Supplements for Dogs on a Raw Diet: A Comprehensive Guide for Pet Parents

June 13, 2025

Do You Know What Supplements Your Raw-Fed Dog Really Needs?

Feeding your dog a raw diet is a lifestyle choice driven by love and dedication. It’s about giving your canine companion the most natural, unprocessed nourishment possible. But here’s the question every raw-feeding pet parent must ask:

Are you meeting your dog’s complete nutritional needs with just raw meat, bones, and organs?

This is where the conversation around supplements begins. Many dog parents assume that a raw diet alone is enough to provide optimal health. However, without proper supplementation, even the most balanced raw meals can fall short in delivering essential nutrients.

At K9 Vitality, we understand the commitment it takes to raise a healthy, thriving dog on a raw diet. This guide will walk you through everything you need to know about supplements for dogs on a raw diet, why they matter, which ones are essential, and how to use them effectively.

Why Supplements Matter in a Raw Diet

While raw feeding offers a multitude of benefits, shinier coats, better digestion, cleaner teeth, most commercial meats and produce, even organic ones, lack the full spectrum of nutrients that dogs need. Here’s why supplementation is essential:

Modern food lacks nutrient density: Intensive farming and food processing have depleted soil quality and nutrient levels.
Domesticated dogs have different needs: Unlike wild canines, our pets live longer, less stressful lives and need targeted nutritional support.
Raw feeding may omit key micronutrients: Nutrients like manganese, iodine, zinc, and vitamin D are often insufficient in raw diets.

Core Supplements Every Raw-Fed Dog Needs

Let’s break down the most important supplements to consider for dogs on a raw diet:

1. Omega-3 Fatty Acids (EPA/DHA)

Why it’s important: Supports skin, coat, joint health, and cognitive function.
Common sources: Fish oil, krill oil, green-lipped mussel.
Dosage tip: Use high-quality, mercury-free fish oil and store it properly to prevent rancidity.

2. Vitamin E

Why it’s important: Acts as an antioxidant and balances Omega-3 supplementation.
Sources: Wheat germ oil, almond oil, or natural vitamin E supplements.
Note: Dogs supplemented with Omega-3s should also get vitamin E.

3. Iodine

Why it’s important: Essential for thyroid function.
Common deficiency signs: Weight gain, lethargy.
Sources: Kelp or seaweed supplements (must be dosed carefully).

4. Zinc

Why it’s important: Supports the immune system, skin health, and wound healing.
Signs of deficiency: Hair loss, dull coat, recurring infections.
Bioavailable sources: Zinc picolinate or chelated zinc.

5. Manganese

Why it’s important: Crucial for joint integrity, enzyme function.
Natural sources: Green tripe, shellfish, certain nuts (in small amounts).
Supplement form: Manganese gluconate.

6. Vitamin D

Why it’s important: Regulates calcium/phosphorus absorption, supports immune health.
Dogs don’t synthesize enough from sunlight.
Sources: Cod liver oil, vitamin D3 supplements.

7. Probiotics & Digestive Enzymes

Why they’re important: Promote gut health, reduce inflammation, enhance nutrient absorption.
Forms: Powders, capsules, or fermented foods like kefir or raw goat milk.

8. Calcium & Phosphorus Balance

Essential for: Bone health and skeletal structure.
Note: Whole prey model diets usually have this balance, but DIY diets may lack it.

Specialty Supplements Based on Health Needs

Every dog is unique, and their supplement needs may vary depending on age, breed, activity level, and existing health conditions. Here are some specialty additions:

For Senior Dogs

Glucosamine, Chondroitin, MSM: Joint support.
Curcumin (from turmeric): Anti-inflammatory.

For Puppies

Colostrum: Immune boosting.
DHA (from fish oil): Brain development.

For Allergies and Skin Conditions

Quercetin: Natural antihistamine.
Nettle leaf: Anti-inflammatory.

For Detox & Immune Health

Milk thistle: Liver support.
Spirulina: Detoxification and antioxidant-rich.

Signs Your Dog May Be Lacking Key Nutrients

Watch for these common indicators of nutritional deficiencies:

Itchy skin or dry coat
Low energy or lethargy
Frequent ear infections or hot spots
Irregular stool or digestive upset
Poor healing from minor injuries
Behavioral issues or anxiety

How to Choose High-Quality Supplements

Not all supplements are created equal. Follow these tips to ensure you’re giving your dog the best:

Choose brands with third-party testing.
Avoid fillers and synthetic additives.
Prefer natural, bioavailable forms of vitamins/minerals.
Look for transparency in sourcing and ingredients.

Pro Tips for Raw Diet Supplementation

Rotate your supplements: Just like with food, variety reduces over-supplementation risks.
Use a nutrient calculator: Ensure you’re hitting RDAs for your dog’s weight and life stage.
Introduce supplements gradually: Especially probiotics and new oils.
Track changes: Keep a journal of your dog’s energy, coat, stools, and behavior.

Building a Supplement Schedule

Here’s a sample weekly supplementation schedule:

Daily:

Omega-3s
Probiotics
Vitamin E (if giving fish oil)

2–3 times per week:

Kelp powder (for iodine)
Spirulina or greens blend
Glucosamine (for senior dogs)

Weekly:
