Young (6 week to 6 month old), unvaccinated or incompletely vaccinated dogs are most susceptible. Breeds described as at increased risk include:
-Rottweilers
-Doberman Pinschers
-American Pit Bull Terriers
-English Springer Spaniels
-German Shepherds
Assuming sufficient colostrum ingestion, puppies born to a dam with CPV antibodies are protected from infection for the first few weeks of life; however, susceptibility to infection increases as maternally acquired antibody wanes.
- Stress (eg, from weaning, overcrowding, malnutrition, etc),
- concurrent intestinal parasitism,
-enteric pathogen infection (eg, Clostridium spp, Campylobacter spp, Salmonella spp, Giardia spp, coronavirus) have been associated with more severe clinical illness.
-CPV can remain viable in the environment for an extended period. In a kennel, shelter, or hospital situation, cages and equipment should be cleaned, disinfected, and dried twice before reuse.
-To limit environmental contamination and spread to other susceptible animals, dogs with confirmed or suspected CPV enteritis must be handled with strict isolation procedures (eg, isolation housing, gowning and gloving of personnel, frequent and thorough cleaning, footbaths, etc).
-All surfaces should be cleaned of gross organic matter and then disinfected with a solution of dilute bleach (1:30) or a peroxygen, potassium peroxymonosulfate, or accelerated hydrogen peroxide disinfectant. The same solutions may be used as footbaths to disinfect footwear.
-With appropriate supportive care, 70%β90% of dogs with CPV enteritis will survive. Dogs that recover develop longterm, possibly lifelong immunity.
