SLITHERING out to bask in the sun, the adder comes out of its slumber.

But following reports that a spaniel dog died after being bitten at Birkrigg Common, experts say there is no need to be alarmed.

While a small dog is vulnerable to the effects of the venom, especially if the bite occurs on its head, the snakes pose little risk to people.

David Harpley, conservation manager at the Cumbria Wildlife Trust said: "They are not very dangerous. As long as people do not touch them they are fairly harmless."

"They will usually try to get away from you as quickly as they can."

The adder is one of only four native British snakes and the only venomous species.

Bites are more likely to occur in the summer when people wear flip-flops.

But while the NHS advises to ring 999 if you are bitten, the venom is not deadly.

As Mr Harpley explains, "It's much more serious for small dogs than it is for people."

"If you leave them alone they will not come anywhere near you."
