Buying Guide

Match supplement to specific condition

Choose formulations aimed at the issue you’re addressing — liver supplements with SAMe and silybin for hepatic support, collagen/NAD+ precursors for senior joint and cellular support, or omega and biotin blends for skin and coat

Check active ingredient dosages

Look for products that list amounts of key actives (e.g., SAMe, silybin, collagen peptides) so you can compare potency and consult your veterinarian on appropriate dosing

Prefer specialized veterinary brands

Veterinary-focused manufacturers and lab-grade formulas often provide clearer ingredient sourcing and dosing, useful when evaluating liver-focused or clinical supplements

Consider format and palatability

Soft chews and flavored formulations can improve adherence for picky dogs, while powder or capsule forms may offer flexible dosing for larger or smaller pets

Assess safety and interactions

Review ingredient lists for potential interactions with prescription meds and check for added fillers or allergens; discuss new supplements with your veterinarian, especially for dogs with chronic conditions
