My pet vomits after eating

When your dog or cat vomits, he or she is ejecting food from the mouth that has been in the stomach. This can be a natural defence that protects your pet when they have eaten something they shouldn’t have, or it can be a sign of illness. Vomiting can be acute, meaning short-lived and over within hours, or it can be severe and last for days. With some pets, vomiting is chronic and lasts for months.

Is vomiting normal?

Pets tend to vomit poisons quickly, but it may take several hours before vomiting occurs if the problem is an obstruction that prevents food from moving further down the intestinal tract.
To most, occasional vomiting is considered to be quite a normal thing for a dog to do. However, there are many causes of vomiting that are related to true disease or illness. Dr Roslyn of Greencross Vets believes the more frequent a pet vomits, the more likely there’s a problem.
“When dogs eat something that doesn’t suit their bodies, they can sometimes reject it, and behave quite normally afterward” says Dr Roslyn. On the other hand, certain common household products, like snail baits, cleaning solutions etc. can cause vomiting and may be fatal if left untreated. Therefore, it is always best to contact your local vet and be guided by their recommendations. 

What causes pets to vomit?

Dog and cat vomiting can be caused by problems from within the stomach and intestines (called the gastrointestinal or GI tract) and by problems from outside the GI tract, such as kidney disease. Common causes of vomiting are food allergies, illness, cancer, infections, drugs, parasites, plants, and poisons. Vomiting is also caused by incidents of overeating, foreign bodies, bloat (GDV or gastric dilatation volvulus), and constipation.
However it can be simpler than that. “Some owners have different ideas of how much is an okay amount to feed their pet,” says Dr Roslyn. “Sometimes vomiting can just be a matter of feeding them too much at once or your pet may also naturally have a sensitive stomach and a vet may prescribe a particular prescription diet or high quality premium food.”

What should I do if my pet is vomiting?

If you are concerned about the frequency or nature of your pet’s vomiting, contact your local Greencross Vet for treatment. The vet will investigate your pet to identify what might be causing the vomiting. From there the vet will monitor the pet and work together with the owner to determine the treatment plan.
