Quick answer

Our top pick for dog fish oil for tartar control is Zesty Paws Pure Wild Alaskan Salmon Oil. It’s rich in omega-3 fatty acids that help reduce plaque buildup and support overall oral health. For dogs with sensitive stomachs, try Nordic Naturals Omega-3 Pet Soft Gels. If you prefer a liquid option, Grizzly Salmon Oil is a great alternative.

What to consider for Dog Fish Oil For Tartar Control

Fish oil helps control tartar through its anti-inflammatory properties, which can reduce gum inflammation and bacterial growth. Look for oils high in EPA and DHA, ideally from wild-caught fish. The oil should be free from heavy metals and contaminants. Dosage depends on your dog’s weight, so check the label. Some dogs may experience loose stools, so start with a lower dose and gradually increase.

What to look for in a grooming product (shampoo, brush, clipper or wipe)

When choosing a grooming product for tartar control, consider a dog-safe toothpaste or dental wipe with enzymes that break down plaque. For brushes, use a soft-bristled toothbrush designed for dogs. Clippers are not typically used for dental care. Ensure any product is pH-balanced for dogs and free from xylitol, which is toxic. Low noise is important for anxious dogs during tooth brushing.

How we chose these picks

  • Evaluated omega-3 content (EPA and DHA levels) per serving
  • Checked sourcing: wild-caught vs. farmed, sustainability certifications
  • Reviewed purity testing for heavy metals and contaminants
  • Considered palatability and ease of dosing (liquid vs. soft gels)
  • Read customer feedback on effectiveness for dental health
  • Compared price per serving to ensure value
  • Consulted veterinary nutrition guidelines for recommended dosages
  • Never ranked a product higher just because it pays a commission

What to avoid

  • Avoid fish oils with added sugars or artificial flavors
  • Do not use oils from unknown sources that may contain toxins
  • Skip products with low EPA/DHA content, as they may be ineffective
  • Avoid giving too much oil, which can cause diarrhea or pancreatitis
  • Do not rely solely on fish oil; combine with regular brushing and dental chews
