uses duck as the protein base — an excellent choice for the allergy-prone Shih Tzu — paired with coat-supporting omega-3s and antioxidants. Makes enough for a 5.5 kg adult Shih Tzu for one full day (divide into 2 meals).
Shih Tzus are not naturally big drinkers, and chronic mild dehydration stresses their kidneys over time. Adding unsalted bone broth to meals or switching to a fresh food diet (which has much higher moisture content than kibble) makes a meaningful difference to kidney health across a lifetime.
A Shih Tzu's iconic silky coat is one of the best indicators of diet quality. Dull, dry, or brittle coat? Add oily fish (sardines in spring water) 3 times per week. Excessive shedding or skin flakiness? Consider an elimination diet to find hidden food allergens. The coat usually responds to dietary changes within 4–6 weeks.
Cold food straight from the fridge forces a Shih Tzu to eat quickly — and these dogs already have compromised airways that make fast eating uncomfortable. Always allow food to come to room temperature before serving. A wide, shallow bowl also reduces gulping and overexertion at mealtimes.
Shih Tzus have small, crowded mouths and are extremely prone to tartar buildup and gum disease. Fresh food diets help compared to sticky kibble, but regular toothbrushing is still essential. Small pieces of raw carrot 2–3 times per week also provide gentle mechanical cleaning.
🩺 Always consult your vet before making major changes to your Shih Tzu's diet, especially regarding kidney health. Many Shih Tzus are diagnosed with renal dysplasia in early adulthood — if your dog has any kidney concerns, their diet must be designed with a veterinary nutritionist to ensure appropriate protein and phosphorus levels.
