A Scots pooch collapsed and nearly died after scoffing a pile of toxic horse manure.

Cocker spaniel Thor was poisoned by an equine de-wormer in the poo, which is incredibly toxic to dogs.

Owners Caroline and Gary Irons say their beloved pet ended up in a "comatose state" on Sunday, May 1, after he was taken for a walk in the Sidlaws area of Dundee.

Vets made Thor sick using activated charcoal

A vet forced Thor to vomit out the poison and saved his life.

The manure is believed to have contained ivermectin, a parasite-destroying chemical which is incredibly toxic to dogs.

He was "unable to walk or even stand up," said Caroline.

She said: "It happened on Sunday, myself and my husband were away for the night so my mother-in-law, Dorothy, was looking after him.

"She took him out for a walk in the Sidlaws on Sunday morning and there was a pile of horse manure which he saw and he must have thought oh I'll have that.'

"He scoffed a lot of it before my mother-in-law could stop him, then they just continued on with the walk and he was fine.

"About three hours later he vomited the horse poo up in the living room, but she just sort of thought he had it coming.

"Once she was done cleaning it up she noticed that he wouldn't stand up or anything."

Caroline and Gary soon arrived home and raced their pet to Vets Now on King's Cross Road.

As they drove there, Thor began to become even more unwell, with his owner saying it was "like he couldn't even see us".

He was rushed inside the clinic by vets, who gave him a drip and used activated charcoal to make him throw up as much of the manure as possible.

Thor continues to recover from his ordeal at home

Caroline added: "About an hour after we dropped him off we got a call to say that he was in a comatose state and that the drip had absorbed a lot of ivermectin.

"Luckily, he's starting to feel a bit better now. He's not quite his usual crazy self but he seems to be a bit more back to normal."

Ivermectin can be deadly to certain types of dogs, with symptoms including dilated pupils, tremors, drooling, seizures, comas and the inability to breathe.

Caroline is now trying to make other owners aware of the threat it poses, saying: "I'm glad that more people know about this now.

"It's a difficult one to protect against because when you're out in the countryside you do want to let your dog off the lead for a bit so they can explore.

"I guess that my best advice would just be to keep an eye on them when they're about, and make sure they're not eating any manure.

"I think people forget how harmful it is."
