Supporting Dogs with Colour Dilution Alopecia Through Nutrition
Colour Dilution Alopecia (CDA) is an inherited skin and coat condition seen in some dogs with dilute coat colours, including blue, silver and fawn. It is associated with abnormal clumping of melanin within the hair shaft and follicles, which can contribute to brittle hair, hair loss, dry or flaky skin and, in some dogs, secondary skin infections.
CDA is a genetic condition, so nutrition cannot "cure" the underlying cause. However, supporting the skin, hair and connective tissue with appropriate nutrition may help provide the building blocks the body needs to maintain healthy tissue.
Why collagen?
Collagen is one of the major structural proteins found in the skin and connective tissues. It is particularly rich in amino acids including glycine, proline and hydroxyproline.
A recent review examining amino-acid metabolism in canine and feline skin and hair highlights the importance of adequate amino acids for maintaining healthy skin and hair structures.
Bovine collagen peptides provide a concentrated source of these collagen-associated amino acids in an easily incorporated nutritional form.
Research has also investigated the use of hydrolysed bovine collagen in dogs, with one canine study finding improved early epithelialisation during wound healing. While this study was looking at topical collagen rather than oral supplementation, it provides supporting evidence for collagen's biological role in canine skin and tissue repair.
The role of vitamin C
Vitamin C is involved in the formation and maintenance of collagen. It also has antioxidant functions and plays a role in normal tissue repair.
This makes vitamin C a logical nutritional partner to collagen when the goal is supporting healthy connective tissue.
And MSM?
MSM (methylsulfonylmethane) is an organic sulphur compound. Sulphur is involved in a number of biological processes, including those associated with connective tissue and structural proteins.
Together, collagen peptides, vitamin C and MSM provide complementary nutritional support for the body's normal connective-tissue processes.
What does this mean for CDA?
The aim isn't to claim that collagen, vitamin C or MSM can reverse the genetic cause of CDA. They can't.
Instead, the focus is on supporting the tissues affected by the condition — providing nutritional building blocks for skin and connective tissue and helping maintain the overall health and condition of the skin and coat.
We've seen remarkable real-world results using Regen Remedy in dogs affected by colour dilution alopecia, particularly in the condition and appearance of the skin and coat.
Every dog is different, and CDA can vary considerably between individuals. Veterinary assessment is important, particularly where there is significant hair loss, inflammation, itching or recurrent skin infection.
The Regen Remedy
The Regen Remedy combines:
Bovine collagen peptides + MSM + Vitamin C to provide targeted nutritional support for skin, connective tissue, recovery and overall tissue health.
It can be used as part of a broader nutritional approach rather than as a replacement for veterinary care.

For whole foods that can add benefits to CDA, you can add things like chicken/ poultry feet, brains and heads, salmon frame, sardines, anchovies, fish products, skins with hair, or fleece removed. Skin is very high in collagen.
