Dogs are naturally carnivorous animals, but dogs also eat a wide range of foods. In the wild, they occasionally eat grass, fruits and other plants. However, dogs are still carnivores by nature. Domestic dogs obtain food differently from their ancestors, and their food choices have also changed, but their underlying eating habits are fixed.

Some dogs are not picky eaters, while others, especially those of giant and miniature breeds, are extremely picky eaters. Dogs prefer meat to grain, and they may prefer a certain type of meat, such as beef. They like a variety of flavors and are especially fond of sweet foods and salty, strong-flavored foods. The smell of food is also important as it affects their appetite.

Most dogs will be happy eating the same food every day. If their diet is balanced and nutritious, then this eating habit is reasonable. But many dogs still like to eat changes in food, even if they cannot adapt to the new food at first and may even develop diarrhea. So the new food you choose for your pet should be the same type of food it normally eats.

Most dogs eat one meal a day, but if the frequency of their feeding is changed, they will adapt quickly. In the wild, dogs may only get one meal for several days, and even then, most dogs prefer multiple meals a day. No matter how many times a day you feed, as long as the food intake meets energy needs and the food is balanced and nutritious, your dog will stay healthy.

For most dogs, if you offer them unrestricted food, they will overeat, but this will vary from dog to dog. The dog's habit of overeating may be related to its previous life in the wild - when they might not catch prey for days. So when they eat, they defend their food, even against animals that are more powerful than themselves. At home, you should train your dog from an early age to give up food he can't eat. Still, you should not let children near a dog that is eating or chewing on bones. Dogs will not tell themselves that they are full. If there is something to eat, they will eat it consistently, so owners must be careful.
