Ensuring the Omega-3 Fatty Acids in Homemade Dog Food: Natural Sources and Safe Feeding

If you’re making your dog’s food at home, you’re already doing more than most people. But here’s the truth many well-meaning owners miss: Omega-3 is one of the most commonly under-supplied nutrients in homemade dog diets.

Omega-3 fatty acids are anti-inflammatory fats essential for brain function, joint health, skin and coat condition, and heart health. Low Omega-3 level contribute to inflammation, poor coat quality, and cardiovascular issues.

This cluster post expands on the Omega-3 section of the pillar blog, providing detailed guidance on safe natural sources, daily amounts by dog size, and preparation considerations.

What Is Omega-3 — And Why Should You Care?

Omega-3 fats are anti-inflammatory fats.

They support:

• Brain health (especially puppies and seniors)

• Joint mobility

• Skin and coat condition

• Heart health

• Immune balance

Most homemade diets — especially those heavy in chicken — are naturally high in Omega-6 fats. Omega-6 isn’t “bad,” but without enough Omega-3 to balance it, inflammation creeps up, and inflammation is at the root of most chronic issues.

Why Omega-3s Matter

There are two different types of Omega-3.

• EPA & DHA (from marine sources): Reduce inflammation, support heart and joint health, and aid cognitive function.

• ALA (plant-based, e.g., flax, chia): Converts to EPA/DHA but poorly absorbed in dogs. Marine sources are preferred.

So if you’re relying on flaxseed alone, you’re probably not correcting the imbalance. In the Ramses approach, marine-based EPA and DHA are the priority.

Deficiency Signs:

• Dull, dry, or brittle coat

• Skin irritation or dandruff

• Joint stiffness or inflammation

• Poor cognitive function in seniors

  
  

Option 1. The Simple, Practical Solution: Feed Oily Fish

No complicated supplements. No expensive capsules. No chemistry. You need small oily fish. The best choices are:

• Sardines (in water, no salt)

• Mackerel

• Anchovies

• Wild salmon (when available)

  
  

Small fish are preferred because they’re lower in heavy metals.

How Much Oily Fresh Fish Should You Feed?

Here’s a simple weekly guide for maintenance feeding:

Aim for oily fish to make up roughly:

  1. 5–10% of your dog’s total weekly meat intake

2. That’s enough to balance fats without overdoing it.

3. An alternative is tinned sardines.

4. Most standard tins of sardines are: 90–120g (3–4.2 oz) drained weight

So here’s how that translates:

Dog Size	Weekly Amount	What That Means Practically
Miniature	30–50g (1–1.8 oz)	About ⅓–½ of a small tin per week
Small	60–100g (2–3.5 oz)	Roughly ½–1 tin per week
Medium	120–200g (4–7 oz)	1–2 tins per week
Large	250–400g (9–14 oz)	2–4 tins per week
Giant	400g+ (14 oz+)	4+ tins per week

You can split this across the week. For example:

• A medium dog might get half a tin on Tuesday and half a tin on Friday.

• A large dog might get one full tin twice a week.

No precision scales needed. Just simple, practical feeding.

Option 2: Specific fish oil: 

Top Recommended Marine Sources for Dogs

Source	Benefits	Notes / Safety Considerations
Anchovy Oil	High EPA/DHA, low contaminants	Small fish, safer for long-term feeding
Sardine Oil	Rich in Omega-3s and protein	Naturally low in mercury
Krill Oil	Highly bioavailable EPA/DHA	Low in heavy metals, antioxidant-rich
Wild Salmon Oil	Nutrient-rich, supports skin and immunity	Source carefully for purity
Cod Liver Oil	Traditional source of Omega-3s	Contains Vitamin A/D; balance to avoid toxicity

Key Safety Guidelines:

• Always use dog-specific or pet-safe marine oils, not generic “fish oil”.

• Prefer oils that are third-party tested for purity and heavy metals.

• Look for NASC-certified products when possible.

• Store oils in glass containers to prevent chemical leaching.

• When adding fish oil, supplement with vitamin E to prevent oxidative stress.

Practical Daily Guide for Specific Fish/Oil by Dog Size

Dog Size	Anchovy/Sardine Oil (ml/tsp)	Wild Salmon Oil (ml / tsp)
Miniature	0.25–0.5 ml / 1/16–1/8 tsp	0.25–0.5 ml / 1/16–1/8 tsp
Small	0.5–1 ml / 1/8–1/4 tsp	0.5–1 ml / 1/8–1/4 tsp
Medium	1–2 ml / 1/4–1/2 tsp	1–2 ml / 1/4–1/2 tsp
Large	2–3 ml / 1/2–3/4 tsp	2–3 ml / 1/2–3/4 tsp
Giant	3–5 ml / 3/4–1 tsp	3–5 ml / 3/4–1 tsp

Practical Notes:

• Use measured spoons or syringes for accuracy.

• Rotate oils with small oily fish (sardines, mackerel, anchovies) 1–2 times per week if preferred.

• Avoid large predator fish (tuna, swordfish) due to mercury risk.

Common Mistakes We See

❌ Using flax oil instead of fish

❌ Feeding chicken as the main protein without balancing fats

❌ Relying entirely on fish oil capsules

❌ Ignoring fat balance completely

Homemade food is not just about protein and vegetables. Fat balance matters — a lot. Remember Oily fish is preferred but oil supplements may help if:

·       Your dog refuses fish

·       There is a medical condition requiring higher EPA/DHA levels

·       You’re managing diagnosed arthritis or chronic inflammation

Even then, they should complement — not replace — a balanced food foundation.

Life Stage Considerations

• Puppies: EPA/DHA critical for brain and eye development. Include marine oily fish or oils in small, safe amounts.

  
  

• Adult Dogs: Maintain healthy skin, coat, and joints with regular oily fish or marine oil supplementation.

  
  

• Senior Dogs: Support joint mobility, cognitive function, and cardiovascular health.

  
  

Practical Tips for Omega-3 Oil Supplementation

• Stick to dog-specific products and measured portions.

• Rotate fish and marine oils for variety and safety.

• Monitor coat, skin, and mobility as indicators of Omega-3 status.

• Pair with a balanced diet including other fats, proteins, and vitamins to optimize absorption.

The Choice Is Yours

Homemade feeding is about responsibility. It’s about stepping away from processed convenience and choosing real food. But real food only works when it’s balanced.

Omega-3 isn’t a trendy add-on. It isn’t a marketing buzzword. It’s a foundational nutrient your dog depends on every single day. If you’re feeding homemade and not intentionally including oily fish, you’re not finished yet.

The solution isn’t complicated: Add the sardines, Add the mackerel and feed with purpose. Because when you balance fats properly, you don’t just improve coat shine. You support joints, reduce inflammation, strengthen resilience and build long-term health.
