What’s Really in Your Dog’s Omega-3 Supplement? A Side-by-Side Ingredient Showdown
When it comes to choosing a supplement like salmon oil or OMEGA-3s for dogs, most pet parents want two things: quality ingredients and real results. But with so many products on the market, Welactin, Bark&Spark, and others, it can be tough to tell what’s actually good… and what’s just good marketing.
That’s where we come in. Today, we’re breaking down popular canine Omega-3 soft chews supplements, ingredient by ingredient, so you can see why OMG!!! Omegas is earning its spot at the top of every canine OMEGA 3 list.

What to Look For?
When choosing an omega-3 supplement for your dog, labels should be clear on the amounts of EPA and DHA per chew. These are the powerful, marine-based omega-3s that support your dog’s skin, coat, joints, and heart. Look for ingredients sourced from fish like salmon or anchovy (not plants – a.k.a. ALA), a label that shows the exact omega content per serving, and no unnecessary fillers. A quality supplement should deliver real benefits with just one easy dose per day for the average size dog.

A quality Omega-3 supplement for your dog should check all the boxes:
Effective Dosage 10 mg of DHA+EPA per lb of body weight (A 25 lb dog needs about 250 mg of combined EPA + DHA daily)
Easy to use dosage instructions (i.e 1 Bernies is equal to 10 Bark and Sparks for the same DHA+EPA dosage)
All Natural Ingredients
Clean Labels with clear math
Let’s Take a Look at Three Omega 3 Chews for Dogs:
Welactin Omega 3 for Dogs: Trusted but What’s Missing?
- Fish Oil (255 mg EPA+DHA per chew)
- Added Multivitamins & Beta Glucans
- Fillers
❓Why pet parents choose it: Welactin is a well-known option that combines omega-3s with added nutrients to support overall wellness.
Something to consider: It delivers a good amount of EPA and DHA, delivering on serving size for full omega-3 benefits, but, it comes with a few additives. Refer to our label chart for more information on choosing the best ingredients for your dog. If you’re aiming for maximum support in one chew, keep reading.

Bark&Spark: Volume versus. Value
- Salmon Oil (27 mg EPA+DHA per chew)
- Vegetable Oil, Flaxseed, and Fillers
- Maltodextrin, Sorbic Acid (chemical preservative)
❓Why some pet parents like it: Bark&Spark offers a generous count of chews per container.
Something to consider: The omega-3 content per chew is on the lower side, so dogs may need multiple chews per day to reach an effective dose of EPA/DHA.

OMG!!! Omegas 5x: Big Benefits in One Little Chew
- Fish Oil (267 mg EPA+DHA per chew)
- No Flaxseed, No Fillers, No Artificial Preservatives
- Naturally preserved with Vitamin E
❓Why pet parents love it: OMG !!! Omegas delivers a full daily dose of EPA and DHA in just one tasty chew. Plus, they are made with clean, marine-based ingredients dogs crave.
You get 90 full-strength servings per jar, no measuring, no mess, and no guesswork. Just real omega-3 power, every day.

Here’s How They Compare
Popular ≠ Potent: A Closer Look at Amazon’s Top-Ranked Omega-3 Soft Chew
If you’ve seen Chews climbing the charts on Amazon, you’re not alone, but let’s take a closer look at what’s behind that popularity.
On the surface, a big 180-count jar and a flashy omega-3 number 24,000 mg! Sounds impressive, right?
But here’s the catch: in some cases, the vast majority of that comes from ALA (a plant-based omega-3) from flaxseed, which dogs can’t effectively convert into EPA and DHA (the real omega-3s that do the work). Let’s compare.
