CareVet of Middletown is urging local dog owners to keep an eye on their animals due to an increase in reports of parvovirus.

The clinic has seen a “huge uptick” in cases, said Medical Director Dr. Jessica Delgado. It generally sees 1-2 cases of parvovirus per year, but in one day in October, there were four cases before lunch.

“I used to work out in rural southeast Ohio, where parvo tended to be bad ... and I never saw this many cases a day,” Delgado said.

Parvovirus is spread through feces and stays in the environment for eight months to years even if the feces is removed, according to Delgado. Unvaccinated dogs also shed the virus into the environment.

“It’s a very hardy virus,” Delgado said.

The clinic, which is on Manchester Road in Franklin, is also seeing an increase in feline panleukopenia, which is from the parvovirus family.

The increase in feline cases started in August, which then slowed down. Canine cases increased in October.

Delgado said her team is seeing cases in mainly older dogs and even dogs who are vaccinated.

“Historically, if a dog has been vaccinated for parvo, we don’t see them clinically ill,” she said. “They may have come across it, but we don’t see them with the typical symptoms.”

Symptoms to look out for:

  • Severe or persistent vomiting
  • Bloody diarrhea
  • Extreme lethargy or weakness
  • Sudden loss of appetite

Cats coming in are typically ones that go in and out of the house or have another pet in the house that does, according to Delgado.

Delgado said she asked Greater Cincinnati and Northern Kentucky clinics if there has been a similar uptick, but those clinics have not reported significant increases.

Because of this, Delgado said it seems like the increase is localized to the Middletown and Franklin area.

To help reduce the spread of the illness and improve recovery outcomes, CareVet is advocating for early intervention, according to a press release.

The clinic also recommends pet owners exercise extra caution in dog parks, boarding facilities and grooming salons until more information is known about local cases.
