In the process of raising puppies, vomiting will always occur for some reason. Many owners will feel nervous about this. Let me tell you about the puppies. What causes frequent vomiting?
1. Psychological reasons.
Why does a puppy often vomit? Part of this is due to psychology. It is very simple. If our puppy vomits soon after eating, and most of the vomited food is food, he then eats the cooked food again. This is a relatively common reason. It does not have much effect on the puppy's body, and there is no need for them to take medicine or see a doctor.
2. The food corridor is blocked.
Why do puppies often vomit? It may be because it ate some food that it was not allowed to eat, and then its food canal was blocked. If it eats more food later, it will cause vomiting due to the unsmooth food canal, and it will continue to happen. He stretched his neck, and most of what he spit out was saliva, not any food. Most of the items that can get stuck in a puppy's food channel are relatively hard materials, such as bones. If it is very shallow, we can remove the foreign body. If it is deeper, you need to see a doctor.
3. Gastric ulcer.
If the puppy vomits yellow-green objects, it means that it may have vomited some bile. At this time, there must be some problems with its intestines or stomach. In most cases, puppies have stomach problems. For ulcers, you need to take your puppy to the doctor immediately for treatment, otherwise it will cause a more serious disease.
4. Stomach bleeding.
If the object vomited by the puppy is the color of the coffee we usually drink, it is somewhat different from the color of the feed, and it is not very similar to the color of the food it eats. At this time we can start diagnosis and treatment. It may be stomach bleeding. Because the color of a puppy with gastritis is brown. At this time, we might as well give it some anti-inflammatory drugs first, and then the food it eats should be as light as possible, not too spicy, and some meat foods should not be eaten again, so that it can recover slowly.
The above are some explanations about the causes of vomiting in puppies. When facing different problems, you must take corresponding measures. I hope everyone will not panic when encountering similar problems.
