Our dog trainer saved a spotless pedigree piglet from slaughter. It had no value to its breeder without spots. It now lives with her and her dogs and walks to heel and plays football with them and the Welsh cob foal who also walks to heel. Recently she got it a little piggy playmate. These two are definitely not for eating.
Pigs are intelligent and, as with any pet or farm animal, deserve a good home and proper care and feed and there are now stricter rules for their care so I second the advice to get some training before acquiring a pig. Happy pigs make happy meat and happy owners too.
