As families take to the road with their pets, a mysterious disease is sickening hundreds of dogs

Many families are hitting the road across the Northwest, crisscrossing the Cascades and traveling up and down I-5 in search of family, turkey and pumpkin pie.

And many will have fido there, wedged in the back amid the suitcases and the cooler holding the green bean casserole.

But Northwest veterinarians are suggesting leaving your dog at home this year: Don’t bring them to family gatherings with other dogs, and maybe don’t drop them at the kennel.

A mysterious disease has been making dogs sick across the Northwest and nation.

It starts like a mild case of kennel cough, then develops into pneumonia-like symptoms. Some animals have died. And scientific labs aren’t sure what they’re dealing with yet – bacteria? A virus? Something else?

“The scary part I think is just not knowing what this disease is really,” Minden Buswell, a veterinary epidemiologist with the Washington State Department of Agriculture. “It’s not responsive to antibiotics right now, the kind of antibiotics that we’re using. We need to know what this disease is, and how best to treat it – knowing that our current treatments aren’t working.”

Buswell said it’s best to keep your dogs away from congregation areas, like communal dog bowls and dog parks and kennels.

“I was talking to some boarding facilities and recommending that they really up their biosecurity,” she said.

She recommended more cleaning, all dogs having up-to-date vaccines and minimizing the time that dogs interact with each other.

“If you can avoid congregations of animals, that would be the best at this time,” Buswell said.

Pandemic for dogs

A bit of a drive south, Kurt Williams is the director of Oregon Veterinary Diagnostic Laboratory at the Carlson College of Veterinary Medicine at Oregon State University.

“I think what’s interesting to me – not that we need it coming out of COVID – but the reminder that the diseases are dynamic,” Williams said. “And it’s a reminder of why the Oregon Veterinary Diagnostic Laboratory is here. And that is to address the known and unknown diseases that can crop up at any time.”

Williams said this shouldn’t be underestimated, it is a sort of a COVID-like-pandemic for dogs – a devastating disease.

The total number of dogs that have been affected is largely unknown, but hundreds of suspected cases are cropping up in Oregon, especially in the Portland area and Willamette Valley. There are more suspected cases across the country, but currently, none reported in Washington.

Oregon’s Department of Agriculture says it was aware of other cases including in New Hampshire and nearby northeastern states, Colorado, Indiana, Illinois, California and the Northwest.

The cases reported to ODA appear to primarily fall within three general categories, the agency says:

Chronic mild-moderate inflammation of the trachea and lungs with a prolonged duration (six to eight weeks or longer) that is minimally or not responsive to antibiotics; Chronic pneumonia that is minimally or not responsive to antibiotics; and Acute pneumonia that rapidly becomes severe and often leads to poor outcomes in as little as 24 to 36 hours.

ODA officials say they are working with reporting veterinarians and specialists at OSU’s Carlson College of Veterinary Medicine, the Oregon Veterinary Diagnostic Laboratory and the USDA’s National Veterinary Services Laboratory to find out what’s causing these cases.

Vulnerable to misinformation

Williams, at OSU’s lab, said he’s worried about people getting misinformation on this disease, since sick dogs are an emotional topic. He said he’s been contacted already by many people who have misinformation about the subject.

“Because of the emotional ties we have to dogs, people (can) become emotionally paralyzed in this process,” he said. “I hope they’ll pursue answers to this disease by relying on reputable journalistic sources and scientific experts that are speaking to those experts.”

Williams encourages people who are having trouble with their pet’s health to call the vet. But, he said in the unfortunate case that someone’s dog dies of the disease – Williams hopes the owner may consider donating the body to science.

“I do think it’s going to be very important to study animals that died of this entity to link what we see, happening in the tissues of the animals that we think we might have this disease,” he said, “Linking that back to how the animal became sick and how that animal became sick clinically — and we don’t have that yet.”

Both Williams and Buswell stressed that so far no known cases have transferred to humans. [Copyright 2023 Northwest News Network]
