The puppy was resisting
The officer swiftly lifted the net containing the puppy off the train tracks and placed the distressed animal in the little cage they had prepared. When they close the little cage door, the puppy starts trashing in against the cage’s side. Every step is made in the direction of the railway tracks.
Not even calm in the cage
The puppies’ strength and determination cause the cage to tumble over. None of the people present have ever seen anything like this before. Why was this animal so desperate to be on the railway tracks? Whatever the rationale, it was primarily for future consideration.
