 Further Adventures of Lad quickly became a best-seller and was praised by both new readers and existing fans. Critics, however, gave it more mixed reviews. The Literary Digest called the stories "delightful sketches" that invoked a feeling of "privilege [at being] admitted to the friendship and to obtain the devotion of an animal like Lad." The reviewer for the Springfield Republican found it as "entertaining" as the previous novel, and felt it was "written with the same understanding of dog nature which made the other stories universally read." A reviewer for the Olympia Daily Recorder considered it a "charming story" and a "worth while" book, calling Lad both "delightful" and a "great hero". However, Isabel Paterson, of the New York Tribune, considered Lad to be an unbelievable and undesirable dog and felt that Terhune wrote in a "rather hysterical style" whose "incessant piling up of the agony and adjectives [was] wearing." Despite these failings, she did note that dog lovers would likely enjoy the book.
