Buying Guide

Identify the health need first

Match supplements to your dog's specific concern—liver support, joint health, skin and coat, allergy relief, or general immunity—before comparing brands

Check active ingredients

Look for clinically supported actives like SAM-e and silybin for liver, omega fatty acids for coat, NR or NAD+ precursors for aging support, and proven antihistamine-friendly formulas for allergies

Choose the right form

Soft chews and treats improve compliance, tablets and capsules offer precise dosing, and powders/collagens mix well for picky eaters or multi-dog households

Consider size-specific dosing

Some products are formulated for medium or large dogs with dosing tailored to weight ranges—use those to simplify administration and avoid under- or overdosing

Review ingredient sourcing & transparency

Prefer brands that list active amounts (e.g., SAM-e, silybin, NR, omega-3 EPA/DHA) and disclose third-party testing or veterinary formulation details
