This is a terrifying scene captured by a surveillance camera. A pickup truck is parked by the side of the road, and a dog named Caesar is getting ready to go on a date with his girlfriend. However, as Caesar was about to approach his girlfriend, he suddenly stopped, walked towards the parked pickup truck, and prepared to relieve himself. However, Caesar sniffed the tire. He found the smell somewhat pungent, so he took a deep breath. Then he suddenly fell to the ground, began to struggle wildly, and screamed loudly, appearing to be in great pain. After a while, Caesar lay on his side on the ground as if he had fallen asleep. His girlfriend noticed that Caesar hadn't come to find her for a long time, so she went to look for him. But by this time, Caesar was already lying on the ground. The owner of the pickup truck passed by Caesar's place after finishing his business, but he didn't notice Caesar's abnormal behavior, thinking that Caesar was just sleeping on the ground. After a while, the owner ran over, saw the motionless Caesar, and didn't know what had happened, so he ran back to call for help to see what had happened. Finally, do you know what happened to Caesar?
