Quick answer
Our top pick is Zesty Paws Omega Bites for their high omega-3 content and added probiotics that help reduce fishy burps and body odor. For dogs with sensitive stomachs, Nordic Naturals Omega-3 Pet Soft Gels offer a purified, low-odor option. If you prefer a liquid, Grizzly Salmon Oil provides pure wild salmon oil that’s easy to dose.
What to consider for Dog Fish Oil For Smelly Dogs
Not all fish oils are created equal when it comes to odor control. Look for oils that are molecularly distilled to remove heavy metals and impurities, which can contribute to a fishy smell. The source matters: wild-caught fish like salmon, anchovies, and sardines tend to be less odorous than farmed fish. Also consider the form: soft gels often mask odor better than liquids, but liquids can be more cost-effective for large dogs. Probiotics or rosemary extract in the formula can further reduce fishy burps and breath.
What to look for in a grooming product (shampoo, brush, clipper or wipe)
When choosing a grooming product for a smelly dog, consider a shampoo that is pH-balanced for dogs (around 7.0) and contains natural deodorizers like oatmeal, baking soda, or citrus. For brushes, look for bristles that distribute natural oils and remove loose fur without irritating skin. Clippers should have ceramic or titanium blades that stay sharp and run quietly to reduce stress. Wipes are great for spot cleaning between baths; choose alcohol-free, hypoallergenic wipes with aloe or vitamin E. Always test a small area first for sensitivity.

What to avoid
