Parvo Symptoms

Canine parvovirus, also known as parvo is a highly contagious disease that affects a number of dogs and puppies. Spread through direct and indirect contact with other dogs, parvovirus in dogs can be life-threatening for your pet, especially for puppies between the time of weaning and six months of age. Moreover, the virus is able to survive on inanimate objects like clothing and cage floors for months. Insects and rodents may also serve as vectors of the virus. Although adult dogs can get the disease, it is the puppies which are not vaccinated or protected by maternal antibodies that are more prone to suffering from a severe form of the parvovirus. Before we look at the parvo symptoms in puppies and dogs, let us look at the pathophysiology of the disease.

Canine Parvovirus Types

There are two types of parvovirus in dogs, intestinal and cardiac form. Intestinal type of parvo which is a severe form of the disease, can affect dogs which come in contact with the infected soil and feces that carry the virus. The virus then replicates in the tissues of the throat and then moves into the dog's bloodstream. It depletes the lymphocytes in lymph nodes and results in the necrosis and destruction of the intestinal tissues. This may lead to symptoms such as bloody diarrhea and severe vomiting in dogs. The cardiac form of parvovirus in dogs also known as myocarditis affects the unborn puppies in the uterus. It results in the degeneration of the heart muscles of the puppies. It is fatal, death occurs in about seven to eight weeks of birth due to respiratory and cardiovascular failure.

Parvo Symptoms in Dogs

The appearance and the severity of the canine parvo symptoms and treatment depends on the dog that are affected by the disease. Usually in dogs less than six months of age, the severity of the symptoms is much more. Puppies younger than twelve weeks are prone to suffering from the severe form of the disease. It is also observed that certain dog breeds like Rottweilers and Doberman Pinscher puppies are twice as susceptible to this disease than the other breeds. Most of the symptoms are manifested within five to ten days of being infected by the virus. The most common parvo symptoms in dogs include dog health problems such as:

• Diarrhea
• High- or low-grade fever
• Vomiting
• Dehydration
• Secondary infections
• Loss of the electrolyte balance
• Anemia
• Depression
• Anemia and loss of protein
• Loss of appetite
• Lethargy

In the later stages of the infection, you will notice a distinctive foul odor and with the lowering of the white blood cells in the blood the dog starts weakening. As the disease progresses the puppy may have difficulty in breathing and may have difficulty breathing. This can result in the sudden death of the dog.

Parvo Treatment in Dogs

If your dog is displaying any of these symptoms, then it is best to see the veterinarian right away. This is because the constant diarrhea and vomiting can lead to dehydration and even death. Except for the relatively milder cases, hospitalization is needed to cure the parvo cases. The treatment will constitute maintaining the normal body composition by the appropriate intravenous fluid therapy and preventing secondary bacterial infection. Length of the treatment depends on the severity of the parvo disease, the age of the animal and the secondary infections that are caused due to the virus.

Anti nausea injections, antibiotic injections such as cefoxitin and administration of IV fluids is the best way of treating the parvo symptoms. As the dog starts retaining the fluids, the IV fluids can be stopped and some bland food can be introduced.

The best way to avoid the parvo symptoms in puppies is to make sure that they have received the appropriate vaccinations. Till then, do not expose the puppies to kennels, parks or other public areas where your dog may have a chance of contacting the parvovirus.
