DOG walkers are being warned of the dangers of snake bites after several pets have been bitten this year.

Bredy Vets in Bridport has issued the warning after the practice revealed that it had treated three dogs for adder bites.

People are urged to be particularly vigilant on sandy heaths, rocky hillsides or moorlands as these are the places where adders are usually found.

There are three species of snake found in the UK: grass snakes, adders and smooth snakes. Of these, only the adder is venomous and a danger to dogs

British adders are fairly distinctive with the males having a silvery-grey colouration while the females can be copper or brown.

These snakes can measure as long as 60 to 80 cm when they are fully grown, according to the Woodland Trust.

Bredy Vets said in a statement: “Please be vigilant when walking, adders have been emerging from hibernation since around March time despite the weather being a little chilly lately, they are out and about locally.

“The adder is the only venomous snake native to the UK, and they are also a protected species.

“Adders are most commonly found on dry, sandy heaths, rocky hillsides or moorlands.

"Most bites occur on the legs or face and result in dark painful swellings, you may also see two small puncture wounds in the centre of the swelling, other clinical signs can include pain, lethargy, vomiting, bruising, bleeding and collapse.

“Adders will only bite in self defence, usually when disturbed or stood on.”

The vet goes on to issue some advice on what to do if you suspect your dog has been bitten by an adder.

It recommends to not panic, interfere with the bite, or apply a tourniquet and to contact a vet immediately.

The spokesperson added: "If you’re able to, carry your dog to your car and call us in advance on 01308 456771 so we can prepare for your arrival.

"Do not delay in seeking veterinary advice even if your pet is well as things can change quickly."

The warning comes after a woman visiting her parents in Beaminster had to take her dog to a vet in early April.

Lucy Crawford’s three-year-old golden working cocker spaniel Willow was bitten by an adder at West Bexington as the family walked along the beach.

Punctures wounds were discovered on her muzzle and it is thought she was bitten by the adder when sniffing around a bush.

Thankfully, Willow recovered well from the bite and there was no need to give the pup anti-venom.
