Parvovirus

Parvovirus is a viral disease in dogs It is an extremely dangerous virus to puppies and unvaccinated dogs.  This is because the virus is hard to kill, can live for a long time in the environment, and sheds in large quantities by infected dogs. The virus spreads through the shedding of cells, and it is highly infectious.  The growth of this virus takes place in rapidly dividing cells, such as those in the intestinal lining, bone marrow, and heart. The virus attacks and kills these cells, causing a myriad of symptoms and suppression of white blood cells.

This disease is very serious and there is a low survival rate.  Usually, adult dogs will not contract this virus unless they never received their puppy vaccinations, have not received a booster vaccination as an adult, or have a significantly lowered immune system. Parvovirus can live outdoors for months, if not years, and is resistant to many disinfectants.  However, it is susceptible to diluted bleach and some specialized cleaners commonly used in veterinary hospitals.  

This is a very serious disease. Some puppies infected with parvovirus will die despite prompt and adequate treatment. On average, 40% -75 % of puppies treated for parvovirus will live depending on how quickly they get treatment. Without treatment, 90% or more of infected puppies will die. If you have a puppy, do not take any chances. Have your puppy examined by your vet if diarrhea is a factor in any disease. It is better to be safe than to be sorry.

If your dog becomes infected with parvovirus and makes it through the first three to four days, there is a higher chance that the puppy will recover. It is vital, however, that a puppy receives supportive therapy immediately if Parvo symptoms arise. It must be stressed that this is not a bad case of doggy flu; without medical treatment, most puppies will die.

The parvovirus vaccine is imperative for puppies. When your dog becomes an adult, a booster is necessary. Puppies should receive a total of three vaccinations for parvo.  One vaccine at 8 weeks, one at 12 weeks, and one at 16 weeks of age. Seven to ten days after the last booster, your pup should have significant antibodies and can go anywhere you want to take them. When your dog turns one year of age, it should receive another booster.  After that point, your dog needs a booster vaccine every year or a titer to ensure that it still has the necessary antibodies.  

Since Parvo attacks the lining of the digestive system, it causes dogs and puppies to not be able to absorb nutrients or liquids. Puppies are especially prone to it because they have immature immune systems. When dogs and puppies contract Parvo, they often have a high fever, significant diarrhea (often bloody), vomiting, anorexia, and lethargy. Often within 24 – 48 hours of the first presentation of symptoms, they stop eating and drinking.  Additionally, they will have a bloody, foul-smelling, liquid-like stool. In some cases, dehydration, shock, and death can follow. 

Generally, it takes 7-10 days from the time of exposure for dogs and puppies to start showing symptoms and to test positive for Parvo. Parvo is highly contagious to unprotected dogs. Parvo spreads through a dog’s exposure to contaminated feces. However, being able to see the contaminated feces is not a necessity for the virus to be present.

The Parvo virus can live in the ground, on the ground, on any surface, on peoples’ hands, or on the clothing of people that have been around a contaminated animal or location. Dogs could also carry it on their fur or paws if they have laid, rolled, or stepped in contaminated fecal material. Parvo can live for many months outside of the animal. Adult dogs may be infected carriers without showing any clinical signs. Dogs with the typical diarrhea that parvovirus causes shed the virus even if they are not showing any other symptoms. 

Follow these recommendations to help prevent the spread of this disease. Keep the infected dog isolated from all other dogs for one month after full recovery. 

• Clean up all the dog’s stools in your yard.

• Use a 1:30 ratio (4 oz. in 1 gallon of water) of chlorine bleach and water to clean the area(s) where the puppy has been, food and water bowls, and if possible, the yard (it is better to kill the grass then infect another dog.

• Wash any bedding the dog has been in contact in the same bleach solution and hot water. You should also try to disinfect any other areas that the dog has been, like linoleum, kennels, crates, etc.

• Purchase Parvosol to spray on anything that cannot go into the washing machine.  For example, spray it on carpets, couches, and any other material surface. To ensure virus eradication, complete the Parvosol disinfection protocol twice.

• If you have any other dogs that are two years old or younger, or adult dogs that have never received the vaccination for Parvo, get them booster shots as soon as possible. Any other dogs in the house can have blood drawn for a titer to find out individual parvo resistance.

• Do not bring another puppy home for at least a year and run another full sterilization before you do so. 

• Do not bring any dogs into your home unless they are fully vaccinated.
