Ruth agrees to babysit Betty Wilder's infant twins, but the young mother arrives early and reluctantly leaves Timmy and Lassie to care for the babies until Ruth returns from an errand. Timmy thinks it will be a cinch--until a marauding hawk chases a frightened pigeon into the bedroom where the babies are sleeping.

A blind dog is trapped in a skip-loader and in danger of being buried alive. Lassie risks her life to save the handicapped pup and Timmy helps the dog's owner find work to pay for a sight-restoring operation for his pet.

A neighbor's prize bull strays onto the Martin farm and tries to attack Timmy. When the bull is later poisoned, the neighbor accuses Paul of the deed. Detectives Timmy and Lassie launch an investigation to find the real culprit.

When Timmy and Lassie bring home a litter of starving orphaned puppies, rescued from a maurading bobcat, the family tries to save them although one has already died of starvation. Inadvertantly, the pups teach Timmy, who's been relying on Paul to help him with arithmetic homework, about self-sufficiency.

Timmy observes what he believes is a wild horse which becomes a menace to the local farms but persuades Paul to convince the local farmers to spare the life of the horse which is later learned to be an escaped thoroughbred.

But when their son Billy Joe finds out his parents plan to give away his beloved dog Mitchell, he swears Timmy to secrecy after returning to the Martins', then he and the dog head for the woods--where deer season has just begun.
