PET owners have been warned to be "vigilant" after a 'dog was bitten by a snake'. 

Friends of Bellahouston Park have shared the warning on Facebook after a four-year-old pooch was believed to be bitten by an adder in the park on Saturday, April 6. 

The post says the dog "became lame" the following day and was treated for a severe infection on the Monday but his health "deteriorated" by Friday, 12.

A further investigation by the vet found a bite mark which is believed to have come from an adder. 

The post read: "My neighbour's dog became lame on Sunday, April 7, he appeared okay but he wouldn't put weight on [his] leg.

"As the four-year-old already had arthritis assumption was this was the issue and owners held off until Monday before heading to the vets.

"He was treated for a severe infection but I'm unsure if they linked it to his arthritis or something else.

"Anyway, the dog's health deteriorated by Friday 12 and after further investigation, they have just located bite marks which they believe to have come from an adder.

"The owner had him at Bellahouston Park (he runs in/out bushes) on Saturday 6.

"This is where and when they believe the bite occurred.

"Springtime is when adders are coming out of their hibernation. Please be vigilant.

"Fingers crossed the dog makes a full recovery."

However, a spokesperson for Glasgow City Council said there is no record of adders being in Bellahouston Park. 

They said: "Bellahouston Park is not the natural habitat for adders and we have no record of them being there."

Adders are the UK’s only venomous snakes.

They only grow to 50-60cm and can be brown or grey with a diamond pattern down the centre of their back.

While their venom is generally of little danger to humans, an adder bite can be painful and cause inflammation and medical attention should be sought immediately. 

If a dog is bitten by an adder, there may be swelling around the wound while the dog may show signs of pain, bleeding, bruising, lameness and may appear nervous. 

Owners should seek veterinary attention.
