Northwest Hounded Police is a 1946 MGM Tex Avery short, starring Droopy, or Sgt. McPoodle, as he's called here.
The plot of the short is centered on Tex's recurring Wolf character, who has escaped from Alka-Fizz Prison and into the Canadian wilderness. Sgt. McPoodle of the North West Mounted Police is the only "volunteer" who will track him down. The rest of the short is spent on the wolf trying to escape Droopy, but to no avail, as he;s around every corner
It's essentially a remake of the first Droopy cartoon, 1942's Dumb-Hounded, but much wackier.
