Pig owner can walk her pet pig like a dog, if she follows the rules

[Catherine]

A woman in Manchester has a pet pig. A nearby friend has his sibling. The pigs can be walked like dogs, but they must follow certain rules. They also need a permit, which they must carry.  She describes him as being like a very fat Labrador.
Everyone love seeing him and wants to take pictures with him.

Pet pigs are not that common and some places do not allow them. I guess having a permit to walk him is not that big a problem.
It proves that it is legal for her to have him as a pet.
