Dogs have a much shorter life span than humans, but they also have a full life cycle. The puppy stage is from 0 to 6 months old, the juvenile stage is from 6 to 1 years old, the mature stage is from 1 to 2 years old, the adult stage is from 2 to 7 years old, and the old age is from 7 years old. Like humans, dogs change their physical characteristics and organ functions during different stages of life, and their nutritional needs also vary. In other words, according to the age of the dog, we should promptly and reasonably adjust the diet and care to meet the needs of the body.

When the puppies grow up to 2 to 3 months, the calories and protein they need increase. The puppies can choose the dog food on the market according to their age. The proportion of dog food gradually increases, and the proportion of dog food is gradually increased. Soak in warm boiling water until soft. Feed dry dog ​​food to reduce the burden on the digestive system and eat small and frequent meals. If your dog has indigestion or weak bowel movements after eating, stay in touch with your family vet. In addition, regular physical examinations and vaccinations are also necessary, and should be carried out on time according to the doctor's instructions.

At this time, the dog's intelligence increases rapidly. At 3 months old, dogs can start some simple training. Developing habits such as defecation and sitting can be learned quickly.

Another thing to note is that puppies are not fully vaccinated and are susceptible to infectious diseases. Their bones and feet are immature, so try not to go out or engage in strenuous exercise.

At this time, the dog's body and intelligence will grow rapidly, and the demand for protein, calories and other nutrients will also increase. Choose dry dog ​​food based on the size of your dog. Large dogs require more protein and fat as they grow. Dry dog ​​food on the market is specially designed for small dogs, medium dogs, large dogs and other dogs of different sizes. Since the dog's digestive system matures gradually, puppies can eat twice a day. Medium-sized dogs can get some snacks in between meals. Large dogs require more nutrients, so they can maintain three meals a day.

Puppies require less exercise and can walk easily. Medium or large dogs need lots of exercise, and they can be taken for walks in parks or suburbs, or played with dogs that throw balls or pick up Frisbees. Large dogs tend to develop later and have longer bone and muscle growth cycles. Avoid exposing large dogs to excessive physical activity, such as long-distance running or mountain climbing, to avoid damage to developing bones and joints. This is also the best time to train your dog if you want your dog to learn a lot of moves or disciplines.
