How to care for a dog with an internal medicine condition? Explaining with gastritis as an example

The usual signs are not eating, vomiting, and diarrhea, leading to severe dehydration and reduced resistance.

Intravenous fluids generally work best. Next, giving stomach-strengthening and appetite-stimulating drugs is fine, but giving only these drugs is not enough. Owners should administer medication according to the veterinarian's advice and prescription, but because the education level and clinical experience of veterinarians vary across different animal hospitals and clinics, you should find an experienced veterinarian to prescribe.

Generally, households should always keep drugs such as berberine and furazolidone on hand, but these drugs are not very effective against canine gastroenteritis. When the owner takes a sick dog to an animal hospital for treatment, they should pay attention to the speed of the intravenous infusion, whether there is any allergic reaction (mainly the immediate appearance of patches of red rash on the body after administration, especially on the lower abdomen, swollen eyelids, and a weak but fast heartbeat), whether there is vomiting, when the fluid will finish, what other drugs are being given, how to administer them, how many times per day medication is given, and whether there are any incompatibilities between drugs, etc.

After intravenous infusion, the nutrition a dog needs for a day has already been supplied, so there is no need to feed it again after returning home, but sufficient water should be provided. Drugs such as gentamicin, metoclopramide, Weidikang (commonly known as "stinky medicine"), lactasin, multienzyme tablets, yeast tablets, compound vitamin B, Zengshile, and penicillin should be drugs that owners keep on hand.
