The movie you are referring to is "The Shaggy Dog" (2006), where a man named Dave Douglas turns into a sheepdog after being bitten by a 300-year-old dog.
Not a disease, but some form of Black Magic turns him into a shaggy Canine, or Dogman if you will. It is played for laughs, eventually he comes back to human form so all ends well. An enjoyable twist on the well Werewolf film but played in a non-threatening, comic fashion. Not a bad idea. Woof Woof!
