If the dog has a crown, the spirit is not very good, and he sleeps all the time, does not eat much, and will also vomit and have diarrhea. If the dog has a coronary for a long time, it will become thinner and thinner, and it will also pull bloody stools, and in severe cases may die.

Although a dog with a corona occurs throughout the year, it is most severe in winter common. Generally, the virus is transmitted between dogs through the respiratory tract, digestive tract, feces and pollutants. The infection is very fast and can spread within a few days, which is generally difficult to control.

So if pet owners find that their dogs have similar discomfort, they should take them to the hospital as soon as possible. Early medical intervention is the key to successful treatment.
