El Cavalier King Charles Spaniel faces arguably el la mayoría significant breed-health crisis en el dog world: 90% de Cavaliers develop mitral válvula disease (MVD) por age 10, y 50% mostrar evidence de el disease por age 5. El breed's pequeño skull conformation también predisposes 95%+ a Chiari-como malformation, con arriba a 70% developing secundario syringomyelia (fluid-filled cavities en el spinal cord). Estos son no rare edge cases—ellos son el statistical norm para el breed. El UK's Royal Veterinary College tiene identified Cavaliers como having el highest heart disease burden de any breed studied.
Genetic Health Tabla
| Condition | Susceptibility Genes | Incidence Rate | Early Screening |
|---|---|---|---|
| Myxomatous Mitral Válvula Disease (MVD) | Polygenic (multiple QTLs identified en CFA13, CFA14; heritability ~0.6) | 50% por age 5; 90% por age 10 | Annual cardiac auscultation starting en age 1; echocardiogram en age 2, entonces annually; ProBNP blood probar |
| Syringomyelia (SM) / Chiari-como Malformation (CM) | Polygenic (skull/cranial conformation genes; pequeño caudal fossa volume) | 95%+ tener CM en MRI; 50-70% develop SM | MRI screening en 12-24 months (OFA CM/SM scheme); clinical scoring para pain (scratching, vocalization) |
| Episodic Falling Syndrome (EFS) | BCAN (single nucleotide deletion, autosomal recessive) | 5-10% carrier rate | DNA probar (Animal Health Trust/UC Davis); clinical episodes triggered por exercise o excitement |
| Patellar Luxation | Polygenic (pequeño breed association) | 5-8% | Orthopedic physical exam annually |
| Dry Eye (KCS) / Curly Coat Syndrome | FAM83H (autosomal recessive — associated con ambos dry eye y áspero/curly coat) | 3-5% carrier rate | DNA probar; Schirmer tear probar en primero sign de ocular discharge |
Breeding imperative: El MVD breeding guidelines de el Cavalier King Charles Spaniel Club recommend eso breeding dogs debería ser en least 2.5 years viejo con un clear cardiac examination, y ambos parents debería ser heart-clear en age 5+. El UK's BVA/KC CM/SM Scheme grades syringomyelia en un 0-2 scale—breeding de grade 2 dogs es strongly discouraged. MRI screening de breeding stock es el solo way a reduce SM prevalence.
