Chesapeake Bay Retriever: 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.
Chesapeake Bay Retriever and chocolate: how much is dangerous?
Typical adult weight: 25–36.5 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 |
|---|---|---|---|

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.
