A piglet fell out of a livestock truck in Kansas and was found on the road by a family who fortunately happens to run a vet hospital. They decided to take the pig in and take care of the baby animal, naming her Mu Shu.
When the family dog, Hunter, met the piglet he started to look after Mu Shu, and an odd friendship was formed. Hunter helps lead the partially-blind pig around, plays with her and keeps her clean. The pair are completely inseparable now, so the family has decided to adopt Mu Shu permanently.
