Cobar's local veterinary surgery is warning local dog owners of a current outbreak of the lethal parvovirus in town.

Canine parvovirus is an often fatal viral disease that affects unvaccinated dogs and puppies.

It is highly contagious and can stay on surfaces and in environments for a long time, withstanding cold, humidity, and heat.

Dogs can become infected by coming into contact with infected surfaces, environments, faeces, or other dogs.

"We have seen two cases here at the surgery, and we have had several reports of parvo by pet owners that have to come see us, after the animal has been deceased", a spokesperson for the Kidman Way Veterinary Surgery told the Western Plains App.

The RSPCA of NSW advises that the typical incubation period is four to six days and that symptoms include but are not limited to: lethargy, diarrhoea, loss of appetite, and vomiting.

Parvovirus progresses rapidly, with most deaths occurring within the first 48 to 72 hours of the onset of symptoms.

Parvovirus can be prevented by getting your dogs and puppies vaccinated, with an initial vaccination required and then several boosters needed in subsequent weeks.

Your dog is not fully vaccinated until this first full course is complete and it is advised to limit your dog or puppy's interactions until they have achieved full immunity.
