Thunderstruck

I generally love a good thunderstorm, with the exception of all the damage caused in the one we received last night.  My dog is terrified of thunder, fireworks and loud booming noises.  He starts shaking uncontrollably and runs for cover.  I’ve tried many things to calm him including wrapping him in a blanket and holding him until the storm passes. Someone recommended a bit of CBD oil.  Someone else suggested a thunder jacket.  None of these have worked.  I feel so bad for the poor little guy as he becomes more and more distraught with each boom.  It feels as bad as not being able to comfort a scared or sick child.  I am open to any suggestion and willing to try anything at this point so bring on the tips.  How do you comfort your pet when they are scared of the thunder?
