PET OWNERS in Hampshire have been warned of potentially poisonous marshmallows sweets.

Pet owners across Meon Valley and Twyford said there has been a spate of dog deaths which could have been caused by the animal eating something poisonous while out on a walk.

Almost 100 people took to the internet to voice their concerns, revealing that three dogs had died in the Bishop’s Waltham area and another one had died in Shawford.

A few people posted a picture of a bag of marshmallows which were stuffed with some form of blue tablet or coated in a blue liquid and said they could be to blame.

Now a vet in Meon Valley has urged pet owners to be vigilant but could not confirm is there was any proof that these marshmallows existed.

Animed Vets shared a warning about the toxic sweets asking people to “be aware”.

The initial alert was sparked by the company Paul Dunnings Garage.

They posted on the internet: “As we have many customers in these areas we thought it would be a good idea to post this.

"Stay aware dog owners in Bishops Waltham and Twyford area, four dogs have died out on walks from poison spiked marshmallows.”

According to pet owners who took to social media, the field Shawford Down could contain some form of poison which is potentially fatal to dogs.

South Downs National Park in Dundridge Lane in Bishop’s Waltham is the other field named as potentially dangerous and three dogs allegedly died on a walk through this field as they were heading to the Hampshire Bowman pub.

Anna Simpson told her friends on Facebook that her dog had been put down after suspected poisoning. She said: “He became very ill after his usual walk in Bishops Waltham. Although the vet could find no trace of poison in his blood they are sure he ingested something that turned out to be fatal as there was no other reason for such a rapid decline. We are absolutely devastated at losing our gorgeous boy and to see him so ill will stay with us forever.”

Helen Glasspool also warned that it may not just be dogs that are in danger: “Cats are being poisoned in Bishops Waltham too. I know this is fact as my cat was one of them. I had to take him to Winchester vets as it was the weekend and he had all blood tests done. He didn’t make it.”

A vet from Animals At Home Meon confirmed that she had heard rumours about these marshmallows but didn’t know if it was true.

Helen Vernon told the Daily Echo that her customer Claire King’s 18-month-old chihuahua cross Pip was lucky to be alive after apparently eating something on a walk in Hatch Grange in West End as well.

Helen said that she didn’t know what kind of poison it was but the 18-month-old chihuahua cross was treated quickly and made a speedy recovery.

She added: “I don’t know if this is related to the marshmallow posts but a lot of pet owners are talking about something going round so I think everyone needs to be on the look out.”
