It is important to keep the pet hydrated throughout the episode, and this means giving plenty of water to assist in rehydration. The pet should not go back to the solid foods quickly, but if you notice the condition has improved, you can boil some chicken for it in three days time. If the situation was caused by eating quickly, the solution might be in controlling the rations and making sure they are regular so that the pet is not so hungry that it ends up eating quickly. For the more serious cases, only a medical examination can help. As soon as you are troubled, you need to see a dog behaviourist. He or she will conduct the physical examination like feeling the pet’s stomach. If the situation is worse, scans will be conducted. But before all these, it is important for you to find the cause. For instance, my dog is vomiting because it has swallowed a toy, it has intestinal irritation, it has worms or worse, it has stomach cancer.
