Reading Pet Supplement Labels: What Ingredients Actually Mean
A label-decoding guide so you know exactly what you’re giving your pet.
Active vs inactive
Actives drive the intended effect; inactives include flavors and carriers. Both should be transparent.
Per-serving math
Check mg per chew and servings per day; adjust by weight as the label directs.
Quality signals
Lot numbers, NASC-style seals, and clear contact info are good signs of accountability.
Red flags
Avoid artificial sweeteners like xylitol, vague proprietary blends without amounts, and mega-doses beyond guidelines.
Frequently asked questions
Are human-grade claims meaningful?
They can be positive, but dosing and formulation must still be pet-specific.
How to check third-party testing?
Look for seals or published test summaries; contact the brand if unclear.
How to adjust dose by weight?
Follow label ranges; when in doubt, ask your vet for exact mg/kg guidance.
