The Kennel Club has issued a warning to dog owners about what to do if your dog is bitten by a venomous snake.

Adders have been spotted on Portland and surrounding areas as they are this time every year.

The Kennel Club issued the following advice: "Your dog is most at risk of being bitten by an adder in April, when these snakes first emerge from hibernation.

"Dogs are most frequently bitten in the early afternoon when adders are most active after the midday heat.

"If your dog is bitten, using a tourniquet or trying to suck out the venom may cause infection or restrict circulation, causing further complications.

"If you think your dog has been bitten by an adder take them to the vets immediately.

"If you see an adder, you should leave it alone. It is a protected species and it is illegal to harm or kill them."

Paul Burkhardt, who lives on Portland, said: "They need to "solar charge" in the mornings, bathing in the sun. Usually, by mid-afternoon they disappear but this can be earlier depending on the heat of the sun.

"I've seen a fair few photos already this year but no more than in previous years. Coastal paths and heathlands are good places to spot them. Dogs are most at risk from a bite so walkers should be vigilant."
