At a glanceChoose food through nutritional adequacy, life-stage suitability, manufacturer information and your dog’s needs.WORKING DOG reference library · Added 2026-10-19 · Expert review pendingThis educational guide has not been reviewed by a veterinary professional. Discuss decisions about your dog’s health or diet with your veterinarian.Read beyond the front labelRecord the exact product and intended life stage. List what you still need to know rather than treating phrases such as premium, natural or high energy as a complete nutritional assessment.Ask the manufacturerWSAVA provides questions about the people formulating a diet and how it is evaluated. Save the answers alongside the product details so comparisons are based on the same questions.Make a veterinary shortlistDiscuss the shortlist in the context of your dog’s medical history, present ration and work. Keep any commercial relationship separate from the nutritional explanation.Compare the cost of the actual daily ration, storage needs and reliable availability once suitable options are identified. Record the exact formula because similarly named products may be intended for different life stages.Ask how to compare the products on an equivalent basis, including their energy information. Price per bag and prominent ingredients alone cannot tell you what the dog’s eventual daily ration will cost.Adequacy is different from ingredientsRSPCA’s feeding guidance recommends a balanced commercial diet appropriate to life stage and health status. An ingredient list does not, by itself, establish the finished diet’s nutritional adequacy or quality control. Record the product’s intended use and distinguish a complete diet from a complementary food, topper or treat. Ask for an explanation of how the claim is supported and which quality checks apply. If comparing home-prepared and commercial options, include formulation and preparation responsibilities in the comparison; a short list of familiar ingredients is not a nutritional assessment.Common questionsCan I choose a complete diet from its ingredient list alone?An ingredient list alone does not establish nutritional adequacy, formulation expertise or quality control. Check the intended life stage and the manufacturer’s supporting information.Sources & further readingReferences for this guide.
