Our verdict
This 32 oz bottle of 100% Pure Fish Oil from Finest For Pets blends wild-caught sardines, anchovies, herring, and mackerel into an unflavored liquid with a detailed omega-3, EPA, and DHA percentage breakdown, and its 4.4 star rating across nearly 4,700 reviews suggests it's a solid, well-established option even without the highest monthly sales volume in this category.
Owners who want a multi-fish-source liquid oil with a labeled percentage breakdown of omega-3, EPA, and DHA rather than a single-species oil.

The overall score is owner satisfaction weighted by how many reviews back it, so a high rating from few reviews counts for less.

Overview
["This liquid fish oil is sourced from a blend of wild-caught sardines, anchovies, herring, and mackerel rather than a single fish species, and the label lists specific minimum percentages of 35 percent omega-3, 18 percent EPA, 12 percent DHA, 7 percent omega-6, and 6 percent omega-9. It's unflavored and sold in a 32 fluid ounce bottle with a flip top cap.", "The brand, Finest For Pets, positions this formula to help support skin, coat, immune, brain, and heart health, with coat, hairballs, heart, and joints called out as specific use areas, and it's formulated for all dog breed sizes rather than one size class.", "At $36.95 for 32 fluid ounces, this is one of the pricier liquid options here, but with 4,731 reviews and a 4.4 star average, it has built a solid reputation, even though its roughly 200 units bought in the past month is more modest than some of the category's top sellers."]
Pros
Multi-fish-source blend of sardines, anchovies, herring, and mackerel
Labeled minimum percentages for omega-3, EPA, and DHA
Unflavored liquid with a flip top cap
Formulated for all dog breed sizes
Strong 4.4 star rating across 4,731 reviews
Cons
Higher price point than many other liquid oils in this category
Lower recent monthly sales volume than top-ranked competitors
Fish allergen means it's not suitable for dogs with a known fish sensitivity
Sourcing from four different small fish species rather than one, and listing minimum percentages for omega-3, EPA, DHA, omega-6, and omega-9, gives this formula more label transparency than products that only name fish oil without a breakdown, which can help owners compare potency more directly across brands.
What buyers say
A 4.4 star average across 4,731 reviews reflects a well-established, generally positive track record, even though its roughly 200 units bought in the past month trails the highest-volume products in this category.
