Typically, I advise distressed bulldog owners to try and have their bully move his/her head and neck, distract them with a toy, or a treat.

Distraction with food, toy, "let's go play or for a walk", or showing the leash, will usually stop your bulldog or French bulldog head tremors. 
You can usually stop your bulldog and French bulldog’s idiopathic head from shaking by distracting him/her with food, a favorite treat or toy, a leash ("let's go for a walk"), or having them tense their neck muscles by turning side to side.
