Continuity mistake: When the Wolf shakes the plastic surgeon, telling him to give him a new face, the surgeon's moustache disappears for a few frames. (00:05:30)
Continuity mistake: When the Wolf jumps into the lion's mouth at the zoo, one of the stripes on McPoodle's sleeve changes color and then reverts back. Also note, the stripes on Sergeant McPoodle's uniform sleeves repeatedly change between pointing down and pointing up (despite the reveal in the cartoon's last shot, all stripes should be identical).
Continuity mistake: When the wolf tells the plastic surgeon to change his droopy face back to his usual face, the surgeon has a bald spot with a moustache. When the surgeon gives the wolf a mirror to see his new look, the surgeon is now completely bald and the moustache has gone.
Continuity mistake: When the Wolf tells the plastic surgeon to change the Droopy head back to his own head, he is wearing a hat which disappears in the next shot.
Continuity mistake: When the Wolf runs to the cabin, the front door is initially made of wood. But when the Wolf opens all the doors and finds McPoodle waiting for him, the front door now has molding on it.
Continuity mistake: When the Wolf is reading the signs, he stops at one of them and you can see behind them there is some barbed wire. But after a quick cut of McPoodle riding his pony, we return to the Wolf and the sign and barbed wire have disappeared.
Continuity mistake: When the Chief of the Mounted Police is showing the other officers the poster of the Wolf at the headquarters, the wording under the picture of the Wolf changes between shots.
Continuity mistake: When the convict trips outside the plastic surgeon's office, the sign on the window reads "plastic surgery" which changes to "plastic surgeon" in the very next shot.
