Things to keep an eye on

MDR1 Gene Mutation

high

This genetic mutation causes sensitivity to certain common medications, which can lead to adverse reactions. It is important to confirm your dog's status with your veterinarian before administering any new drugs.

Consult your veterinarian about genetic testing to identify medication sensitivities early.

Collie Eye Anomaly (CEA)

moderate

CEA is an inherited condition that affects the development of the eye, potentially impacting vision. Routine eye examinations help monitor for any changes in ocular health.

Schedule annual eye exams with your veterinarian to monitor ocular development.

Hip Dysplasia

moderate

This is a developmental condition where the hip joint does not fit together perfectly, potentially leading to discomfort over time. Maintaining a healthy weight helps reduce stress on the joints.

Keep your dog at a healthy weight to minimize unnecessary pressure on the hip joints.

General patterns, not a diagnosis — always check with your vet.
