Icthyosis is a genetic skin disorder that is common in several breeds, including one of the most popular -- the Golden Retriever - as well as the American Bulldog. The University of Pennsylvania is conducting genetic studies of the genes involved in passing this genetic trait and has developed, at least preliminarily, a test to identify if a dog or bitch carries the affected gene.  While the test is not yet available commercially, some participants in the study have been able to receive test results concerning their dogs. The test will hopefully be available to all American Bulldog breeders, or potential breeders, in the near future. Through careful breeding practices,  and ethical breeder communication, this skin disorder can be avoided.

Ichthyosis does not kill dogs, but it can make their life quite uncomfortable. Ichthyosis is noticible soon after birth.  The puppies skin appears wrinkly and flaky -- like a child’s snow globe, the skin flakes fall. As the dog matures, the condition may recede somewhat or get worse. The dog will never recover, and weekly, if not daily, bathing and application of oils to the skin are required to keep the dog comfortable. The dog may be very itchy, and injure its skin by scratching and chewing and will be prone to “hot spots.”  

Most breeders will cull affected puppies at birth. Others may not recognize the problem and will still sell the affected animals to unwary purchasers. Some breeders will continue to repeat breedings that have produced affected animals, and will not inform their puppy purchasers of their puppy’s genetic disposition. Puppies that may be carriers of the gene that are placed in spay/neuter pet homes are of no concern. But without disclosure, people who may plan to breed their pup in the future may continue to perpetuate the disorder and produce affected animals.

For more information concerning Icthyosis in canines, contact the University of Pennsylvania, Dr. Margaret Casal, DVM or give us a call for contact information. The University is still accepting samples for its genetic research.  Participants in the study will receive test results free of charge.  Canine genetic studies help scientists and researchers to understand human genetic disorders, as well, so participating in these types of research projects can provide valuable information for more than just a specific dog or breeding program.
