Canine Multifocal Retinopathy (CMR)
Canine Multifocal Retinopathy (CMR) is a parent Health Watch page. It explains the larger condition family, then points owners to the specific subtype pages that carry different genetics, signs, testing needs, and owner expectations.
Breeds Affected: Brazilian Terrier; Coton de Tuléar; Lapponian Herder
Breed Risk Note: Use the most specific supported subtype on breed pages whenever possible.
The Idiot-Proof Explanation
CMR is an inherited retina problem where spots or blister-like lesions can develop in the back of the eye. Some dogs keep decent vision. Some have retinal changes that matter more. Either way, this is not something an owner can see by staring lovingly into the dog’s face at breakfast.
However, the exact subtype still matters. One label can hide very different inheritance patterns, screening options, severity, cost, and long-term care. Because of that, breed pages should use the most specific supported condition instead of stopping at the umbrella term.
