It is that time of year when adders are trying to heat up their bodies after the winter and are out basking in the sun. Because they are cold they are dozy and defensive and are mostly likely to strike because they can't move away as quickly as they can in the summer. Today a dog was bitten whilst walking on the marshes so please all be very careful, and in the event of a bite get to the local hospital or vet as quickly as possible. Whilst bites are not generally life threatening to humans (the last death was in 1975), it's a different matter for dogs. If you can carry you dog it is advised that you do so to stop them running and speeding up the spread of the venom. You can find out more about this protected species here.
