Tonight is Bonfire Night – remember, remember, the fifth of November – to mark the failure of the "Gunpowder Plot".

More than 400 years ago, on this date in 1605, there were 36 barrels of gunpowder that were found beneath the Palace of Westminster.

According to English Heritage, Guy Fawkes, the man who had planned to set off the explosion, did so to spark a Catholic uprising by blowing up parliament and everyone in it – including King James I.

In short, the interception of the Gunpowder Plot was seen as an act of God, hence the celebrations that have since ensued.

While religious connotations with Bonfire Night have dissipated, the tradition of lighting up the night sky with fireworks has lived on.

However, not everybody loves the colourful and loud explosions, especially animals. Vet Dr Linda Simon at Pooch & Mutt revealed eight "subtle signs" that fireworks is causing your dog anxiety.

"Anxiety-prone dogs, for example, those who already have separation anxiety and a fear of new places, tend to be more affected," said Dr Linda.

Signs of noise phobia during fireworks season can include:

1. Shaking
2. Whining or barking
3. Hyperactivity
4. Hiding away
5. Refusal to eat
6. Panting
7. Seeking more affection
8. Peeing or pooping in the house

"Signs may seem to start before you hear a noise, as dogs have such good hearing that they often pick up on noises before we do," said Dr Linda.

"Symptoms can go on for long after the fireworks have stopped too, as your dog’s stress hormone levels remain high."

To help calm dogs before the fireworks go off this evening, you are advised to "plan ahead".

"Make sure that your pooch is tuckered out from a day of walks, playing and mental enrichment before peak firework time," advised Dr Linda. "Being tired and worn out can help them avoid feeling anxious and scared."

Dr Linda added: "When fireworks start, be cautious not to act unsettled yourself. Dogs quickly pick up on our body language and stress levels and may become upset if you're anxious. Be calm and confident, and try not to fuss them too much."

Another tip is to "create a safe haven" inside your home by making a cosy den "away from windows". Dr Linda added: "Keep curtains closed and provide lots of blankets for your dog to bury themselves under. Have the TV or radio on in an attempt to drown out sounds too.

"Your dog may appreciate a nice long-lasting chew while they settle down for the night, or a soft, plushie companion to snuggle up with."
