Canine parvovirus disease

definition

Parvovirus, which is caused by canine parvovirus (CVP 2), is an acute inflammation of the heart muscle (myocarditis) or inflammatory disease of the small intestine (enteritis). The little virus is very resilient. So it stays in rooms with room temperature for months, maybe even years.

Disease origin and development

The pathogen is absorbed through the mouth. It then multiplies in rapidly dividing cells. If the dog is less than three months old, this division takes place in the heart. In dogs over three months old, the localization is in the intestines. The damaged intestinal wall allows toxins and bacteria to enter the circulation, which can cause sepsis.

Clinical picture – symptoms

The inflammation of the heart muscle resulting in puppies under three to four months old runs off quickly and leads to death within a few hours or days. The symptoms are those of acute heart failure with pulmonary edema (penetration of blood fluid into the lung tissue): shortness of breath, rattling breathing noises, blue discoloration of the mucous membranes and fever. Older dogs develop a fever and severe liquid diarrhea that soon becomes bloody. Due to the loss of water, weight can be reduced by up to 15 percent.

forecast

The prognosis for myocarditis is very poor. The one with enteritis under therapy a little better (still many deaths). However, problems can still arise due to excessive dehydration.

prophylaxis

The best way to protect older dogs is to vaccinate them. In the case of puppies, the matter is more complicated in that they (if the mother was vaccinated) are initially protected by the maternal antibodies, but these quickly drop below the protective level. Usually in the fifth week of life. It does not make sense to vaccinate this early because the remaining maternal antibodies treat the weakened vaccine virus as an infection and inactivate it. However, they are not sufficient against a real infection, which is why one speaks of an “immunological gap”.
