A pet owner thought her dog was going to die when it was savaged by another animal.
The tiny Jack Russell came under prolonged attack by a mastiff-type dog and was left with severe wounds to both sides of its neck.
The injuries came within millimetres of a jugular vein and Prince required an operation lasting three and a half hours.
Now Maureen Sweeney-Jones is hoping the owner of the other dog is found and prosecuted.
And she has stressed the importance of people keeping their pets on the lead.
Only the bravery of a passer-by in grabbing the other dog cut short the incident.
Miss Sweeney-Jones, a mum-of-three, of Abbotts Walk, Fleetwood, has had her dog for 12 months.
She said: “I was on the Mount and Prince was sitting by my side. This other dog came around the front and it was off its lead. It grabbed Prince by the neck and was shaking him like he was nothing.
“I was screaming ‘Get your dog off.’ The owner was trying to pull at it but she had no power over it at all. It was only when this man going by started to grab the other dog it loosened it’s grip.
“I was crying and screaming – it was awful.
“Someone was shouting the dog should be on a lead but the owner was shouting ‘he’s not a dangerous dog’ while Prince was still in its mouth.”
She added: “I just want to thank the man who helped us. He was called Neil McDermott, but that’s all I know.
“Thankfully my four-year-old daughter Rosalina wasn’t there. She was really upset when she saw what had happened.”
She added: “The couple who had the other dog were in their 60s. I just hope these people can be found and there will be a prosecution and they will pay my vet’s bill which is £300 so far.
“The vet said Prince was lucky because his jugular and windpipe were just missed.”
A spokesman for Wyre Council said: “We are working with the police to investigate this incident and are supporting the owner of the injured dog.
“Both the police and the council have powers to prosecute dog owners where offences are committed.”
