Fortunately the Dalmatian and Australian Cattle Dog fanciers admit they have a problem and test accordingly. However the breeders of most other breeds are in denial. According to research conducted by Dr George Strain, Louisiana State University (LSU). There are 99 other breeds of dog and 18 breeds of cats, Persian, Himalayan, Siamese and Oriental and more are affected by congenital deafness.

Extract from Dr Strains article “Congenital Deafness”

The disorder is usually associated with pigmentation patterns, where the presence of white in the hair coat increases the likelihood of deafness. Two pigmentation genes in particular are often associated with deafness in dogs: the merle gene (seen in the Collie, Shetland Sheepdog, Dappled Dachshund, Harlequin Great Dane, American Foxhound, Old English Sheepdog, and Norwegian Dunkerhound among others) and the piebald gene (Bull Terrier, Samoyed, Greyhound, Great Pyrenees, Sealyham Terrier, Beagle, Bulldog, Dalmatian, English Setter).
