Pekingese: inherited diseases and health
The inherited conditions below have been documented in this breed in published research. That does not mean your dog has them or will get them – but it helps to know the names when you talk to a breeder or a vet.
Conditions this breed is prone to
Veterinary charities list this breed as more likely than others to get these conditions. Read the signs and what to do:
Skin Fold Dermatitis
Cherry Eye
Brachycephalic Obstructive Airway SyndromePekingese and chocolate: how much is dangerous?
Typical adult weight: 5–5.4 kg. Grams of chocolate at which signs can start (20 mg/kg) and at which severe signs are reported (40 mg/kg):
| Dog weight | Milk | Dark 70–85% | Baking / unsweetened |
|---|---|---|---|
| 5 kg | 50 g signs 100 g severe | 12 g signs 25 g severe | 7.1 g signs 14 g severe |
| 5.4 kg | 54 g signs 108 g severe | 14 g signs 27 g severe | 7.7 g signs 15 g severe |
Based on published doses: signs from about 20 mg/kg, severe signs from 40 mg/kg (US FDA, Cortinovis & Caloni 2016, Swedish Poison Information Centre). An estimate, not a diagnosis.

What this list means
- “Documented in the breed” means at least one published case or study – it says nothing about how common the condition is.
- Many of these conditions are rare. A responsible breeder can tell you which health tests the parents have had.
- Where the gene variant is known, a DNA test may exist – ask your vet or the breed club.
- If your pet shows signs of illness, contact your vet. This page cannot tell you whether your pet is ill.
