Overview
Sold here in the 128 ounce bulk size, Life Line's Wild Alaskan Fish Oil is a liquid omega-3 supplement for dogs and cats, preserved with non-GMO mixed tocopherols rather than synthetic antioxidants.
At 7.7 pounds for the bottle, this is a bulk multi-dog or multi-cat household size rather than a trial bottle, so it suits owners feeding it daily over months. The oil form is added to food rather than given as a capsule, and it is labeled allergen-free. This listing's warranty field lists the product as covered, unlike some pet supplements sold with no warranty at all.
- 128 ounce bulk bottle, salmon and fish flavor
- Non-GMO mixed tocopherols preservation
- Targets dogs and cats
- Ranked #70 in Dog Fish Oil Supplements
Who it's for
Multi-pet households or owners of larger dogs who go through fish oil quickly and want the value of a bulk bottle rather than repurchasing small bottles. Less useful for a single small pet needing only occasional or small doses, where the oil may go rancid before it's used up.
Pros and cons
- Bulk 128 ounce size for long-term daily use
- Preserved with non-GMO mixed tocopherols
- Formulated for both dogs and cats
- Warranty coverage listed on the product
- Large bottle may go rancid before use in a single small pet household
- Oil form requires mixing into food rather than a capsule
Performance notes
Fish oil works cumulatively, supplementing omega-3 intake meal by meal rather than producing an immediate change, so coat and skin benefits typically build over weeks of consistent feeding. The mixed tocopherols slow oxidation of the oil itself once opened, which matters more in a bulk bottle used over a long stretch.
