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.
