As of 2016, this is the last film in the Walt Disney Animation Studios canon where voice actor Frank Welker receives an on-screen credit for providing animal vocal effects until Strange World (2022). In later films, he'd simply be listed under the Additional Voices or go Uncredited. As well as this film being the last animated film of Frank Welker's to do so until Smurfs: The Lost Village (2017).
