The dog vomited a yellow lump, which may be caused by various reasons. For example, gastrointestinal problems, dietary problems, infections, foreign objects in the abdominal cavity may all cause this phenomenon. If the dog vomits yellow sticky substances, the owner should observe the dog's condition in time, and combine the dog's recent diet and activity to understand the dog's condition as much as possible to better determine the cause. If the dog has symptoms such as vomiting, diarrhea, fatigue, loss of appetite, or the vomiting of yellow and viscous substances is smelly or mixed with other odors, it is recommended to take the dog to seek medical treatment and inform the veterinarian of the dog's symptoms and recent conditions.

1. Gastrointestinal problems.

Yellow viscous substances may be a mixture of dog's stomach acid or yellow-green bile, which is often caused by problems with gastrointestinal digestion, abnormal gastric acid secretion, disordered bile excretion or gastrointestinal dysfunction.

2. Dietary problems.

Dogs eat improperly and eat too much fat, perishable, difficult to digest or unclean foods, which can also cause vomit to appear yellow and sticky.

Again, the cause of infection. Certain viral or bacterial infections can also cause the dog's stomach or intestine and produce yellow viscous substances.

3. Foreign objects in the abdominal cavity.

After eating or swallowing foreign objects, dogs may cause gastrointestinal obstruction or perforation, causing serious symptoms. One of them is vomiting yellow viscous substances. This situation requires medical treatment in time.

When the dog vomits yellow sticky substances, the owner should immediately stop the dog from eating and keep the indoor air circulating so that the dog can breathe fresh air. At the same time, keep the dog drinking water and observe the dog's condition. If the situation is serious, please seek medical treatment in time. In order to prevent the dog from spitting out such yellow sticky substances again, the owner should also pay attention to arranging the dog's diet and activities reasonably and keep the environment clean and hygienic.
