Dog food is one of the phrases learned by a deaf Dachshund who has been trained to understand sign language.
Sparky, a one-year-old pup, has now been given a permanent home Missouri School for the Deaf after being trained in sign language over eight weeks by inmates at Missouri prison, reports the Daily Mail.
Michael Miller, a student at the school, revealed that if he cannot get the dog's attention, he picks him up.
He told the news provider: "I knew, like me, he can't hear anything. I feel that because I can communicate with him in signs that it's special."
Superintendent Barbara Garrison added that Sparky "fits in perfectly" and that he likes his "new deaf family" at the school.
Sparky was trained through the Puppies for Parole programme from the Missouri Department of Corrections.
Inmates train homeless puppies so that they are more adoptable, meaning fewer dogs are euthanized.
