    One of the most popular methods of feeding dogs is giving them complete commercial feeds. When a decision is made to feed the dog with a dry food, selection of feed should not be made based on its price but in the first place on its quality. The research material consisted of 9 commercial maintenance feeds for adult dogs. The feeds tested were in granular form. Basic chemical composition in dry matter was determined for each feed (total protein, crude fiber, crude fat, crude ash and nitrogen-free extracts). Obtained results were compared with data provided by the manufacturers on labels of testes feeds. Metabolisable energy was calculated for each feed, based on the calculated chemical composition. All tested feeds satisfied minimal demand for total protein and crude fat. Three of them did not, however, meet minimum standard for adult dog feeds with respect to the level of metabolisable energy. Comparison of data on nutritional value provided by the manufacturers with results of own analyses showed that in several cases the manufacturers over- or underestimated content of particular nutrients. In 6 out of 9 feeds the manufacturers declared significantly higher content of protein. In one case the manufacturer declared significantly lower fat content that the one resulting from performed chemical analyses.
