Contents of "Pig Bobby 1":

Pigs want to be "sheepdogs"? This is a ridiculous joke! But baby pig did it by his own efforts. Piglet was born in a pig farm. Like all pigs, he was raised and waiting to be slaughtered. But the difference is that the baby has an "ideal"-he wants to be an excellent "sheepdog". When he was adopted by a farmer, his ideal was initially realized. He chased the sheep away with Mother Dog, and all the animals laughed at him. Of course, the sheep refused to listen to the stupid pig. But the baby touched the sheep with his sincerity and friendliness, and they began to cooperate with him. Once, the sheep was attacked by wild dogs, and the baby drove the wild dogs away with his courage to protect the sheep. After the dog's father was injured, the farmer decided to let the baby pig take part in the sheepdog competition. The judges and the audience burst into laughter. How can pigs take part in the sheepdog competition? But with the help of "dog father" and "dog mother", piggy finally won the competition through his own efforts. Thus changed the fate of his life!

Judging from what you are looking for, it should be "Pig Baby 2 Pigs Going to the City"! But 1 is also very nice!
