Vets issue urgent warning over spike in virus that kills up to 90 PERCENT of dogs – with rates rising in New York, Washington DC and Missouri

Pet owners have been urged to look out for a virus that is spiking in some parts of the US and is lethal in dogs. 

Parvovirus, often referred to as parvo — a highly-contagious disease that kills up to 90 percent of pooches — is above average levels in at least three parts of the country, New York state, DC and Missouri.

The most common symptoms are vomiting, diarrhea and loss of appetite. The virus is not tracked, so the total number of dogs to have died is not known.
