Why does the puppy not gain weight after eating? The digestion and absorption function of the gastrointestinal tract of the puppy is not good, and there are parasites in the puppy's body that have not been driven out in time. The puppy's dietary nutrition is not comprehensive enough. When the puppy is four or five months old, it is in a transition period and will appear thinner. Viral infections or chronic diseases in puppies lead to intense physical exertion or excessive exercise.

1. Gastrointestinal absorption and digestion problems

The digestion and absorption function of the gastrointestinal tract is poor, resulting in less absorption of nutrients. Even if some parents feed their dogs enough food every day, have enough nutrition, and do deworming and other things, but they still don’t gain weight, then this situation is probably due to gastrointestinal absorption and digestion problems. If the gastrointestinal function is not good (the digestive enzymes that break down food are abnormal, nutrients cannot be absorbed, etc.), it will be useless no matter how much you eat.

2. Internal parasites

Dogs need to be dewormed regularly every 3 months. If they are not dewormed regularly, it is likely to be malnutrition caused by parasites. It is best to deworm the dog as soon as possible! If the dog has If there are parasites, nutrient absorption will be poor, which is also the reason why dogs cannot eat and gain weight.

3. Nutritional deficiencies

Make sure that your dog’s daily meal intake is normal. If it is not full, there will not be enough nutrition for the dog to gain weight, but do not overeat to avoid causing discomfort. If your dog eats commercial dog food, you should feed it according to the feeding amount; if it is homemade dog food, you should pay attention to a balanced nutritional mix and comprehensive nutritional supplements. Don’t just feed it meat, but add appropriate supplements. vegetable.

IV. Transition Period

When a dog is four or five months old, he will appear thinner and his hair will become sparse and shed. If this happens, it should be a transition period. Dogs at this time may become anorexic or even picky eaters, resulting in failure to gain weight. Don’t worry if there is a transitional period. Feed normally and prevent picky eating. It will be normal after a while.

5. Intense physical exertion

When viral infection or chronic disease leads to intense physical exertion; or after pregnancy and childbirth, when many puppies need to be nursed; when the amount of exercise is excessive. The metabolism in the body is more intense than usual and will consume more calories than usual. If sufficient nutrition is not provided, it will also be the reason why the dog does not gain weight.
