Paula Boydon, the veterinary director of the Dogs Trust, says that the spike in the number of illegal puppies coming into the UK is an indirect result of a change in legislation. Before 2012, you couldn’t bring a dog that was any younger than six months old into the UK; they had to have had their rabies jab at 12 weeks old, and the blood tests to prove it. It meant that smugglers didn’t bother to try and bring dogs in: Customers aren’t interested in buying older dogs, as they are harder to train and not as cute.
