Do dogs experience taste as we do? What matters in the bowl

Dogs can sense sweet, sour, salty, bitter and umami. Nevertheless, they experience food differently than we do, because smell, temperature, texture and experience shape their preferences. A new 3D study even changes what we know about the number of their taste buds.

If your dog enthusiastically devours one piece of food and leaves the next one lying around, his decision seems very clear. But does he taste the same as you? Dogs have taste buds and can distinguish between several basic tastes. However, their entire feeding experience is very much influenced by smell.

For a long time it was often claimed that dogs only had around 1,700 taste buds. A 3D study of the dog's tongue published in 2026 came to a significantly higher estimate: around 7,649 taste buds. However, the tongues of five adult mixed-breed dogs were examined. The number is therefore an important new state of research, but not an exact value for each individual dog.

Dogs can sense sweet, sour, salty, bitter and umami. Umami describes a savoury, protein-rich taste. Bitter receptors have an important protective function because many potentially harmful substances taste bitter. However, you should never rely on your dog to automatically avoid poisonous things.

“Spicy” is not a distinct flavour. Capsaicin from chilli activates heat and pain receptors. Dogs can also feel this burning sensation. Spicy foods therefore do not belong in the bowl and can irritate the mouth and digestive tract.

What we experience as aroma arises from taste and smell. Dogs' sense of smell is particularly powerful. Therefore, a food with a more attractive aroma can seem more interesting, even though the basic composition is hardly different.

Temperature and humidity also play a role. Wet food that is at room temperature or slightly warmed smells more intensely than very cold food. This can help with picky or older dogs. However, only heat food slightly and evenly; hot spots can injure the mouth.

Texture also counts. Some dogs prefer soft food, others prefer crunchy pieces. Dental problems, nausea, pain, stress and medications can suddenly change preferences. A dog who unexpectedly refuses his usual food is not automatically “spoilt”.

Previous work on behavioural physiology describes special reactions to water in the front area of the tongue in dogs. The new 3D study found a particularly large number of taste buds at the tip of the tongue and in the back of the tongue. When drinking, the tip of the tongue first comes into contact with water, while at the back, food that has already been chopped up and mixed with saliva is analysed more closely.

Food preferences are not just caused by receptors. Early experiences, habits, previous feeding, positive or negative situations and health status influence what a dog likes to eat. If you immediately offer cheese or sausage after every moment of hesitation, you can also inadvertently teach your dog that waiting pays off.

This does not mean ignoring food refusal. Check first:

Seek veterinary advice early if your dog continues to refuse food, has other symptoms, or is a puppy, very small, old or ill.

Palatability and nutritional quality are not the same. A strongly flavoured food can be eaten with pleasure and still not have an optimal composition. Conversely, the best formulation is of no use if it is permanently refused or not tolerated.

Suitable food must take into account nutrient requirements, life stage, activity, body weight and health characteristics. Taste is part of acceptance - but not the only quality criterion.

Dogs have a more varied sense of taste than the old figure of 1,700 taste buds suggested. However, their feeding experience is not the same as ours. Smell, texture, temperature, experience and health are important factors. Sudden changes in eating are therefore important information and not just a whim.
