DNA shows that the Canine Parvo Virus (CPV) continues to mutate and evolve, so it’s important to stay informed and use the most current, effective vaccines against it. Some breeds, like Rottweilers, have immune systems that the Parvo virus attacks easily. Show dogs are especially susceptible because they are exposed to viruses brought from other parts of the world and country, through dogs that travel extensively on the show circuit.
Several dogs and puppies in New Engalnd died last year, and autopsies showed it was from Parvo, even though they were vaccinated against this. It was discovered that a new, mutated strain of Parvo had arrived in the US from Europe – type 2C (aka: strain 154). And the current vaccines only protected against the old strains.
Here is a synopsis of the new CPV type 2C:
– highly resistant to disinfectants, pH, and temperature
– confirmed in 14 states in USA, including NH
– highest numbers of CPV-2c detected in Oklahoma kennels
– many large dog breeding facilities involved
– physical properties of CPV are similar to other canine parvoviruses
– presents more severe clinical symptoms
– reported in dogs vaccinated for previous strain of CPV (type 2, A & B)
Type 2 Parvo has not been seen in years, yet most vets still use that vaccine when administering “combo” shots. Dog owners believe they are protected, but evidence shows that the new aggressive strain of CPV 2C attacks dogs previously vaccinated against the ‘old’ strain.
** research on the latest vaccines from Intervet and Galaxy show they completely protected dogs from CPV-2b and 2c Parvo viruses. These are separate vaccines – not part of a ‘combo.’ If your vet is not using these vaccines, your dogs are probably NOT protected.
Over vaccination is another subject and concern – research in the last ten years shows that “combo” shots should be discontinued. Only vaccinate for the three core diseases – parvo, distemper, and adenovirus. This depends on your area, and the amount of expected exposure to other viruses.
With all this research, why do vets still sell “combos” and still use outmoded vaccines? When I've asked, they say it’s because no asks for the most up-to-date protection, so they only offer what customers want.
Hmmmm … isn’t it up to the vets to educate their clients on that? They charge for vaccines that aren’t needed (and are now not recommended). Take charge of your dog's care and expect your vet to have done the latest research!
