blue lacy hair lossEver seen a balding blue Lacy? Sometimes it is just a couple patches here and there, other times it affects their entire coat. It is rare, but it does happen due to a genetic disorder called Color Dilution Alopecia (CDA).

Dogs with Color Dilution Alopecia are born with normal coats. Symptoms develop as early as six months or as late as three years. It often starts on the flanks or along the back, but bald spots can occur anywhere and may eventually spread to cover the entire body. Sometimes stiff guard hairs remain over dry skin. Even though dogs with Color Dilution Alopecia can be healthy, they are susceptible to sunburn, windburn and scaly skin. Because the hair follicles are damaged, they are also prone to bacterial skin diseases. But, for the most part, Color Dilution Alopecia is an aesthetic disorder.

This disorder is related to the double dilute gene, dd, that causes the blue coloration in Lacys. Not all blue dogs have Color Dilution Alopecia, and most blue Lacys will never have problems with their coats or skin. (Note: For the sake of this article, blue dogs refer to both traditional blue and tricolor Lacys.) But all dilute dogs, regardless of breed, can develop issues. All Lacys carry the dilution gene. The blues and tris express it more intensely and thus they are at greater risk for alopecia. Read the rest of this entry »
