traxtion,

Welcome to NeuroTalk.

It sounds like you suffer from Concussion Anxiety Syndrome. That can be caused by pre-existing anxiety, especially health anxiety or a low threshold for developing inflammation in the brain.

I have never heard an anecdote about a person getting concussed from their dog in the 15 years I have followed online concussion forums.

A 35 pound dog does not have the impact force to cause a concussion.

Rather than address whether this could be a concussion, I would hope you would answer a simple question.

What difference does it make whether this could be a concussion?

What would you do differently going forward?

Would you ask for time off work or from studies.... just because?

Would you plan your future anticipating developing CTE in the next few years?

You can't back up time and change what already happened so why does a probable diagnosis even matter?

Are you looking for information to feed and justify your anxiety?

btw, I've had over 14 concussions over a 50 year span. I never did anything different after any of them except for a hospital stay after the second, very severe concussion.
