Echinacea-C™ for Dogs by Standard Process: Immune Causes, Care, Prevention
The following information is a summary and review based on Dr. Candy's professional experience and recommendations. Any summary or statement has not been provided nor influenced by the manufacturer.
When I support a dog’s immune system, I always start with nutrition. Echinacea-C™ by Standard Process is one of the whole food supplements I reach for when a dog needs extra immune or respiratory support.
This formula combines echinacea with a natural vitamin C complex from whole foods. It is designed to help the immune system respond appropriately, not overstimulate it. That distinction matters, especially for dogs dealing with infection, stress, or repeated illness.

What Echinacea-C™ Is and Why I Use It
Echinacea-C™ is a daily immune support supplement made from whole plant ingredients. It includes two forms of echinacea along with buckwheat and other whole food sources of vitamin C.
Echinacea has been used for centuries in traditional medicine. In veterinary practice, it is valued for helping the immune system respond more efficiently during times of challenge.
Standard Process has been producing whole food supplements since 1929. Their formulas are grown, processed, and tested with consistency, which is why I trust them in my own recommendations for dogs.
Key Benefits of Echinacea-C™ for Dogs
Immune System Support
A healthy immune system helps dogs fight infections and recover more efficiently. Echinacea-C™ supports immune cell activity, including white blood cells that help recognize and respond to pathogens.
I often use this supplement when a dog is actively fighting infection or dealing with repeated immune stress.
Research has shown echinacea plants contain antioxidant and antibacterial compounds that support immune response pathways.
Respiratory Health Support
The immune and respiratory systems are closely linked. When immune defenses are overwhelmed, the respiratory tract is often affected.
Echinacea-C™ helps support healthy airways and immune activity in the lungs. This can be helpful for dogs prone to coughing, kennel cough, or upper respiratory infections.
Studies suggest echinacea may help support clearance of respiratory infections and modulate inflammation in airway tissues.
Skin and Tissue Support
Vitamin C plays a role in collagen formation. Collagen supports skin integrity, connective tissue, and healing.
By providing a whole food vitamin C complex, Echinacea-C™ supports skin resilience while also contributing to overall vitality.
Ingredients That Make Echinacea-C™ Effective
Echinacea-C™ works because of how its ingredients work together, not because of high isolated doses.
Echinacea angustifolia and Echinacea purpurea (root)
These two echinacea species support immune signaling and white blood cell activity. They also help regulate inflammation so the immune response stays balanced.
Organic Buckwheat
Buckwheat provides a natural vitamin C complex along with vitamin E and plant antioxidants. Vitamin C supports immune defense, collagen production, and cellular protection.
Whole Food Vitamin C Sources
Rose hips and acerola are included to supply antioxidant vitamin C in a form the body recognizes and uses efficiently.
When I Commonly Recommend Echinacea-C™ for Dogs
I use Echinacea-C™ as part of a broader plan, not as a standalone cure. It is most helpful during active immune challenges or periods of high stress.
Common situations include immune suppression or frequent illness, kennel cough or upper respiratory infections, pneumonia support alongside veterinary care, chronic ear infections, papilloma virus lesions, parvo recovery support, demodectic or sarcoptic mange, giardia or recurring intestinal parasites.
This supplement supports the immune system while the body does the work of healing.

How Echinacea-C™ Works in the Body
Echinacea helps activate immune cells, including white blood cells, while also calming excessive inflammation. This balance is important for effective immune defense.
Vitamin C supports connective tissue, antioxidant protection, and immune signaling. Together, these nutrients help the body respond efficiently without unnecessary strain.
Dosage and Administration for Dogs
Correct dosing matters. These are general guidelines I use in practice.
|
Dog Size
|
Dosage
|
|---|---|
|
Small Dogs 1-20lbs
|
2 tablets daily
|
|
Medium Dogs 21-50lbs
|
3 tablets daily
|
|
Large Dogs 51+ lbs
|
4 tablets daily
|
Echinacea-C™ can be given with meals. Many dogs take the tablets willingly. If needed, the tablet can be mixed into food or hidden in a small treat.
When a dog is actively fighting an infection, twice-daily use is important for consistent immune support.
Safety and Possible Side Effects
Echinacea-C™ is generally well tolerated. Mild digestive upset, such as soft stool, can occur when starting any new supplement.
Do not use in pregnant or nursing dogs due to limited safety data. Use caution if your dog has a known allergy to plants in the daisy family.
If your dog is on medication or has a complex medical condition, I recommend discussing supplement use with your veterinarian.
