The dog supplement market in the UK is now worth over £200 million annually. Much of it is spent on products with little to no scientific backing. Here's a clear-eyed look at what's worth your money.
Fish Oil (Omega-3) — Strong Evidence
The evidence base for omega-3 supplementation in dogs is solid. Benefits include reduced joint inflammation, improved coat condition, and potential cardiovascular benefits. Dose: 50–75 mg combined EPA+DHA per kg of body weight per day. Source: fish oil rather than flaxseed (dogs convert ALA to EPA/DHA poorly).
Glucosamine/Chondroitin — Moderate Evidence
Evidence for joint protection in dogs is mixed, but several studies show benefit in dogs with existing osteoarthritis. More useful as a management tool than a preventive one. Best given as part of a quality joint diet rather than standalone supplements.
Probiotics — Emerging Evidence
Canine-specific probiotic strains (not human formulas) show promise for gut health, particularly after antibiotic treatment or in dogs with chronic diarrhoea. Saccharomyces boulardii and Lactobacillus acidophilus have the strongest supporting data.
Not Worth It
- Most "calming supplements" — evidence is weak, often placebo-level
- Antler supplements — no meaningful evidence
- Most "detox" or "cleanse" products — no credible mechanism or evidence
