An increasing number of owners are sharing details about their pooch's favourite dog food and so forth, with one in ten now having their own social networking profile.
Commenting on the research by PetPlan insurance, Sam Guiry, editor of Pet Gazette, said that the emergence of 'petworking' was inevitable.
She said: "As a nation of pet lovers, we seem quite keen to share stories about our animals and find out more about other people's pets.
"I think it was only a matter of time before social networking websites spread to the pet sector."
Ms Guiry also pointed out some social networks aimed specifically at pets. These include Dogster, MyDogSpace, MyCatSpace, UnitedDogs, UnitedCats and yourpetsdailylife.com, which is a family orientated website.
She added that in the future there will be many more social websites aimed at pets.
The research by PetPlan showed that half of owners share pictures of their four-legged friends online.
