Set on a farm, the show focuses primarily on three particular puppies: Lucky, TV expert, leader, and a runt; Rolly, his loyal, scholarly, and always-hungry brother; and Cadpig, their sister, also a runt. The three siblings are often joined Spot, a chicken who wants to be a dog and a member of the "Bark Brigade." Early promotional material had listed "dictatorial Penny and mischievous Patch" as two other puppy cast members, but the highlighted puppies were whittled down to three. (It should be noted that Penny is an alternate name for Cadpig.)
Other puppies appearing in the show have included the brave, three-legged Tripod; Dipstick; the constantly urinating Wizzer; and Two-Tone. The show seems to be a blending of both the original animated film and the live action feature.
