How to Read a Pet Supplement Label Without Getting Fooled
Two products can list identical ingredients and deliver completely different results. The difference is almost always in the amounts, the sourcing, and what isn't printed on the front of the bag.
Check the amounts, not the ingredient list
A 'proprietary blend' means the manufacturer doesn't have to tell you how much of each ingredient is in the mix. If the beneficial ingredient is listed last in a blend, it may be present in trace amounts.
Match the dose to your pet's weight
Many labels quote the serving for a mid-size dog. Cats and small breeds often need a fraction of that, and large breeds need more than the front label suggests. Always read the full dosing chart on the back.
Green flags worth paying for
When comparing two similar products, these tip the decision:
- Named ingredient sources rather than generic category names
- Third-party testing or batch numbers
- CFU counts and strain names for probiotics
- Short ingredient lists with minimal fillers and no added sugars
- Clear guidance on how long to run the product before evaluating
