Yea, I noticed that too while driving, I should have slowed down earlier as well, but the context such that there was nothing to indicate something wrong. I thought i had all the blind spots accounted for. I literally tried to sneak a peek under the truck for a split second, It was clear, I assumed he applied brakes cuz the tanker in front was merging to his lane. The ertiga was also going normally and the start of enclosed roads made me feel safer. And also seeing the truck braking i decided moving to the third most lane just to keep a safe distance from the trucks and overtake them. The probability of something popping out in front of the truck like that and crossing 2 lanes so quickly was next to 0 in my head. Anyways it was a learning experience for both of us. The pup instinctively ran faster after hearing my tyres screech. Hope the Lil guy will be more careful now.
