How poisonous are adders?

Adders are famous for being the UK's only venomous snake but while the bite can be painful and cause inflammation, there is generally very little danger to humans.

The bite can be very dangerous to very young, ill or old people.

Medical attention should be sought immediately if conditions worsen.

What you should do if you're bitten by an adder?

According to the NHS website, those who have been bitten by an adder should remain calm as most snake bites in the UK are not serious.

They should then keep the affected part of the body still and lie in the recovery position before taking paracetamol for the pain.

Remembering the colour pattern of the snake is also advisable so the doctor can treat the bite better.

Victims of snake bites should also remove any jewellery and loosen the clothes around the bite in case of swelling.

What should you do if your dog is bitten by an adder?

They should then try and remember what the snake looks like or take a photograph of it, so the bite can be treated more effectively.

You should then call your vet to inform them of the situation before bringing them to it.
