This study aimed to compare the carbohydrate, fatty acids and digestion values of 29 commercial extruded dry-type dog foods produced for large breed adult dogs. In the study, total dietary fibre (TDF) values of dog foods differed significantly among commercial brands and ranged from 19.02 to 38.09% dry matter (DM) (P < 0.05). The average soluble dietary fibre (SDF) and insoluble dietary fibre (IDF) contents of dog foods were 6.27 and 20.09% DM, respectively. The average values of non-resistant starch and β-glucan in dog foods were 30.90 and 0.52% DM, respectively. The average linoleic acid, α-linolenic acid (ALA) and eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA) levels in dog foods were 2.21, 0.03 and 0.11% in DM, respectively. The total starch value was positively correlated with the gas production value (r = 0.516) of dog food (P < 0.05). As a result, it has been determined that the resistant starch and β-glucan levels differ in the dog food. EPA + DHA, linoleic and ALA acids were below international standard values in some dog food samples. Although in vitro digestibility of dog food was adversely affected by the increase in IDF and palmitic acid contents; in vitro digestibility contents in dog food were positively affected by the increase in soluble dietary fibre and stearic acids.
