Heart-breaking footage shows the moment a teenage girl cried out for help as her beloved pet lay dying after he was attacked by another dog before its owner quickly left the scene.
Renata Aladenika, 18, claims she was out walking her miniature pinscher Rocco in Woolwich Common in London when a bullmastiff, that was not on a lead, ran over and shook the pooch 'like a rag doll'.
The quick-thinking teen quickly whipped out her phone to film the dog's owner dragging it away by the collar as Rocco lay bleeding on the ground.
In the clip, Renata can be heard sobbing and saying: "He's dying."
Sadly, Renata was forced to say goodbye to her 'best friend' as his injuries were so severe vets were unable to save him.
Despite the pooch not surviving the teen and her family have been left with a hefty £1,300 vet bill and have now set up a GoFundMe to try and raise funds to cover the cost.
Renata said: "It felt like this giant devil dog versus our tiny Rocco.
"He was a tenth of his weight, so he didn't stand a chance. To lose him like this was so traumatic.
"The dog wasn't on a lead. It was awful, he ran over and grabbed Rocco by the head and started shaking him.
"The owner tried to drag it away by the ear, but it must have been 70kg.
"She apologised and said she would give me a lift to the vet, but when she got into her car she just drove off.
"Rocco was my best friend. The house is so empty without him and it feels weird going to sleep without him on my bed.
"He did so much for my mental health and was just the sweetest, kindest dog you could imagine.
"Walking him really helped me come out of my shell and it gave me a reason to leave the house. I met friends through him, he did so much for me."
Renata says her and Rocco were out for a walk at around 8.50pm on Sunday when the bullmastiff came charging over and sank its teeth into him.
Describing the horrific incident she said: "The other dog was off the leash so Rocco approached it and the dogs stopped and looked at each other.
"Rocco gave a little warning growl and the next thing I knew the dog had Rocco's neck in its mouth and was shaking him around.
"He was screaming for help. I could hear him yelping the whole time, and I was screaming trying to get him away.
"The woman was telling the dog to let go. I was trying to pull him away but it wasn't working as the dog's jaw was very strong.
"That went on for a minute and after a while Rocco stopped moving and he was still being shaken around for another minute."
After the woman drove off, Renata called her mum and they took Rocco to the emergency vets where was monitored over night, but the next day the family were given the devastating news that the dog had catastrophic haemorrhaging in his neck and would have to be put to sleep.
A Met Police spokesperson said: "There have been no arrests and enquiries continue."
