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 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 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.
