What to do if your dog is bitten by an adder!

Rise in Adder Sightings Reported in North Yorkshire

As the spring and summer bring warmer days to the landscapes of Yorkshire, many of us are heading further afield on our dog walks, exploring the moors, woodlands and fields. Whilst they are very shy, it’s worth noting that adder sightings have increased over recent years - possibly due to warmer weather. Whilst adders are not aggressive and more likely to retreat if disturbed, curious dogs can be at risk of a bite!

Usually there is a successful outcome to an adder bite, but it is a major medical event and veterinary care is essential. If your dog has been bitten, you may notice sudden yelping or limping, especially after exploring undergrowth or rocky areas. Common symptoms include swelling around the bite site (often on the face, legs, or paws) pain, lethargy, vomiting, drooling, or difficulty breathing. In severe cases, the venom can cause collapse or affect the heart and nervous system. If you suspect an adder bite, don’t wait for symptoms to worsen - act immediately.

What to do if your dog is bitten...

  1. Stay calm and keep your dog still. Panicking can increase your dog’s heart rate, spreading the venom faster. Encourage your dog to remain calm and avoid running or jumping.
  2. Carry your dog if possible. If you’re far from your vehicle try to carry your dog to reduce movement and slow venom circulation.
  3. Do not touch the bite area. Avoid running, squeezing or applying ice or heat to the wound as this can worsen the injury or spread the venom.
  4. In NO circumstances should you attempt to tourniquet a limb – this will result in local tissue necrosis and will not prevent the venom spreading.
  5. Do not rely on Piraton or other antihistamines. No studies have been done which prove its efficacy. You do need to see a vet.
  6. Contact us immediately on our emergency number 01765 602396. Let us know you suspect an adder bite so we can prepare for your arrival. Time is critical and professional treatment is essential. Our Ripon hospital is open 24 hours a day.
  7. Monitor your dog. Note any symptoms or changes in behaviour enroute to the vet, as this information will help our team provide the best care.

To reduce risks, keep dogs on leads in adder-prone areas, especially during spring and summer when snakes are active. Stick to clear paths and avoid tall grass or rocky outcrops where adders may bask. Please remember that adders are a protected species and you mustn’t attempt to hurt or injure the snake – and certainly, never be tempted to pick one up.

Remember, if you need us we are available 24/7 at our RCVS Accredited Hospital in Ripon, call us on 01765 602396.
