Why Some Dogs Don’t Survive Parvovirus, Even in the Clinic
When a pet owner makes the decision to admit their dog to a veterinary clinic, it comes from a place of hope.
Many believe and expect that with IV fluids and medicines their dog will survive. While many parvo patients recover with aggressive treatment, unfortunately survival is never guaranteed.
Here are some reasons why a dog may not survive with parvovirus.
1. Intestinal Damage.
The virus destroys the intestinal lining, makes the dog unable to absorb nutrients, fluids, or medicines properly.
Even if we give IV fluids and antibiotics, the body may already be too weak to repair the damage.
2. Severe dehydration.
Dogs with parvo lose large amounts of fluid through continuous vomiting and diarrhea.
Sometimes the fluid loss happens faster than the body or even IV fluids can replace.
3. Weak Immune System
Parvo lowers the dog’s white blood cells, weakening its defenses. Bacteria that were once harmless can then grow out of control and lead to dangerous secondary infections.
4. Delay in Presentation.
A dog may appear active or with little vomitting but internally, parvo may already be causing organs to shut down.
By the time they arrive at the clinic, the virus has already overwhelmed the body systems.
5. Every dog responds differently
Age, breed, weight, hydration level, vaccine history, and even genetics affect survival.
Some puppies simply don’t have strong enough bodies to fight such an aggressive virus. Some also harbor a stronger strain of the virus.
6. Parvo is Unpredicatable.
Veterinarians give everything including fluids, antibiotics, anti-vomiting medications, electrolytes and constant monitoring.
But the virus can still progress faster than treatment can save the patient.
Parvovirus is one of the most severe infections we treat in dogs. It attacks the body in ways that even strong medications can't always reverse. The bottomline is, keeping your dog vaccinated with the 5-in-1 vaccine is one of the most effective ways to protect them. It prevents dangerous infections like parvo and distemper, and stops these diseases from spreading to other pets
