The reasons why dogs only vomit but not have diarrhea:

1. Indigestion. If your dog eats dog food and still spits out dog food, it may be because he ate too quickly and there is air in his stomach, causing vomiting. It is recommended that owners fast for half a day to their dogs and then feed them digestion tablets to help reduce gastrointestinal pressure.

2. Gastrointestinal problems. If your dog’s vomit contains yellow water, foam, or blood streaks, it may be that the dog has been fed cold, irritating, or spoiled food, causing gastrointestinal problems.

3. Parasites. Parasites can also cause vomiting problems, along with loss of appetite and lethargy. If the dog has not been dewormed for a long time and prefers to play outside, parasites may appear in the body. Owners can feed their dogs some deworming medicine.

What to pay attention to when a dog vomits:

1. In the days after the dog vomits, dog owners should pay attention to the following diet for the dog: . Don't give it snacks during this period, only let it eat dog food. And follow the rule of eating small, frequent meals. In addition, you can also give some tablets to aid digestion.

2. Keep warm and do not blow the air conditioner on it. If your dog vomits, you must pay attention to keep it warm to prevent it from worsening. You can also add mats, blankets, etc. to your dog to provide certain warmth measures.

3. If you experience continuous vomiting within a short period of time, it is recommended to seek medical treatment. If you find that your dog still vomits continuously after eating, it may be due to urinary organ, pancreatitis, poisoning, internal organ problems or viral infection, and you need to go to the hospital immediately for examination and diagnosis.
