DEFRA are calling for responses to a consultation on banning third party sales of puppies. Click on the link to have your say.
If enacted, it could be possible that the commercial sale of puppies and possibly kittens and other animals would no longer be legal from pet shops. Currently, pet shops can apply to their local authority for a licence to sell puppies and are subject (in theory at least), to regular inspection.
However, even if pet shops are capable of providing suitable conditions from which to house and sell puppies which is extremely doubtful, they can only guarantee a regular supply of puppies from mass breeding. As the BBC TV documentary The Dog Factory proved, some of these outlets are a boon for puppy farmers, including those masquerading and even functioning as regular breeders.
This sounds like an excellent proposition, but the only way to prevent it from being just another statute amongst the 50+ laws that deal with dogs in the UK is for considerable resources to be put into enforcing and policing it. That seems highly unlikely in the current climate of severe local authority cuts.
