Dog owners in the Lancaster district have been advised to vaccinate their pets after cases of a deadly virus were reported in the area.
Parvovirus causes vomiting and diarrhoea in dogs, and can be fatal.
A Lancaster dog grooming company put out a warning on its Facebook page, saying there had been reports of cases in Lancaster and Morecambe.
VIP Dog Grooming told dog owners to ensure their vaccinations and immunity protection are up-to-date for their pets.
"If your dog is showing symptoms act fast," they said.
"Isolate your dog and seek immediate veterinary care.
"Do not allow your dog to mix with other dogs or attend any groom appointments/puppy/dog classes if showing any symptoms. We need to protect our canine community."
Other symptoms of parvovirus can be loss of appetite, listlessness, a depressed attitude and a dull, glassy-eyed stare.
Symptoms come on quickly, so many dog owners assume their pet has been poisoned.
The virus can be picked up on shoes and walked into a garden or yard, where it can live for years in the soil.
Puppies need a series of vaccinations to develop immunity while adult dogs need yearly vaccinations.
Local vets also confirmed cases of parvovirus across North Lancashire and South Cumbria in 2021.
