Horace Homer Higgins III despises dirt. And the outdoors. And ducks. But when his person, Ellie, moves to a farm called the Homestead, the anxious Boston Terrier is forced to adapt. As if that isn’t enough to strain his nerves, Ellie adopts a perpetually cheerful potbellied pig named Bunwinkle to be his baby sister. Bunwinkle is delighted to be on the farm despite the stuffiness of her new canine brother. She’s sure she’ll crack his shell eventually—no one can resist her cuteness for long—especially once they bond over watching a TV pet-tective show. When the duo discovers that some neighborhood animals have been disappearing, they decide to use their new detective skills to team up to solve this barnyard mystery. Is it a mountain lion? Or their suspiciously shot-loving veterinarians? Only one thing seems certain: if they don’t figure it out soon, one of them might be next.
