Best Sardine Dog Food Australia

Pawkeen editorial team | Reviewed by Hazel, BVSc | April 2026

When people think omega-3 for dogs, they think salmon. But sardines actually contain MORE EPA+DHA omega-3 per gram than salmon — and yet sardine-primary dog foods are less common in Australia. This guide compares both proteins head-to-head and ranks the best products for omega-3 delivery specifically.

SARDINE vs SALMON: THE OMEGA-3 COMPARISON

OMEGA-3 CONTENT (EPA + DHA per 100g raw):

  • Sardines: 2.0–2.5g EPA+DHA
  • Atlantic Salmon: 1.8–2.2g EPA+DHA
  • Pacific Salmon: 1.4–1.8g EPA+DHA
  • Mackerel: 2.2–2.8g EPA+DHA (winner)
  • Herring: 1.6–2.0g EPA+DHA

SARDINE ADVANTAGES:

  • Cheaper per gram of omega-3 than salmon
  • Smaller fish = lower mercury accumulation
  • Wild-caught (not farmed) = more predictable omega-3 profile
  • Both EPA and DHA in good ratio

SALMON ADVANTAGES:

  • Higher palatability for most dogs
  • More common in commercial formulas = more product choice
  • Novel protein for most dogs (good for allergies)

CONCLUSION: For pure omega-3 delivery, sardine or mackerel beats salmon. For commercial food choice and palatability, salmon wins.

THE SARDINE HACK FOR ANY DOG

The most cost-effective way to add omega-3 to your dog’s diet:

  • Buy sardines in spring water at Coles or Woolworths ($1.50/95g can)
  • Feed 1/4 can (2-3 sardines) per 10kg body weight 2x per week as a food topper
  • This adds approximately 0.8–1.2g EPA+DHA per serving
  • Total omega-3 cost per week for a 20kg dog: ~$1
  • Comparable to a $40–60/bottle fish oil supplement
  • Dogs love sardines — palatability is nearly universal

LIMITATION: This is not a substitute for a fish-primary food if novel protein benefit is the goal. Use this approach when the goal is omega-3 supplementation specifically.

FAQ

Can I give my dog tinned sardines from the supermarket?

Yes — sardines in spring water (not brine, not oil-packed, not tomato sauce) are safe and beneficial for dogs. Excellent, affordable omega-3 source. Limit to 2–3 times per week as a topper rather than a sole diet.

Is salmon or sardine better for dogs?

Sardines provide marginally more omega-3 per gram and are smaller fish (lower mercury). Salmon has higher palatability. For commercial food, salmon is more widely available in AU. For an affordable supplement, sardines in water are exceptional value.

Can sardines cause diarrhoea in dogs?

New introduction of sardines can cause loose stools in some dogs due to the high fat content. Introduce gradually — start with half a sardine and build up over 1–2 weeks. Dogs with pancreatitis should not be given high-fat fish without vet guidance.
