All you need to know to protect your dog from Parvovirus

Parvo disease is the worst nightmare of every dog owner. Within days, a perfectly healthy puppy can pass from fun and energetic to a fatal disease. Therefore, all owners and breeders of new puppies must be aware of the dangers of parvovirus in dogs, how to prevent it, and what to do if the pup is infected with the parvovirus.

What is parvovirus in dogs and what is its risk?

  • Parvo is a highly contagious virus. It causes gastro-intestinal disease in puppies and small dogs, and without treatment it can be fatal
  • Merck Veterinary Manual classifies the virus as a disease of the stomach and small intestine, where the virus causes the most damage.
  • Serious viruses such as parvovirus weaken the puppy’s immune system and reduce the number of white blood cells, which reduces its ability to fight secondary bacterial infections.
  • The virus prefers to infect the small intestine, as it destroys cells, impairs absorption, and disrupts the intestine barrier.
  • Parvo disease also affects the bone marrow and lymph tissue, and in some cases, it can also affect the heart
  • Your veterinarian may place your puppy on an antibiotic treatment to combat these bacterial infections, and he will carefully monitor your puppy for additional complications.

What are the forms of Parvo disease in dogs?

Parvovirus in dogs is a highly contagious viral disease that affects dogs. The virus manifests itself in two different forms.

  1. Intestinal form: It is the most common, which is characterized by vomiting, diarrhea, weight loss and anorexia.
  2. Cardiac form: it is less common, and it attacks the heart muscles of fetuses and very small puppies, which often leads to sudden death of the dog

How long are puppies still contagious for Parvo disease?Parvovirus in dogs

  • An infected dog can begin spreading the infection of parvovirus in dogs to other dogs 4 to 5 days after exposure – often before the dog begins to show any clinical signs of infection.
  • The dog will continue to be infected with the virus for 10 days after recovery. This means that accurate diagnosis and quarantine are necessary for the health of the dog and other dogs as well
  • Parvovirus is a particularly flexible virus. It can survive indoors at room temperature for at least two months and is resistant to many commonly used detergents and disinfectants.

Who are more likely to develop parvo disease infection:Parvovirus in dogs

  • Small dogs between six weeks and six months
  • Non-immunized or fully immunized dogs are most at risk of developing parvovirus in dogs
  • Some dog breeds are more susceptible to infection with the Parvovirus, although scientists are not entirely sure why these dog breeds are at a higher risk than others and these chains are as:
  1. Shepherd Dogs
  2. Rottweilers
  3. Doberman Pinschers
  4. English Springer Spaniels
  5. American Staffordshire Terrier

Why do small puppies get parvovirus in dogs?

  • Puppies between six weeks and six months are at greater risk of infection with the virus that causes Parvo disease.
  • Puppies younger than six weeks old still retain some of their mother’s antibodies, assuming that the mother has received a full series of Parvo vaccines.
  • Puppies are vaccinated against Parvo at about 6, 8 and 12 weeks of age. They are more susceptible to disease until they receive all three doses in their vaccination series, which means owners need to take extra precautions during this time to prevent puppies from getting the virus.
  • Puppies should receive a dose of the Small Dog Virus vaccine between 14 and 16 weeks, regardless of the number of doses they received earlier, to develop adequate protection.
  • Shoes that have come into contact with infected stools can transmit the virus to the dog’s environment, which is worrisome as there is evidence that parvo can live in the soil for up to a year. If you suspect that you have ever contacted stool, you will need to wash the affected area with a home bleach (chlorine), one of the few antiseptics known to kill the virus.

  • Medicines that veterinarians may use to treat parvovirus infected dogs include antiemetic drugs, antacids, antigastritis, antibiotics and veterinary antiseptics to fight parasites. Treating ticks and fleas in dogs
  • Dogs have a survival rate of about 70% when treating in a veterinary hospital, but death may be caused by severe dehydration, severe secondary bacterial infection, bacterial toxins in the blood, or severe intestinal bleeding.

What is the Parvovirus in dog’s vaccination program?

The most important dog vaccination

  • Small pups are susceptible to infection, especially because the natural immunity provided in their mothers ‘milk may fade before the puppies’ immune systems become mature enough to fight the infection.
  • If a puppy is exposed to parvovirus during this protection gap, he may become ill.
  • An additional concern is that the immunity provided by breast milk may interfere with an effective response to vaccination. This means that even puppies may occasionally get infected with Parvovirus
  • To reduce protection gaps and provide the best protection against Parvo disease in the first few months of life, a series of puppy vaccines are given.
  • Puppies should receive a dose of the Small Dog Virus vaccine between 14 and 16 weeks, regardless of the number of doses they received earlier, to develop adequate protection.

Parvovirus vaccine is recommended for all small pups and is usually given in a series of three doses:

  1. When the puppy is between 6 to 8 weeks old,
  2. And again in 10 to 12 weeks,
  3. In 14 to 16 weeks.
    • A booster dose is given after one year and every 3 years thereafter.

Protection against parvo disease:

  • Unvaccinated puppies and fully immunized puppies should not be exposed to unvaccinated dogs or to environments in which unvaccinated dogs can enter the Parvovirus, such as dog parks
  • While it may be tempting to bring your new puppy with you everywhere you go, its health depends on keeping it safe until it is fully vaccinated against this life-threatening disease
  • Unvaccinated puppies can be safely bred with fully vaccinated adult dogs in safe environments such as your home.
  • Vaccination reduces the risk of spreading deadly diseases such as parvovirus in dogs, dog socialization and training are very important to proper development, but it is up to you to ensure that your puppy is socialized in a safe environment. A puppy should never be placed in situations such as daycare or training classes until they complete their vaccinations at the age of 14 to 16 weeks.

  • And if they do not continue to receive lifelong immunization doses as recommended by the veterinarian, their antibody levels can be significantly reduced and will be susceptible to infection with the Parvo disease.
  • Some pet breeders choose to test dog antibody levels every year before getting vaccinated. If antibody levels are low, vaccination is recommended
  • The viral mutation can also make puppies susceptible to other strains of parvovirus that are not included in the vaccine.
