How To Read A Dog Supplement Label
Active vs. other ingredients
Active ingredients are the ones the product is built around, usually listed with an amount. Other ingredients carry, preserve or flavor the formula. Both matter, especially if your dog has food sensitivities.
What counts as a "serving"
A serving might be a chew, a scoop or a number of mL. Check what the label means, then multiply by your dog's daily serving to see what they'd actually get.
Ingredient sources
Skin and coat formulas often use fish, bovine or poultry-derived ingredients. The source matters if your dog has sensitivities.
Lot number and certificate of analysis
A lot number makes it possible to trace a product. A certificate of analysis shows what a lab measured in that batch.
The claims
Products like these aren't approved to diagnose, treat, cure or prevent disease. Claims that they do are a reason for caution, and a reason to ask your vet.
