By the common name, some may think “Why are they talking about a fish sickness in a dog grooming blog?” Well, that’s because, despite its common name, Ichthyosis is actually a congenital disease found in dogs where the skin cycle, which is normally around 21 days, may be as short as every three to four days. This leads to excessive shedding of the skin cells and sebum which then leads to what looks like excessive dandruff. This “dandruff” is not only seen on your dog’s coat, but also will be readily seen and accumulated in any area in the home they frequent such as the bed, furniture, their doggy beds, and any non-carpeted room. 

Most cases of ichthyosis are diagnosed by observation. On presentation, there is an excessive amount of flaky, scale-like dander. The more these dogs are groomed, the more you come to realize that the basic problem does not seem to be eliminated. In many of these breeds, in addition to the “fish scaling,” we will also notice black skin, most likely associated with melanin being laid down due to chronic irritation. This irritation can often progress into cracked skin and sores (Westies and Yorkies). In some cases, there will also be thickening in the callus of the nose and footpads, alopecia (Westies), crimpy coat (Cavaliers) and dry eye (Cavaliers). In Goldens, the first signs may be as subtle as increased pigment on the abdomen as a puppy. Some cases will require a biopsy to confirm. For some of the breeds, there is genetic testing available to identify affected individuals and those that are carriers.

In many cases, veterinarians prescribe chlorhexidine which will take care of the infection, but they typically do not recommend a hydrating conditioner. Conditioner is absolutely needed to replace the sebum. Without it, we usually see a relapse of the infection. 

Here at Pooch Pawlor, we have a three-stage bathing technique that greatly reduces the effects of Ichthyosis. This bathing technique not only removes the majority of the flakey, scaley, skin and sebum debris in the coat, it also reduces the occurrence of infections and keeps the skin and coat hydrated. For more information on this bathing technique, please contact us. While we do recommend that your dog come in for this bath every two weeks, we can also work with you on steps you can take at home.
