Overview
An unflavored liquid fish oil supplement delivering 1380mg of omega-3 per teaspoon, formulated for large to very large dogs.
This is a liquid fish oil rather than a chew or capsule, dosed by the teaspoon and sized for large to very large breed dogs specifically. The 1380mg omega-3 concentration per teaspoon is on the higher end for pet fish oils, which typically means less volume is needed per dose relative to weaker formulas. Being unflavored, it is meant to be mixed into food rather than fed on its own.
- 1380mg omega-3 per teaspoon
- 16oz liquid bottle
- Unflavored, mixes into food
- Formulated for large to very large dogs
Who it's for
Owners of large or very large dogs looking to support skin, coat, heart or immune health with a liquid omega-3. Less suited to small dogs, where the concentration and dosing size are calibrated for bigger body weights.
Strengths and trade-offs
Drawn from this product's published specifications.
- High concentration at 1380mg omega-3 per teaspoon
- Unflavored liquid mixes easily into regular meals
- 16oz bottle sized for large dogs' higher dosing needs
- Liquid format allows adjustable dosing by weight
- Formulated for large to very large dogs, not sized for small breeds
- Contains fish, unsuitable for dogs with fish allergies
Performance notes
As a liquid rather than a soft chew, dosing is measured by teaspoon and mixed into the dog's regular food, allowing more precise amount control than a fixed-dose chew. Fish is listed as an allergen source, so it is not suited to dogs with a known fish sensitivity.
