Whether your dog is bothered by bonfire night depends to some extent on his personality but mostly on your leadership, so what you do when your dog freaks out on November 5th is more important than what the dog does.
 
When we are scared we often feel better if someone puts a reassuring arm around our shoulders or offers a few soothing words.  But dogs are not humans and to offer your dog a cuddle and to talk reassuringly to it when it is in an anxious state will make the situation worse, you are giving him attention for this behaviour and therefore re-enforcing the fear.  

 

What a dog really needs from you at this time is good leadership which means convincing him that you are in charge and that there is absolutely nothing to worry about.  

The key thing to remember is not to engage with your dog when it is stressed.  This may be initially very difficult for many dog owners but it becomes second nature with a little practice.  If the dog comes to you for attention or runs into a corner shaking, don’t react. If necessary, just hold the dog still, not stroking him or engaging him in anyway, your dog  will come to understand that you are calm and if you’re not worried then he needn’t be either.
 
It is worth considering that your dog’s fear of fireworks is probably just a symptom of something else.  He possibly believes he is responsible for your safety, so try not to fuel this belief.
