Little Orphan Airedale is a Warner Bros. Looney Tunes cartoon directed by Charles M. Jones and released on October 4, 1947.
[1] Its major significance is its status as the official debut of Jones' version of Robert "Bob" Clampett's character, Charlie "Rover" the Dog.
While looking for prospective masters, Charlie imitated several passersby (including a man with sleepy eyes and big lips as a caricature of Mel Blanc).
Porky, believing that the dog is female and is pregnant, takes him in, puts him into bed and feeds him with some milk and broth.
After being begged several more times, Porky seems to finally take Charlie in, before trapping him in a shipping crate to send to Australia.
