A PRACTICAL FIRST CHECK
How to check whether a dog food fits your dog
A product page is a starting point, not a complete label. Before you buy, compare what is actually stated with your dog’s life stage and known restrictions—and leave unknown facts as unknown.
Five things to look for on the label
- Species and life stage. Confirm the food is for dogs and covers your dog’s life stage; “all life stages” is a different label claim from “adult.”
- Nutritional adequacy. Check whether the page actually shows a complete-and-balanced statement. A treat or supplemental food should not be mistaken for an everyday diet.
- Ingredients and your dog’s restrictions. Compare the visible ingredients with allergies or intolerances you already know about. A missing ingredient list does not prove a food is safe.
- Guaranteed analysis and moisture. Wet and dry foods are hard to compare from the package percentages alone; moisture matters when comparing nutrients on a dry-matter basis.
- Calories, package size, and price. These details help estimate daily cost. If the page omits them, treat the cost estimate as unavailable, not zero.
Try your first product check
- Install the PetFitly Chrome extension. An account is optional.
- Open an individual dog-food product detail page on Amazon, Chewy, or Petco—not a search, category, or shopping-cart page.
- Open the extension, add your dog’s life stage and weight, and include only restrictions you know are relevant.
- Tap “Check this product.” Read the reasons and missing facts alongside any score; check the package label before relying on the page data.
What a result cannot tell you
PetFitly can flag a declared restriction, a life-stage mismatch, incomplete label information, and other product-level signals. It cannot diagnose an allergy, confirm an unlisted ingredient is absent, or choose a therapeutic diet. If your dog has a medical condition or needs a prescription diet, consult your veterinarian.
Supported pages vary in the facts they publish. If the extension cannot read a page, try another individual product page and verify any extracted information against the physical package.
