Walter, a five-month-old, rescue puppy, comes to Grandma's house for his first visit, he learns that his curiosity and Grandma's rules often clash. After exploring every corner of her house and chewing a few of Grandma's and Grandpa's treasured possessions, Walter and Grandma finally go for that long-awaited, promised walk. During this adventure, Walter meets an older dog, whose labored movements and gray-face trigger a brief memory from his past, hinting at the reason for Walter's becoming a rescue dog. The somber tone of the escapade changes quickly, however, as Walter meets the minis and talls (otherwise known as people) and licks the delicious fingers and faces of the minis. When he is snubbed by two stuck-up poodles, Walter is thoroughly surprised and miffed. All ends well, however, when Mom and Dad return and "rescue" Walter once again, this time from Grandma.
