Parvo in Dogs
Report of vaccinated dogs developing parvovirus - 11.1.21

What is parvo?

Canine parvovirus (parvo) is a virus (germ) that makes dogs sick. The virus attacks a dog's intestines and immune system. It is highly contagious between dogs and is often fatal to them. Every year, hundreds of dogs in Los Angeles (LA) County get sick and with canine parvo. You can protect your dog by getting them vaccinated. People do not get sick from canine parvovirus.

How does parvo spread between dogs?

Dogs can catch parvo when they touch other dogs that have it or the ground where a sick dog has walked or defecated. A dog with parvo contaminates its environment with the virus. So dogs can also catch parvo from the bedding, toys, bowls, and even the yard of a dog that has parvo. The virus can live for months in an environment, including in public parks and dog parks. Puppies are most likely to catch it. Humans do NOT get sick from this virus.

What are the signs of parvo in dogs?

Parvo causes vomiting and diarrhea in dogs. The diarrhea is usually severe and often bloody. Dog with parvo usually become very lethargic, dehydrated and have no appetite. Dogs can die from parvo.

How can I protect my dog from parvo?
Get your dog vaccinated! Vaccination save dogs’ lives and saves money. It costs much less money to protect your dog with vaccinations than to treat your dog for parvo. The DHLPP (or DHPP) vaccine protects your dog from parvo (It is one of the "Ps" in DHLPP). One shot is not enough! Keep your puppy away from public areas until it has finished the first series of shots. Allow your puppy to play only with a few healthy, vaccinated dogs in a yard where you know no sick dogs have been in the last year. Protect Your Dog from Parvo! (English & Spanish)

Reporting Cases of Parvo in Dogs in LA County
Parvo in dogs is reportable in LA County.  Parvo in dogs is not transmissible to humans (zoonotic). However, cases help indicate areas of LA County with reduced access to, or utilization of, veterinary services.  As a result, the risk for exposure to zoonotic diseases is likely higher in such areas. Data on parvo in dogs indicate areas in LA County where outreach services involving animal health and zoonotic diseases are needed most.
Cases of parvo in dogs are reported by animal shelters, veterinary hospitals, and occasionally by the public. Cases are counted as either confirmed or suspected according to LA County's Case Definition for Parvo in Dogs.
