Pet supplements / best for skin & coat
Best skin & coat supplements, ranked.
Omega-3 fish and salmon oils for skin, coat, and anti-inflammatory support.
Ranked by PetScored composite (evidence quality 30%, active dose 25%, ingredient clarity 15%, safety and manufacturing 15%, value 15%). This ranking is our opinion under a published rubric, not veterinary advice. A product can rank below a peer because its headline active is weakly evidenced or its dose is hidden, even when it is well made.
- Nordic Naturals Omega-3 Pet Soft Gels
The strongest-evidence omega active, fully disclosed in triglyceride form and third-party tested; a partial per-softgel dose for a larger dog keeps it just under the top.
Dogs & catscapsule8.8Strong - Zesty Paws Wild Alaskan Salmon Oil
A disclosed, well-dosed salmon and pollock omega oil, NASC-sealed and inexpensive per day; strong execution puts it near the top. The Feb 2025 Zesty Paws recall covered soft chews, not this oil.
Dogs & catsliquid8.5Strong - Grizzly Salmon Plus Wild Salmon Oil
High disclosed EPA and DHA per pump in natural triglyceride form, NASC-audited, and inexpensive per day; strong execution lands it at the top of Good.
Dogs & catsliquid8.4Good - Nordic Naturals Omega-3 Cat
A triglyceride-form fish oil third-party tested for purity and keyed to the feline skin and coat evidence; a typical cat reaches only a partial share of the studied EPA and DHA dose at the labeled serving, which keeps it Good rather than Strong.
Catsliquid7.8Good - Nutramax Welactin Feline Omega-3
A disclosed fish-oil liquid delivering an EPA and DHA dose near the feline dermatology target, keyed to the cat skin and coat evidence; well made, though the fish-oil form is not stated and the scoop count is derived.
Catsliquid7.8Good - Nutramax Welactin Canine Omega-3 Softgels
A disclosed, well-made omega-3 keyed to the skin and coat claim (a notch below the joint evidence tier); solid execution and value land it Good.
