If he usually does listen, or look up at you, or come, when you call his name, and suddenly he isn't doing that, it means that SOMETHING is definitely wrong. He might only have had a concussion, but even that is serious.
Hey listen, don't try and guess what it might be, or guess (if he looks a little better) that he might be ok now. DON'T GUESS, take him to be checked out. Guessing just wastes time. And just in case (?) your parents don't agree, perhaps you could show them the answers you've received on our forum? People here all know quite a bit about dogs, some may even be veterinary nurses, or have learned a lot from having dogs of their own. And it's better to be safe than sorry.

It is so good that you care like you obviously do for this little puppy. You have so much common sense and good instincts. This pup needs the vet! And you know that. Do what Ghilly says, bug your parents NOW!! The quicker he is seen and given medical help the better. Good luck. Let us know what happens, hey?
If you are a child, I know that this is out of your control, however you need to make your parents aware that if this puppy is seriously injured, there can be serious consequences for them if he is not taken to the vet. It is considered a crime to know that an animal is injured and refuse it veterinary treatment. Please convince them that it is NECESSARY for this puppy to be seen by a vet. Even if they bought the dog for you, as the adults in the family, they are the ones who are responsible for its veterinary care and well-being. To ignore that when the puppy could be seriously injured is negligence. Stay on them. Keep bugging them. The puppy needs to see a vet.
