Otsego County, Michigan - Alarm bells have sounded for dog owners in Michigan, as a new virus with symptoms similar to the canine parvovirus has killed at least 30 pups.

State and federal agencies are now investigating a mystery virus that's responsible for killing more than 30 dogs in reported cases in Michigan over the last two months.

The disease causes gastrointestinal problems and has been said to be claiming the lives of young dogs within three days, in many cases. Symptoms include bloody diarrhea and vomiting, and most of the deaths occurred in puppies and senior dogs.

The virus is thought to have originated in Louisiana, but is now spreading at lightning speed through a number of counties in Michigan.

"The state is in a panic right now," Clare County Animal Control Chairman Rudi Hicks said.

The virus is similar to parvovirus, yet local authorities said many of the sick dogs tested for parvo have had negative results. Yet there are traces of parvo showing up in some autopsies, which is spread through dog-to-dog contact and contaminated feces.

Experts believe the new disease could be a new strain or pathogen, and are unsure of exactly how it spreads.

In the meantime, dog owners are being strongly advised to keep up with routine vaccinations, clean up dogs' waste, and keep them away from areas with high dog traffic, like dog parks.

Michigan governor Gretchen Whitmer tweeted tips to keep dogs safe on Tuesday.

"If you don’t know if your dog is properly vaccinated or you don’t know what properly vaccinated is, contact a veterinarian," said Melissa FitzGerald, director of the Otsego County Animal Shelter in Gaylord, Michigan.

"The State vets office is hoping to learn more and come up with a defense."
