Dogs generally will not die from ascariasis, unless the dog has a more severe form of ascariasis. Common symptoms include loss of appetite, vomiting, heterophilia, indigestion, dysentery and constipation, and occasionally epileptic seizures. , this situation may lead to the death of the dog.

The dangers of roundworms in dogs:

1. Generally, the impact is small. When there are not many roundworms in the intestines, they only feed on the nutrients digested by the intestines. In most cases, they will not have much impact on the physical condition.

2. Malnutrition. When the number of roundworms increases, most of the nutrients in the intestines are swallowed up by the roundworms, and the dog will become malnourished. Typical symptoms are body weight and dry coat. When the roundworm population continues to increase, irritation to the intestines can lead to diarrhea. When the roundworms are large, they can block the intestines, cause intussusception, and cause abdominal pain.

3. Affect organs. In rare cases, roundworms burrow in the body and affect other organs, causing greater harm.

4. Death. When the number of roundworms in the body is extremely large, it can even cause death of the dog.

5. It is more harmful to puppies. Compared with adult dogs, roundworms cause greater harm to puppies. During pregnancy, roundworm larvae will migrate to the fetus with the blood circulation and grow inside the fetus. Three weeks after the puppy is born, they will appear in the puppy's body. Adult worms develop in the intestines.
