For people who keep Pugs, one of the scariest words is parvovirus. Once infected, a Pug often becomes very listless, loses its appetite, and develops severe vomiting and diarrhea. If these symptoms appear, owners may first use a parvovirus test strip to check, but once parvovirus is suspected or confirmed, the dog should be taken to a pet hospital immediately.
A Pug is a life, and once you choose to raise it, you should not give up on treatment easily. The original article also describes several home remedies that some owners try when dealing with parvovirus, though these do not replace veterinary care.

Herbal soup plus anti-inflammatory medicine
One suggested home approach is first to stop all food, since eating only increases the burden on the stomach and intestines. Some owners use a traditional herbal soup together with antibiotics and glucose support to try to control viral effects and prevent dehydration. If the dog begins to improve, treatment is then continued until recovery is stronger.

Gentamicin plus probiotics and norfloxacin
Another home-support idea is again to stop food, while giving antibiotics, probiotic-style digestive support, and glucose water. Because the dog is not eating, hydration and energy support become especially important. Even if the Pug begins to improve, treatment should not be stopped too early, because the condition needs consolidation.

Omeprazole plus soothing digestive support
A third approach described by some owners involves stomach-protective medicine together with anti-inflammatory support. The dog is kept off solid food and given plenty of water. Once improvement appears, small amounts of digestive support and thick rice soup mixed with a little egg yolk may be offered very carefully. Only the soup should be given, with no actual rice grains, and only in very small amounts.
Home care of this sort is complicated and requires patience. In the author's view, the most important thing is not just medicine but also encouragement and affection. A Pug in a very weak state still benefits from the owner's calm presence and support.
Even so, the most important medical principle remains unchanged: parvovirus is highly dangerous, and owners should make rapid veterinary treatment the first priority whenever possible.
