About Dog Food Labels
Dog Food Labels is a small, free library about one thing: reading a dog food label with confidence - the name rules, the ingredient list, the guaranteed analysis, the adequacy statement, and the claims in between. It is written for ordinary dog households - plain language, no brand rankings, no scare tactics - and it is made by the team behind PawLine, a research-based dog and cat Q&A app. PawLine app, patent pending.
How the guides are written
Each guide builds from the primary regulatory and scientific sources below. Rules and statistics are stated with their denominators and dates, wording stays neutral, and we name the source when a claim matters. We deliberately rank no brands and review no products. These guides are general information, not veterinary advice - your vet knows your dog.
