canine parvovirus emerged in 1978. it’s believed a virus similar to feline panleukopenia crossed over from cats to dogs. within two years, the virus had spread worldwide.
signs of illness, including lethargy, vomiting, diarrhea, and fever, appear within three to 10 days of infection.
most commonly, the canine parvovirus virus attacks the gastrointestinal system. it spreads into the bloodstream, attacking rapidly dividing cells in the lymph nodes, intestines and bone marrow.
there is also a less common cardiovascular form of the virus that attacks the heart muscles.
unvaccinated dogs are particularly at risk. so are young dogs due to their developing immune systems.

how does the virus spread?
canine parvovirus mainly spreads through contact with an infected dog or the feces of infected dogs, and it doesn’t take much. indirect contact is enough.
the virus is so dangerous because it’s extremely resilient. it can withstand most household cleaning products, along with cold, heat, and humidity.
it can also survive in various environments without a host for years. dogs can get infected from places such as kennels, grooming tools or simply walking on grass.
“it can easily jump from one dog to another, either through direct contact or by contaminated surfaces, food, and water,” according to the province.
