What to do if your dog is bitten by an adder

Adder bites can be a frightening experience for both you and your dog. Adders are the only venomous snakes native to the UK, and while their bites are rarely fatal, they can cause serious harm if not treated promptly. Here’s a guide to help you act quickly and effectively if your dog is bitten by an adder.

Stay calm and keep your dog still

The first and most important step is to remain calm. Your dog will pick up on your anxiety, which can make the situation worse. Movement increases blood flow, which can spread the venom more quickly through your dog’s body. Keep your dog as calm and immobile as possible.

Identify the snake (but only if it’s safe to do so)

If you saw the snake, try to remember its colour and markings. Adders typically have a distinctive zigzag pattern along their back. However, do not put yourself at risk trying to identify the snake. Your safety is just as important.

Recognise the symptoms

Adder bites usually cause immediate swelling around the bite site, which may be painful. Other symptoms to watch for include:

  • Lethargy or weakness
  • Vomiting
  • Drooling
  • Pale gums

These symptoms indicate that venom has been injected and veterinary care is urgently needed.

Seek veterinary help immediately

Time is of the essence. Contact your vet and let them know you’re on your way. Quick treatment can significantly reduce the risk of complications. Your vet may administer antivenom and provide supportive care, such as pain relief and fluids.

Avoid home remedies

Do not attempt to:

  • Suck out the venom
  • Apply ice to the bite
  • Use a tourniquet

These methods can worsen the situation or waste valuable time. The best course of action is to get professional veterinary help as soon as possible.

Preventing Adder Bites

While it’s impossible to eliminate all risks, you can take steps to reduce the chances of your dog encountering an adder:

  • Stay vigilant: Adders are most active between March and October, especially in sunny weather.
  • Avoid known habitats: Adders are often found in heathlands, sand dunes, and woodland edges.
  • Keep your dog on a lead: In areas where adders are common, keeping your dog close can help you spot potential dangers.

Adder bites are a medical emergency, but with prompt action and veterinary care, most dogs make a full recovery. By staying calm and following these steps, you can ensure the best possible outcome for your furry friend.
