Breed 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.

Komondor and chocolate: how much is dangerous?

Typical adult weight: 40–60 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
40 kg	400 g signs 800 g severe	100 g signs 200 g severe	57 g signs 114 g severe
60 kg	600 g signs 1200 g severe	150 g signs 300 g severe	86 g signs 171 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.
