DERWOOD, Md. (WUSA9) -- A lonely dog can't stop singing the blues.

Juice is the longest dog resident of the Montgomery County Animal Services and Adoption Center. A year ago, Juice was brought to the shelter by his family after the family moved and no dogs were allowed, as reported by the Examiner.

To give Juice a break from shelter life, a staff member took him home for a "sleepover." When Juice returned to the shelter, he wouldn't stop crying.

In a time lapsed video on the shelter's YouTube page, Juice can be seen and heard crying for hours.
