There are some things you can do to helps your pets be more relaxed and settled during this time.
This might seem quite obvious but it is worth considering keeping your cats inside during this time. Even the most independent of cats can get spooked with fireworks and they could run away and get lost or run into oncoming traffic. If your cat is reluctant to stay inside you could consider a warming pad so muggles has a comfy place to sleep.
Create a 'Den'
This is a place where your pet can go and hide if it all gets too much.
If your dog is used to a crate you could place a large blanket on top to darken the area a little. Put their favourite toys inside as well as a piece of your clothing. The familiar smell will help them to feel safe.
If your pet chooses to go into their den leave them to it. They will pick up on your own anxiety if you keep checking up on them.
If your dog doesn't normally use a crate it might not be the best time to introduce one. You could create a comfy space in your under stairs cupboard or underneath your dining table.
Keep a TV/Radio on
The background noise will help to keep things as normal as possible and will reassure your pet that there is nothing to worry about.
Don't shout or tell them off
Your dog might bark a lot more than usual. This is just thier way of telling you they are scared. By shouting at them you could make them more worried and the behaviour could get worse.
Use a pheromone diffuser
For those pets who get extremely worries you can use a diffuser which releases pheromones to ease their anxiety. It is best to introduce a diffuser slowly over time, it most likely won't have the desired effect on the first try. There are diffusers available for both dogs and cats.
Use a ThunderShirt
Thundershirts apply gentle, constant pressure which is similar to an infant being swaddled. This is very calming and they work extremely well. Thundershirts are available for both dogs and cats.
Acclimatize your pet to the noise of fireworks
There are noise CD's available which play fireworks. This gives you a change to get your pet used to the noises and not worry. Start by playing the CD on a low volume and gradually increase until it is playing to the same volume as regular fireworks. You can give treats along the way when your pet is acting calm and not reacting adversely to the noise.
Don't leave them alone
I know it might ruin your social plans but if your pets are known to be scared of loud noises they could get more worked up if you aren't around to help them deal with it. They could also start showing unwanted behaviours such as chewing furniture or defecating in the house. Have a gathering at home instead and include your pet in your plans.
Bonfire/Fireworks night can be a stressful time for your pets but as long as you are aware of the potential pitfalls everything should run as smoothly as possible.
