Keto-C® Spray with CeraGuard™ for Dogs and Cats

Keto-C® Spray with CeraGuard™ is a topical antimicrobial skin spray formulated for dogs and cats. It combines 2% Chlorhexidine Gluconate and 1% Ketoconazole with CeraGuard™ skin barrier technology for targeted care between baths.

The no-rinse spray format makes it convenient to apply the formula directly to localized areas of the skin and coat that need regular attention as part of a veterinarian-guided skin care routine.

Chlorhexidine and Ketoconazole Skin Spray

Keto-C® Spray contains two active ingredients commonly used in topical veterinary skin care:

  • Chlorhexidine Gluconate: 2%
  • Ketoconazole: 1%

This combination provides broad-spectrum antimicrobial support and helps manage bacteria and yeast on the skin and coat while supporting routine skin hygiene.

What Is CeraGuard™?

CeraGuard™ is included to complement the antimicrobial ingredients with targeted skin barrier support. The formula contains skin-related lipids and conditioning ingredients that help maintain the skin's natural moisture balance.

CeraGuard™ includes:

  • Ceramide NP
  • Ceramide AP
  • Ceramide EOP
  • Phytosphingosine
  • Cholesterol

These ingredients help support the skin barrier and make the spray suitable for pets that need both antimicrobial care and ongoing moisture support.

Why Are Ceramides Important for the Skin Barrier?

Ceramides are naturally associated with the outer layers of the skin and play an important role in maintaining the skin barrier. A healthy skin barrier helps retain moisture and supports normal protection from environmental exposure.

By combining ceramides with phytosphingosine and cholesterol, Keto-C® Spray with CeraGuard™ provides additional skin barrier support alongside chlorhexidine and ketoconazole.

Between-Bath Skin Care for Dogs and Cats

Full bathing is not always practical when only a small area needs attention. Keto-C® Spray provides a convenient option for targeted topical application between baths.

The spray can be applied directly to localized skin areas according to the product directions or your veterinarian's recommendations. Because it is designed as a no-rinse product, it can remain part of the skin care routine without requiring a complete bath after every application.

When Can a Topical Skin Spray Be Useful?

A topical spray can be useful when specific areas of the skin or coat need more focused care than a full-body shampoo provides. It may also be easier to use on areas that require repeated attention between scheduled baths.

Keto-C® Spray can be incorporated into an ongoing skin care routine alongside other Keto-C® products when recommended for your pet.

Keto-C® Spray vs. Keto-C® Shampoo

Keto-C® Spray and Keto-C® Shampoo provide different application formats for skin and coat care. Shampoo is intended for use during a full bath, while the spray allows targeted application to localized areas between baths.

For pets that need regular skin care, the two formats can be used as complementary parts of the same routine when directed by a veterinarian.

Keto-C® Spray vs. Keto-C® Mousse

Both spray and mousse formats can provide between-bath care without requiring a traditional shampoo application. The difference is primarily in how the product is applied and distributed over the skin and coat.

A spray can be convenient for focused application to a specific area, while a mousse may be useful when a larger section of the coat needs coverage. The appropriate format depends on your pet's skin care needs and your veterinarian's recommendations.

Can Keto-C® Spray Be Used on Dogs and Cats?

Yes. Keto-C® Spray with CeraGuard™ is formulated for use on both dogs and cats.

Use the product according to the label directions and avoid contact with the eyes. If your pet has persistent redness, irritation, hair loss, discomfort, or recurring skin concerns, consult your veterinarian for an evaluation and appropriate care recommendations.
