At present, dehydration can only be prevented through infusion, because the dog cannot be fed water at this time. Drinking water may irritate the gastrointestinal tract, cause more severe vomiting, and aggravate the dog's condition. Parvovirus in dogs is a serious infectious disease that causes great damage to the body and has a very high mortality rate.

It is recommended that the owner take the dog to the hospital for treatment in time, replenish the water and energy needed by the body through infusion, ensure the electrolyte balance in the body, and cooperate with antiviral drugs, antibiotics and other drug treatments.

A dog with parvovirus has no appetite, will not eat or drink water, and only rehydration can prevent it from becoming dehydrated. If it doesn't vomit, you can force-feed it appropriately. If it vomits, you must stop food and water and replenish fluids.
