Canine Multifocal Retinopathy 2 in Dogs

What does canine multifocal retinopathy 2 look like in dogs?

Dogs experiencing canine multifocal retinopathy 2 will experience fluid buildup in spots where their retina has detached, leading to gray, tan, orange, or pink “blisters” in the back of the eye. Dogs with this disease may have reduced vision. A DNA test for the BEST1 gene can confirm the diagnosis definitively. Schedule a vet visit to get a clear picture. Our vets are also available for a consult if you want guidance before the appointment.

Ongoing ophthalmology visits typically cost $100–$250 every 6–12 months. Home adaptations for vision loss (gates, textured mats, nightlights) are modest one-time costs of $50–$200.

Can canine multifocal retinopathy 2 be prevented through breeding?

Canine Multifocal Retinopathy 2 primarily affects Coton De Tulears. The condition is autosomal recessive, caused by a mutation in the BEST1 gene. DNA testing for the BEST1 gene is available and gives a definitive answer. Affected dogs need two copies of the mutation. Carriers (one copy) are clinically normal. Never breed two carriers — Carrier × Clear pairings produce no affected puppies. Responsible breeders test both parents before any mating. Not sure how to interpret your breeder's health testing? Our vets can break it down for you in a quick consult.
