Contrary to common consent, there is no published evidence that the addition of palatability enhancers to industrially produced foods increases the risk of obesity development in dogs. However, there is such evidence for added fat, which is both a conditional palatant and a concentrated energy source.
Ingredient mixtures of industrially produced, complete canine foods can vary markedly, but still be equally good. Feeding of dogs should aim at supplying adequate amounts of nutrients in an available, palatable and safe form that supports a healthy and long life.
Dog food marketing is dominated by trends. Differentiation, humanization and individualization are product trends initiated by the petfood industry. Dog owners’ attitudes have inspired the natural trend.
