Treasure Valley veterinarians say there's been a notable surge in recent weeks in the number of dogs suffering from parvovirus, which can be deadly in puppies that haven't received the full series of three to four vaccinations.
The WestVet Animal Emergency and Specialty Center in Garden City received a half dozen dogs over the Oct. 3-4 weekend. Two died.
"They were coming from all over the Valley," said Danette Drake, marketing and public relations director at WestVet.
Veterinary hospitals and clinics in Nampa and Caldwell each reported treating about 30 dogs in the past month.
"We typically see three to four a month, so that's 10 times as much as we usually see," said Dr. Fiona Caldwell at Idaho Veterinary Hospital in Nampa.
Blayney Veterinary Clinic in Caldwell has treated at least 30 dogs for parvo in the past month, said Dr. Kayla Williams. Five to 10 cases a month is typical.
The cause of the surge is a mystery to area veterinarians, but they suspect that a lack of public understanding about vaccination and hard economic times may be factors.
Parvovirus is a highly contagious virus that is transmitted through feces. The virus attacks the intestines or, less commonly, the heart. The virus primarily affects puppies, though adult dogs that were never vaccinated may become ill.
Infected dogs typically suffer severe dehydration from vomiting and diarrhea. They typically need intravenous fluid transfusions.
The survival rate is about 70 to 80 percent for those that receive medical care, vets said.
"We can't save every one of them. It's a serious illness ... but some of the puppies will get better in 24 hours," said Melissa Parks, practice manager at River City Veterinary Hospital in Meridian.
The pain, expense and heartache caused by parvovirus is largely preventable, experts say.
The cost of vaccination varies from clinic to clinic because it's administered as part of an exam - fees quoted by veterinarians Monday ranged from $35 to $70 per visit.
Dr. Amber Upchurch at Orchard Animal Clinic in Boise said the owners of a 7-month-old puppy spent about $3,000 to save the hunting dog earlier this month.
"He was a particularly bad case," Upchurch said. "He had three plasma transfusions."
Some puppy owners falsely believe that one parvo vaccine shot is enough, while others skip the vaccination to save money.
Veterinarians say puppies need a series of up to four parvo vaccine shots, starting at 6 weeks old. The shots must be administered every three to four weeks to build up the animal's antibodies.
A booster is advised at 1 year old and adult dogs should get one every three years.
"The vaccine for parvovirus is very, very effective, 99.9 percent effective. It's unfortunate to see so many cases because it does not have to happen," Williams said.
