A pet shop with branches in Sutton and Kingston could be made an example of in Parliament, as MPs attempt to change the law on controversial puppy farms.

Petsville, on Sutton High Street, has been the subject of a deluge of complaints to Kingston and Sutton Council, prompting Kingston council leader Councillor Derek Osbourne to contact the Associate Parliamentary Group for Animal Welfare (APGAW).

APGAW, a cross-party group of MPs, will talk to councils, vets and other experts and consider ways to tighten laws on selling animals. One possibility is the introduction of puppy health testing.

The findings are likely to be published in September and the group will place pressure on the Department of Environment and Rural Affairs (Defra) to take their recommendations further.

Group co-ordinator Marisa Heath said: “There must be ways of ensuring the breeders have proved they have done checks for diseases, so pet shops can’t sell them without having that proof.”

Petsville has never broken any licensing laws while selling puppies but has been accused of importing puppies – which have later gone on to develop health problems – from farms in Ireland.

The Kingston shop featured on an episode of BBC’s TV show Rogue Traders, and a Facebook group calling for it to be shut down has since attracted 2,000 members.

Petsville, which has never had any action taken against it by the RSPCA, refused to comment.
