Dog vomits yellow thick substance

When a dog vomits a yellow thick substance, consider five main issues:

Dietary problems: Observe the vomit of the dog. If it contains partially digested food residues, it is suspected that the dog is vomiting due to indigestion. There are many causes of indigestion, such as the dog eating cold or stomach-irritating foods, or possibly swallowing an foreign object. Observe the dog's vomit and its mental state.
Parasites: Dog owners should pay attention to the frequency of deworming for their pets, which includes both internal and external parasites. Vomiting can be caused by internal parasites. Observe the dog's vomit, especially its feces, to see if there are parasites. Sometimes, the dog may also bleed in the stool, which is a sign of parasites.
Vomiting caused by gastrointestinal diseases: When a dog suffers from acute or chronic gastroenteritis, it may vomit. The yellow thick substance indicates that the gastric mucosa is damaged. Other symptoms may also occur, such as lethargy, loss of appetite, and even complete loss of appetite, diarrhea, and bloody stools.
Internal organ problems: Vomiting caused by liver and kidney problems. This should be of great concern to dog owners. If the dog experiences severe vomiting, loss of appetite, poor mental state, abdominal pain, or even loss of consciousness, it should be taken to a veterinary hospital for a detailed examination as soon as possible.
Poisoning: Dogs may vomit after accidentally eating substances they cannot digest, such as onions, grapes, chocolate, and xylitol. Additionally, poisoning caused by toxic substances can occur. If this happens, the dog will not only vomit but also show symptoms of anemia. Dog owners can make a preliminary judgment by checking the color of the dog's gums.
