Adder Bites Surge: Pet Owners Urged to Stay Vigilant

Pet owners across the UK are advised to exercise caution this summer due to the risk of adder bites to their dogs. Between March and October, these venomous snakes bask in the sun, posing a threat in areas like Cornwall's sand dunes. One owner recounted how his two dogs were bitten in April 2025, necessitating expensive antivenom treatment and costing approximately £2,500 per animal.

Wildlife experts emphasize that adders are elusive and defensive, not aggressive. They recommend keeping dogs on leads and avoiding long grasses. The UK's only native venomous snake is protected under the Wildlife and Countryside Act 1981, yet its numbers are declining, with projections suggesting they could disappear by 2032.

Veterinary advice stresses that while uncommon, suspected adder bites are emergencies. Symptoms range from mild pain and swelling to severe collapse. Prompt action, such as keeping the dog still and carrying it to a vet, is crucial. Some suggest bells on collars can alert snakes to a dog's approach. Conservationists aim to protect the species, urging people to avoid disturbing them to aid reproduction and prevent extinction.
