Allan Thorne was walking in the Lammermuir Hills last week, when he spotted an adder – the UK’s only poisonous native snake.
His sighting marks the start of adder’s breeding season. Adders hibernate from October to March, but they begin to emerge as the weather gets warmer.
While the species are not aggressive, the creatures may bite if they feel threatened.
Their bite is rarely fatal to humans, however, adder bites have killed dogs in some cases.
She told Wales Online that her vet had another dog come in with an adder bite on the same day, and said: “It’s definitely a cause for concern and I'd like to ensure more people are aware of the seriousness of adder bites and to make sure they keep a close eye on their dogs."
Scottish SPCA head of education, policy and research, Gilly Mendes Ferreira, said: “Adders come out of hibernation in spring and are the only venomous snake in the UK.
“They are not aggressive snakes and only tend to use their venom as a last resort, for example if they are stepped on or cornered.
“Dogs can also occasionally disturb adders while on their walk. If you are worried your dog has been bitten by an adder please seek veterinary treatment immediately.
“If anyone does come across an adder while out walking we’d simply advise them to give the snake plenty of space and leave it alone. If you are concerned you may have been bitten by an adder we would advise that you seek immediate medical attention.”
According to the Scottish Wildlife Trust, adders, which are a protected species, are relatively small, stocky snakes and prefer woodland, heathland and moorland habitat.
