Dog owners are being urged to protect their pets against a potentially fatal disease after a sharp rise in suspected cases in the Aberdeen area.
In the last two months, vets at PDSA's PetAid hospital in Aberdeen have seen six dogs with severe vomiting and diarrhoea.
PDSA said the symptoms were a sign of canine parvovirus, a highly infectious disease which can lead to death.
The animal hospital saw only one such case during the whole of 2009.
Fiona Gregge, PDSA senior veterinary surgeon, said the sudden influx of cases was worrying.
"Parvovirus is often fatal and is particularly serious in puppies, as they also risk developing heart disease from the virus," she said.
"Owners should be aware that if their dog starts vomiting or develops diarrhoea it is crucial to contact their local veterinary practice as soon as possible."
The charity also urged owners to arrange vaccinations if their dogs were not fully protected.
