The Singin' Strays are a group of singing dogs in The Fox and the Hound 2.
The group is first seen by Tod and Copper at the fair when they meet. Copper dreams about joining them and does. The first time they sing, the show becomes a success. After Tod lies that Copper is stray, Cash, the group's leader, lets Copper join. Towards the end of the film, Copper tells the group that harmony is important, and they sing the song We're in Harmony (reprise), which continues as Tod and Copper play around.
