A Chesterfield vets has issued a warning to dog owners after an adder was spotted on Chesterfield Canal at Hollingwood.
Carrick Veterinary Group have posted advice on their Facebook page.
Adders are rare to see and their bite is uncommon in dogs.
Most bites occur on the lower limbs or the muzzle, this is because dogs inadvertently sniff or stand near a bush that houses a sleeping snake which acts in self defence. Often the attack is not seen by the owners.
Signs of a bite are rapid swelling of bitten area, fang marks may be present (but not always easily seen), depression and in rare cases anaphylactic shock. Bites are rarely fatal.
Treatment is wound management of a puncture wound, fluid therapy if their are signs of shock, cage rest
Do not suck the venom out, tourniquets or cutting the wounds. They do not work and can cause more harm than good.
If you do think your pet has been bitten by an adder or any other snake contact your vet immediately.
