Rhodesian Ridgeback Deafness

EOAD - Rhodesian Ridgeback Early Onset Adult Deafness

An inherited deafness clinically documented among purebred dogs of the Rhodesian Ridgeback breed. Affected dogs appear to show normal hearing early in post-natal development, but ultimately these dogs lose their hearing, often with complete loss by 1 year of age.

Ridgeback owners have requested access to an interim association test previously offered by ProjectDog, and an interim option has been created through a collaborative data sharing effort with Embark Veterinary.

If your dog has a standard Embark test profile, you have the option to order interim EOAD testing with Projectdog.
