When Rene leads Big Red to run into Haggin and Emile for the first time, he had tied his belt around the dog for a collar and leash. After they examine the dog, and Mr. Haggin immediately leads him off, the dog's now properly leashed, and Rene has his belt in his hand, with no cutaway with them replacing the belt.
Emile says that Big Red's right paw is injured (in French), but he examines the left paw (which was the one previously caught in the fence).
