A dog prefers certain foods mainly for their fat content and texture, two factors that carry more weight than taste itself in food choices. These preferences often become fixed early on, during the puppy's first weeks of life.
Limited taste, decisive texture
Dogs have only about 1,700 taste buds, compared to nearly 9,000 in humans. Their sense of taste is therefore not very selective: they can distinguish sweet, salty, sour and bitter, but without the sensitivity needed to prefer one food based on taste alone. This is why texture (crunchy, soft, creamy) and fat content play a central role in what nutritionists call palatability: a food rich in fat stimulates appetite more effectively, because fats carry flavor compounds and create a pleasing sensation in the mouth.
Fats also act as a powerful energy signal for a dog's body—a carnivore that naturally values calorie-dense resources. A fatty food is therefore perceived as more satisfying, regardless of its actual flavor.

Food preferences shaped from the earliest age
Food experiences during the first weeks of life, through weaning and just after, have a lasting influence on an adult dog's preferences. A puppy exposed to a variety of textures and food types (wet, dry, chunked) typically develops greater dietary flexibility later on, while an early monotonous diet can create rigid preferences that are sometimes hard to change in adulthood. This early learning phenomenon, documented in several domesticated mammals, explains why two dogs of the same breed can react very differently when faced with a new food.
In practice, this means taste matters little, but the overall sensory experience—texture, fat content, early habits—gradually builds a dog's food preferences throughout life.
