Canine parvovirus infection is a highly infectious disease among dogs. It occurs mostly in puppies between the ages of newborn to six months. It has been shown that Dobermans, Rottweilers, and Black Labradors are the most susceptible breeds, but any breed can be severely affected.

The signs that are seen with the parvovirus are depression, loss of appetite ( anorexia ), vomiting, and severe diarrhea. The feces will usually appear light gray, yellowish gray, or dark red. Indicating that there is blood in the stool. These signs may become worse due to stress, living in unsanitary conditions, or having other diseases occurring at the same time as parvo. As the disease progresses, the dog will become dehydrated due to extreme loss of fluid from the vomiting and diarrhea.

The cause of the infection is a virus that attacks the intestinal tract, white blood cells, and possibly the heart muscle. The virus is spread by dog-to-dog contact and coming into contact with feces from an infected dog.

The best prevention method against the parvovirus is vaccination. Another method is proper cleaning and disinfecting all kennels where dogs are housed. The virus can survive up to one year in the environment. The best disinfectant to use is bleach, which is simply mixed with one gallon of water to dilute the bleach out so it is not as strong. There is not a true treatment for parvovirus. The main concern for the animal is giving it sufficient amounts of fluid and electrolytes. The vomiting and diarrhea may not be stopped in all situations. Antibiotics will be given to help prevent against any secondary infections. The dog will be kept isolated during treatment and should remain there even after recovery for at least three days.
