Ruby inherited one copy of the variant we tested for Canine Multifocal Retinopathy, cmr1
This variant should not impact Ruby’s health. This variant is inherited in an autosomal recessive manner, meaning that a dog needs two copies of the variant to show signs of this condition. Ruby is unlikely to develop this condition due to this variant because she only has one copy of the variant.
This result is also important if you decide to breed this dog - to produce the healthiest puppies we recommend genetic testing any potential mates for this condition.
This is a non-progressive retinal disease that, in rare cases, can lead to vision loss. Dogs with larger lesions can suffer from vision loss. CMR is fairly non-progressive; new lesions will typically stop forming by the time a dog is an adult, and some lesions will even regress with time.
cmr1 typically develops in puppies at 11 to 16 weeks and becomes stable by the time they are 1 year old.
CMR is typically only identified when a vet examines the back of the eye which, in dogs with CMR, reveals multiple retinal abnormalities that range from small, flat folds (called "retinal folds") to larger, irregularly edged raised lesions (called "geographic lesions").
Currently, there is no treatment for CMR. However, CMR rarely affects vision to a significant degree, and as we stated, even the associated retinal abnormalities can regress over time.
- Carefully monitoring your dog's vision and seeking a veterinary ophthamologist's opinion if you are concerned are the best ways you can help your affected dog.
