The Shaggy D.A.

Disgusted by the shady dealings of not-so "Honest" John Slade, Wilby Daniels decides to run for District Attorney, but when robbers steal the magic Borgia ring that "dogged" Wilby as a teenager, the fur really begins to fly! Once again, Wilby keeps turning into a large, talking sheepdog at the worst possible moments when the ring's magical incantation is read aloud. And when dirty trickster Slade discovers Wilby's secret, the race is on to see who can get their paws on the ring first! (official distributor synopsis)
