CRUEL dog poisoning thugs have left a trail of devastation for pet owners throughout Glasgow.

In day three of our investigation, we reveal the heartache of a woman whose late mother's dog was killed after swallowing chicken which was laced with anti-freeze.

Kerryann Reilly, 21, took in her tragic mum Rita's beloved Jack Russell named Bonnie after she passed away aged 60 last year.

But in February this year the pooch ingested poison near Craigton Primary School in Glasgow and died in less than 48 hours.

Social care assistant Kerryann, from Craigton, recalled: "I took her for her last walk and I noticed she had something in her mouth.

"I went to pick it up and got it out her mouth straight away and didn't think anything of it until my brother woke me up to say that she was sick.

"We monitored her for around 24 hours but she had really bad diarrhoea and was sick again the following day.

"She was drinking loads more water than she normally would and didn't want to go to the toilet to we took her to the emergency vets.

"Her back legs were falling away from her and she was stumbling about like a drunk effect, which can be caused by antifreeze."

Before the seven-year-old dog was rushed to the emergency vets, Bonnie's condition rapidly deteriorated.

Her body began to shut down and she was unresponsive to antibiotics and steroids, despite the vet's desperate attempts to save her.

Devastated Kerryann said: "The vets phoned me to say her brain function wasn't working and that there was nothing they could do to save her.

"We lost my mum last April so Bonnie was like a comfort for me and my brother when we took her in after mum died.

"Having Bonnie with us felt as if we still had a massive part of my mum with us and that has been snatched away from me and my brother by some selfish individual who shouldn’t have a place in this world."

"I can’t think of a reason why anyone would poison food for any animal. It's disgusting."

We told this week how animals poisoned by lethal substances can be killed in less than 30 seconds and experience "excruciating pain."

It comes as the Scottish SPCA revealed they had received reports of more than 54 dog poisoning cases since January 2018.

This week the Evening Times has been running a special series looking at the horrific impact of the inexplicable crime.

Sadly cops find it "almost impossible" to nail the perpetrators who leave toxic food in public parks.

Kerryann said: "This definitely has to be taken a lot more seriously.

"It's absolutely sickening, I can't understand why people would do it to an animal.

"If you don't like dogs then stay away from them - don't poison them and ruin people's lives.

"It's like murdering a child so there should be stricter laws in place if you harm an animal.

"This ruins families, we had Bonnie snatched away from us and it's horrible.

"This is causing animals loads and loads of pain and suffering that lasts for days.

"My other two dogs are also suffering really badly knowing Bonnie's no longer in the house."

Glasgow Tory MSP Annie Wells said the problem is worse in Glasgow than other areas in Scotland.

The politician believes security should be reviewed in public parks for the safety of not just animals, but people also.

She said: "It has came to my attention quite recently and when I was in Maryhill a few weeks ago one of the neighbours had thought somebody had put poison treats through his letterbox and his two dogs had been unwell.

"What would you have in your mind to say, let's go put anti-freeze in a dog treat? I don't get it - is it a new craze?

"When you look at safety in parks, even when you look at murder and attempted rapes, we need to look at the safety of everyone in our parks.

"It's meant to be a place you can go and take your animals so we need to make sure that there's patrols being put in place and possibly CCTV if need be.

"I do think that we absolutely need to tackle this and that people need to be looking out for the perpetrators.

"We also need to educate young people to show the impact of this on animals also."
