Dog walkers in Cornwall are warned to watch out for adders, a snake that can bite people and dogs.

Adders can bite people and dogs. Adder bites often hurt people and can cause swelling. See a doctor right away if an adder bites you. Bites in humans are rarely fatal. Snake bites pose a danger to dogs.
Take your dog to a vet quickly if bitten. The National Coastwatch warned people about adders on Facebook. Watch out for these snakes. Adders are enjoying the sunshine. Be very careful when walking your dog.
They are common on the coast but also live inland. These snakes are small and grey or brown. Adders have a V shape on their head. They also have a zigzag pattern down their back. Startled dogs could get bitten, and venom is dangerous.
Get veterinary help fast. The PDSA has advice for dog bites online. If a child or you get bitten, call 999 or 111. Then, follow the advice you receive from emergency responders.
