How do I tell if my dog has rod-cone dysplasia 1?

RCD1 symptoms begin early in a puppy's life, with the first signs typically appearing between 6 to 8 weeks of age. The initial symptom is night blindness, as rod cells responsible for low-light vision degenerate first. Affected puppies may seem clumsy or hesitant in dim lighting conditions. The PDE6B gene mutation responsible for this condition can be identified with a DNA test. Getting your vet involved now is important. If you want to talk it through first, our vets can help you understand what questions to ask and what tests might be useful.
