    • 3. antiemetic drugs – control the vomiting and nausea – Centrun or Cerenia
    • 4. pain killers like Banamine not approved for dogs (approved for equine only) – Dr. Y has used for years - 1ml p/10lbs

    • 18-22 wks of age
    • because of the extended maternal immunity
  34. Both an ____________ form of CPV vaccine is available. According to many authorities vaccines should include a modified live attenuated CPV-2 strain, this because the
    • inactivated (killed) and a modified live
    • immunity develops more rapidly and has a longer duration in dogs following vaccination of modified live vaccines compared to the killed product
  35. Modified live vaccine is better for parvo because they have a
    higher titer and it has a tendency to overcome the maternal immunity and produce increased antibody levels
  36. Why Continue Vaccinations Longer for Parvo Vaccines Than Others?
    The immune system response of puppies following vaccination depends on the amount of maternal antibodies present, high levels of antibodies block the immune response from exposure or vaccination as the puppy ages the level of maternal antibodies decrease until the puppy becomes susceptible to canine parvo infection. Unfortunately levels of maternal antibodies which are too low to prevent infection with virulence, canine parvovirus may still be high enough to block the response to vaccinations.

  78. Explain the Diphasic Curve
    Incubation period at 102o F is where the animal breaths in the aerosol that lasts apx. 4-6 days. Then the temperature jumps to 105o F and the animal starts showing upper respiratory problems (runny nose, runny eyes, coughing, gagging). In about a week the temperature drops back down to 102o F dog appears to be back to normal eating, drinking again – BUT the virus has moved from the URI into the lymphatics and is spreading to the nervous system. Once it reaches the nervous system, the temperature goes back up apx. 103.5o F and the animal stops eating and drinking again. Animal starts developing injury to the brain matter and virus starts moving along the spinal cord which leads to chorea and “chewing gum fits” where animals has a seizures at interval time periods (apx 10 mins).
